How to Build Pull-Ups: From Zero to Selection Standard
A strength coach's guide to building strict pull-ups - from your first rep to selection volume - with the mechanism, progression, and sample workouts to get there.
Few exercises expose a candidate's training gaps quite like the pull-up.
A weak posterior chain hides under loose kit. A poor aerobic base hides behind a strong team carrying the slack on a tab. Bad shoulder mobility can be worked around until someone puts a Bergen on you. Pull-ups don't allow any of that.
It's just you, the bar, and whatever vertical pulling strength you've built. You either get over it, or you don't.
For most people preparing for selection, basic training, or general physical readiness, pull-ups sit somewhere between frustrating and demoralising. The standard everyone wants to be aiming for is north of twelve strict, solid looking reps.
The reality for many is two, three, perhaps half of one if you count the descent you survived rather than executed meaningfully and worryingly, a considerable number of soldiers cannot manage a single full rep. That is more common than people like to admit.
Pull-ups are hard. They are meant to be hard. The body is designed to climb, but climbing requires capacity, and capacity has to be built deliberately and it's not really something that we do in our day-to-day life anymore.
This guide is for the full bracket - from “I can't do one yet” to “I'm stuck at five and don't know why.” The starting points differ. The path forward is largely the same.
The first big obstacle: this isn't a problem to solve with just more fitness
Most people train pull-ups like they are an endurance exercise.
They are not. At least not at the start.
If you cannot produce enough relative pulling strength to move your own bodyweight, high-rep banded sets and lots of lat pull downs will only take you so far. Until the body can express a high percentage of bodyweight in vertical pulling force, no number of assisted reps will produce a strict rep.
A strict pull-up needs lats, upper back, biceps, forearms, grip, trunk stiffness and scapular control working together. There is nowhere to hide and nothing to push against. If the muscles cannot generate force greater than your bodyweight, the bar will not move.
Before pull-ups become a volume problem, they are a strength problem.
Build the strength first. Then build the reps on top.
Why are pull-ups so hard - the three limiters
Every pull-up is an expression of extreme relative strength.
You are asking the muscles of the upper back, the lats, the biceps, and the forearms to move 100% of your bodyweight against gravity, in a vertical plane, through a full range of motion, with a stable trunk. There is nowhere to hide and nothing to push against. If the muscles cannot generate force greater than your bodyweight, the bar will not move.
Three factors determine how hard a pull-up is for you specifically:
- Mass to strength ratio. A heavier soldier needs to produce more absolute force to clear the bar. This is why two athletes with identical absolute strength can have very different rep maxes - one weighs 80kg and one weighs 95kg.
- Movement efficiency. Stronger people move efficiently. Beginners often initiate the pull from the elbows rather than the scapulae, allow the ribs to flare, and waste energy through poor positioning. The same physical strength gets you fewer reps when it leaks through bad mechanics.
- Tissue capacity. Elbows, shoulders, forearms and hands need time to tolerate repeated hanging and pulling volume. Tendons and connective tissue adapt slowly. Skip this and you turn a strength problem into an injury problem.
Why can't I do a pull-up? The two reasons why most people suck.
Two errors account for the vast majority of stalled pull-up training.
1 - A lack of specificity. Soldiers who want better pull-ups often spend most of their pulling volume on lat pulldowns, cable rows, and band work. These have a place. None of them are pull-ups. The body adapts to the demand placed on it, and the demand of moving your full bodyweight vertically is structurally different from any cable-based movement. If you want better pull-ups, you have to pull yourself up regularly, in some form.
2 - A lack of structure. Sessions are unplanned. Reps are recorded in fits and starts. There is no progression model. Some weeks you do three sets to failure. Other weeks you do six sets of three. The body cannot adapt to a moving target. Without a deliberate weekly volume that progresses over time, improvement is largely accidental.
Fix both and most people can add reps in 8 to 12 weeks. Ignore both and you can spend a year "training pull-ups" without moving the standard or just getting injured and frustrated.
Open chain vs closed chain - a quick note to specificity and why pulldowns don't transfer cleanly
There is a useful distinction worth understanding here. A pull-up is a closed-chain movement. Your hands are fixed on the bar and your body moves through space, much like a push up. A lat pulldown is an open-chain movement. Your body is fixed on the seat and the bar moves through space.
That difference matters more than people give it credit for.
In a closed-chain pull-up, the entire body has to stabilise itself in mid-air. Trunk, glutes, scapulae, grip, and breathing all have to coordinate while the prime movers do their job. In an open-chain pulldown, the seat and thigh pad take care of all of that stabilisation for you. You can produce the same lat force with a fraction of the supporting work.
This is why trainees who can pulldown 100kg often still struggle to do five strict pull-ups. The pulldown built the lat strength and some tissue capacity. It did not build the full-body coordination/timing, scapular control under bodyweight, or the trunk stiffness that a pull-up demands.
Pulldowns have a place as an accessory. They are not a substitute. If you want better pull-ups, the main bulk of training volume has to live on the bar.
Build the platform first: dead hang, active hang, scapular pulls
Before chasing reps, build the platform.
A pull-up is not an arm exercise. It is a coordinated effort that begins at the scapulae, transmits through the lats, and finishes at the elbows. If the scapulae cannot retract and depress under load, the rest of the movement is built on poor foundations.
Three drills belong in every beginner's first six weeks. They are commonly confused, so the distinctions matter. These are three different drills with three different jobs.
Dead hang
If you can’t hang from a bar for 60s how do you expect to do high rep pull-ups?
Hang from the bar with arms straight and body fully relaxed. Shoulders are allowed to elevate up to the ears. Spine and shoulder joints decoapt, meaning the joint surfaces decompress under bodyweight. The lats lengthen passively. Your grip should be pretty much the only thing working hard.
Purpose: Grip and forearm conditioning, joint decompression, and shoulder mobility through gentle distraction. This is not the starting position of a pull-up. It is its own thing, and it is genuinely useful for tactical athletes whose shoulders carry chronic load from packs and body armour.
Goal: 60 seconds of accumulated dead hang per session, broken into 2 to 3 sets if needed.
Active hang
Hang from the bar with arms straight, shoulders depressed and packed, lats engaged, ribs down, core and glutes activated, whole body slightly tensioned. The shoulders are away from the ears. You should feel the lats and upper back working to hold the position.
Purpose: This is the start position of a strict pull-up. Active hangs train postural awareness and the muscular pre-tension that every clean rep starts from. If you cannot hold an active hang, you cannot start a pull-up properly.
Goal: 45-60 seconds of accumulated active hang per session. Positional quality over duration.
Scapular pulls
From an active hang, pull the shoulder blades down further and your sternum up as if initiating the bottom of a pull-up without bending the elbows significantly. The body should rise an inch or two. Hold for a beat, then lower under control to the active hang position.
Purpose: Trains a solid foundation for the initiation pattern of a pull-up. Most beginners try to pull from the biceps. The scapulae should move first. Train the pattern in isolation and the full rep gets cleaner.
Goal: 6 to 8 quality reps per set. 2 to 3 sets per session.
These three drills cost almost nothing in recovery, can be programmed daily, and make every later pull-up rep cleaner once you start adding them.
Daily exposure. Low cost. High return.
How to build your first pull-up: the eccentric rep
If you cannot yet do a single clean pull-up, on of the fastest routes to your first strict rep is the slow eccentric. Also known as the negative.
A negative (or eccentric only) pull-up means starting at the top of the bar (chin over, by jumping or stepping up) and lowering yourself under control back down to a full active hang position. Three to five seconds is a useful starting tempo. Six to 10 seconds becomes the goal once strength builds. You can do 30-60s eccentric reps too but that’s a little overkill, in my experience, for the majority of people.
The reason this works is biological. The body can produce roughly 1.3 to 1.6 times more force eccentrically (lowering) than concentrically (lifting). This means a trainee who cannot yet pull themselves up can, with control, lower themselves slowly through the full range of motion. That eccentric exposure builds the exact tissue strength and tolerance needed to one day reverse the movement.
A simple zero-to-one progression that works for almost everyone:
|
Phase |
Sessions per week |
Per session |
Goal |
|
Weeks 1-3: Foundation |
3 |
3 sets dead hang + 2 sets active hang + 2 sets scapular pulls |
60s accumulated dead hang, smooth, unrushed scap pulls |
|
Weeks 4-7: Eccentrics |
3 |
4-5 sets x 1 negative @ 5-15s descent + active hang holds |
Smooth, controlled descent throughout |
|
Weeks 8-11: Assisted |
3 |
4 sets x 3-5 banded reps with pauses + 1-2 negatives @5-15s |
Reduce band thickness (or placement height) across weeks |
|
Week 12: Test |
1 |
Strict rep attempt - fresh, fully warm |
First strict pull-up |
Table 1. A 12-week build from no pull-ups to a strict first rep, assuming three sessions per week.
This progression is deliberately slow. People who try to compress it tend to stall in their efforts. Two main reasons: one - the elbow, back and shoulder tissues need exposure time, and two; band-assisted work, if introduced too early, conditions the body to expect external help, helps at the wrong part of the lift and rarely transfers cleanly to a strict rep.
How to do more pull-ups when you're stuck at five
For trainees stuck around three to five reps, the problem is now becoming a volume strategy, no longer pure strength.
Most people, on hitting their first few reps, settle into a pattern of doing two or three sets to failure, one to three times a week. This can build short-term strength but caps total weekly volume at a very low number for adaptations. The body adapts to the average weekly load, not the heroic single set with self-aggrandisement post.
The fix is to drop intensity per set and raise total volume over the session. Practical guidance for the 1 to 5 rep bracket:
- Cap reps per set at 50-60% of your max. If your max is 5, do sets of 3. If your max is 3, do sets of 2.
- Add sets (with rest), not reps per set. Five or more sets of two great reps with intention is more useful for progression than two sets of five shoddy ones for most people in this bracket.
- Train pulls 3-5 times per week. Pull-ups, like any neurological skill, respond to frequency. Skill, confidence and tissue tolerance all improve with exposure.
- Hit a weekly target volume. 30-50 quality reps per week is the bracket where most progress happens for someone going from five to ten.
This is uncomfortable for some people because it means stopping sets while reps are still in the tank. That is precisely the point. You are training the movement, not testing it.
Pulling intent: don't just hang there and hope
This is a little-known area that people don't focus on at the start, but the intention of how you attack this movement matters quite a lot. A strict pull-up should not be a slow grind from the start. You need intent to help get it done. Six cues that change the rep quality immediately:
Pull fast, control slow. Start the rep with purpose. Think explosive pull, controlled finish. A slow start makes the rep harder before it has even begun.
Elbows to the floor. Do not just think "chest to bar". Drive your elbows down towards your ribs. This recruits the lats and upper back instead of overloading the biceps.
Start with the upper back. Set the shoulder blades first. Do not turn every rep into a reverse arm curl. The pull is initiated through the scapulae, not the elbows.
Ribs down, body tight. Loose ribs and swinging legs leak force and require you to half ‘reset the movement’ at the bottom. Stay long through your body, braced and controlled. Think of it as a moving plank or hollow body position.
Finish the full rep. Keep aiming to pull your chest through the bar. A lot of reps die because the trainee stops attacking the rep halfway. Chin clearly over the bar, not skimming it.
Control the descent. Lower under control without swinging. The eccentric is not the bit where you fall back to the bottom. Every descent is a free rep of strength work if you treat it that way.
Pull with intent. Finish with control. Repeat clean reps.
Sample pull-up workouts for the 1-5 rep bracket
Four session formats I’ve used with trainees in this bracket. You can inject these into your regular training without too much of a disruption, especially to start with.
Remember, the frequency of vertical pulling at the beginning of your pull-up journey matters a lot more than load and volume, and you'll recover from it generally with no problem.
|
1. EMOM |
Every Minute on the Minute - 10-15 minutes |
|
Work |
Minute 0:00 - 2 strict pull-ups Repeat every minute on the top of the minute for 10 to 15 rounds. Total: 20-30 strict reps in relatively no time. Rest the remainder of each minute. |
|
Why it works |
Caps reps at sub-max, forces frequency, accumulates volume without ever taxing the system to failure. The clock helps to remove decision fatigue and hesitation. |
|
2. Escalating Density Training (EDT) |
1-2 exercises - 12-15 minutes |
|
Work |
Set the clock. Do 2 strict pull-ups (and say 2-4 overhead presses if pairing the exercise) Repeat without resting beyond what is needed for quality of movement. Record total reps. Beat the score in 2 weeks at the same effort. |
|
Why it works |
Builds total weekly pulling volume, ties pull-ups directly to a complementary back exercise or antagonist movement, and creates a clear progression metric. Repeat the session every 7-10 days. |
|
3. Submax AMRAP circuit |
10-15 minute continuous circuit |
|
Work |
2 strict pull-ups 5 push-ups 10 air squats Repeat continuously for the time. Move steadily, not maximally. Aim for 10-20 rounds, totalling 20-40 strict pull-ups. |
|
Why it works |
Keeps pull-up reps sub-maximal across the whole session by spreading them between two recovery exercises. Builds work capacity and pulling volume in parallel. |
|
4. Cluster sets |
3-5 sets of 3-5 rounds of 2-3 reps, with 15 to 20 seconds rest after each round and 2 mins rest after each set |
|
Work |
Pick a structure that hits your volume target for the day. For example, 3 to 5 sets of 3 to 5 rounds of 2 to 3 reps. Do 2 to 3 strict pull-ups, drop off the bar. Rest 10 to 20 seconds, then repeat for the prescribed number of rounds. Rest at least 2 minutes between sets. Scale sets and rounds to your bracket. Progress by adding a rep per round or an extra round over the weeks. |
|
Why it works |
The brief intra-round rest allows partial replenishment of ATP and phosphocreatine between efforts, so reps stay clean and powerful instead of degrading into a fatigued grind. Every rep is trained sub-max and with intent. The volume scales easily. The cleanest way to apply progressive overload to the pull-up itself. |
Stop the sessions if the quality of reps drops. Volume only counts if reps are clean.
Add load carefully: bodyweight is not the finish line
Once you can hit 6 to 8 clean strict reps, adding load is one of the best ways to make bodyweight pull-ups feel easier. A stronger (absolute strength) pull-up makes every bodyweight rep cost less.
But do not rush it. Weighted pull-ups are a strength tool now, not an ego test. They expose elbow tendons to load that bodyweight reps simply cannot.
Earn the right. Add weight only once you can perform 6 to 8 clean strict reps with full range, full lockout at the bottom, chin clearly over the bar, and no kicking or kipping. If the bodyweight rep is messy, the loaded rep will be worse.
Start small. 2.5kg to 5kg is enough. You are trying to build strength, not ruin your elbows or grip. Treat it like any other progression. Adding 10kg straight away is how trainees end up with golfer's elbow that lingers for months.
Keep reps low. Back to using sets of 2 to 4 reps. Weighted pull-ups should stay crisp. If form breaks down in the back end of a set, you are too heavy or too tired.
Progress slowly. Add load only when every rep is controlled from hang to finish. Most people benefit from sitting at a given load for at least 2 to 3 weeks before adding more.
Keep some bodyweight volume in. Heavy work builds strength. Submax bodyweight reps keep the skill and weekly volume alive. Dropping bodyweight pull-ups entirely is a common mistake once load is added.
A soldier who can do twelve strict pull-ups at bodyweight and six clean reps with 10 to 15kg added is physically well-placed for almost any selection test or course.
A note on bands: they help, but they also lie to you
Bands give the most assistance at the bottom of the pull-up. That is usually the mechanically easier part of the movement for most people.
They give the least help near the top, where the pull-up is often hardest, particularly the chin-over-bar or chest-to-bar finish.
The result is a strength curve mismatch. Banded reps can build confidence and volume, but they do not perfectly match the demand of a strict pull-up. The pattern of effort is different.
Used briefly in weeks 8 to 11 of a zero-to-one build, with the band thickness or placement height reduced progressively, bands are useful. Used as the default method of pulling volume for months on end, they hold people back.
Use bands as a bridge. Do not rely on them as a crutch
Accessory work that transfers: more strength as armour
Most pulling accessories without intent becomes somewhat of a ‘junk volume’ pitfall. These three have genuine carry-over to the strict pull-up:
Heavy strict rows. Single-arm dumbbell rows, chest-supported rows, or barbell rows with strict form. Builds big strength in the upper back and arms. Aim for sets in the 4 to 6 rep range with weights that genuinely challenge you. Dumbbells, barbells, cables - the format matters less than the intent.
Paused pulldowns. Pull to the collarbone, hold for 1 to 3 seconds, return under control. The pause exposes the bottom range of the pull, which is where most reps fail on the bar. Cementing that fully scapula depressed range pays off when you return to the bar.
Loaded carries. Farmer's, suitcase, and trap-bar carries strengthen trunk stiffness and grip without adding pulling fatigue. Particularly valuable for tactical athletes who load-carry for a living.
Doing 6 to 10 different pulling variations rotated weekly is not helping. It is just more unfocused noise. Pick the few that earn their place and run them consistently.
Pull-up progression pathway: how frequency, volume and intensity shift over time
The shape of pull-up training changes as the athlete progresses.
Early stage (no strict rep yet). Practice often. Daily exposure to dead hangs, active hangs and scapular pulls is acceptable. Eccentric work 3 sessions per week. Intensity is naturally manageable because no rep is at full bodyweight on the concentric phase.
Middle stage (1 to 8 strict reps). Frequency stays high: 3 to 4 pulling sessions per week. Volume per session is moderate. Intensity per set is deliberately capped at 50 to 60% of max. Total weekly volume is the main driver of progress.
Advanced stage (8+ strict reps, adding load). Frequency can drop slightly to 2 to 3 sessions per week. Specific intensity rises through loaded work. Total volume of strict bodyweight reps stays in the picture to maintain capacity and skill.
At the start, practise often and keep intensity manageable. Once strict reps are available, frequency can drop while intensity and specific volume rise. Total weekly volume should never drop to zero.
How to programme pull-ups into a wider training week
No movement exists in isolation. Pull-ups sit alongside aerobic work, load carriage, and lower body strength training. The mistake to avoid is treating them as an afterthought. Three sets at the end of a session, two days a week, when energy is low.
A practical structure for someone preparing for selection might look like:
Monday. Strength session including 4 sets of strict pull-ups at sub-max effort.
Tuesday. Aerobic or tabbing session. No pulling.
Wednesday. Upper body focussed session. Pull-up EMOM or clusters. 20 to 30 quality reps.
Thursday. Full body strength. Hangs and scapular pulls as accessory work.
Friday. Skill/sprints or technique session. 4 to 5 sets of 2 to 3 reps focused on rep quality.
Saturday. Long aerobic or tab. No pulling.
Sunday. Rest.
Total weekly volume around 35 to 50 strict reps, depending on bracket. The point of this structure is that pull-up volume is distributed across the week, never concentrated in a single ‘hammer the living shit out of myself’ session. Frequency drives adaptation. Single-session intensity drives fatigue.
Grip and hand position
Not all pull-ups are mechanically equal. A wide, pronated (overhand) grip is the hardest variation. It puts the shoulder in a less advantageous position and reduces how much the bigger, stronger muscles can contribute. As you move to a shoulder-width grip, then to a neutral (palms-facing) grip, and finally to a supinated (chin-up) grip, the movement gets progressively easier and allows more contribution from the lats, biceps and forearms.
This matters practically: if you are struggling to get a pronated pull-up at shoulder width, moving to a supinated or semi-supinated position will often get you that first rep, which carries a real psychological benefit as well as a mechanical one. It also means you can move up and down this continuum of mechanical advantage and disadvantage to vary the stimulus throughout your training, which pays off over time.
None of these grips are cheating. They are simply different points on a difficulty scale.
Grip strength as a limiter
For a meaningful number of people, the limiting factor in a vertical pull is not the back, it is the hands. If your grip fails before your lats do, you will never fully load the muscles you are trying to train.
Grip endurance and crushing strength both feed directly into your ability to hang, brace and pull under load. This is exactly why we place so much emphasis on the foundations, whether that is holding a dead hang for a set time or the dedicated grip training that features in every one of our programmes.
5 Common mistakes: why good athletes still stall
Most stalls are caused by avoidable errors. The big ones we find are:
Kipping too early. Momentum hides weakness. It does not build strict strength. Kipping has its place in CrossFit-style metcons, but if your goal is strict reps, train strict reps. Mixed methods slow both.
Failure every session. Testing and pushing to your max too often usually caps progress. Failure sets don’t really have a place in progressive linear training. Done every session, it interferes with recovery and the central nervous system, and progress flattens within a month.
Neglecting the eccentric. Dropping through the last third of the rep or not fully completing a rep leaks adaptation. Soldiers who can pull themselves up but fall the last third of the descent are leaving free strength adaptations on the table. The eccentric is where much of the tissue toughening happens.
Carrying excess bodyweight. Pull-ups are a relative strength exercise. Every unnecessary kilogram increases the work required. Five kilos of excess mass directly translates into harder reps. This does not mean cut weight aggressively (strength suffers in a deficit), but a serving soldier carrying excess mass in a build-up phase will find pull-ups slower to develop than their leaner training partner.
Programme hopping. Pull-ups reward consistency. Most people change the plan before it has time to work. The plan that works is the one you stick to for 10 to 12 weeks. Most stalls are not because the programme was wrong. They are because it was abandoned before it could produce adaptation.
Bottom line
Reliable, repeatable pull-ups are not built through one big session per week. They are built through frequency, structure and patience.
Three principles to take away:
Build the platform first. Dead hangs, active hangs, scapular pulls and slow eccentrics earn their keep. Skip them and every later rep is harder than it needs to be.
Train frequency, not failure. Sub-maximal sets, multiple times per week, beat occasional maximum efforts every time. Stop sets while reps are still in the tank.
Run the plan to completion and trust the process. The body needs 10 to 12 weeks of consistent stimulus before it pays back. Most people do not get the back end of that window. The plan that works is the one you finish.
Pull-ups punish inconsistency. They reward patience. Get the structure right and the reps come.
Pull-up training: frequently asked questions
How long does it take to learn to do a pull-up?
For most people training three sessions per week with structured eccentric and active hang work, a first strict pull-up arrives in 8 to 12 weeks. The exact timeline depends on starting strength, bodyweight, and how disciplined you are with the prerequisites. Compressing the timeline through volume rarely works. The elbow and shoulder tissues need exposure time.
How many pull-ups should I do per week?
For someone going from 1 to 5 reps, 30 to 50 quality strict reps per week is the productive range. For someone going from 5 to 10, raise it to 50 to 80 reps per week, distributed across 3 to 5 sessions. Volume should always be sub-maximal. If you are hitting failure on most sets, you have gone past the useful range.
Should I train pull-ups every day?
You can train pull-up prerequisites (dead hangs, active hangs, scapular pulls) daily. Strict pull-up work itself does not need to be daily. Three to five sessions per week is enough for almost anyone, and more than that interferes with recovery and other training.
Are bands good or bad for building pull-ups?
Bands have a place in the assisted phase of a pull-up build, but they are commonly overused. The problem is that bands give the most assistance at the bottom of the rep, exactly where most failures occur, so the body adapts to expecting help in that range. Use bands briefly in weeks 8 to 11 of a build, reduce thickness progressively, and prioritise eccentrics and partial-range strict work over band volume.
Are pull-ups or chin-ups better?
Pull-ups (overhand grip) bias the lats and upper back and are typically harder. Chin-ups (underhand grip) bring more biceps into the lift and are typically easier by 1 to 3 reps. Both have their place. For selection-relevant standards, train strict pull-ups as your primary lift and use chin-ups as accessory volume.
Does losing weight help with pull-ups?
All else equal, yes. Pull-ups are a relative strength exercise. Every kilogram of bodyweight is mass you have to lift. A soldier carrying 5kg of unnecessary mass will find pull-ups noticeably harder than the same soldier 5kg leaner. That said, do not cut weight aggressively in a strength-building phase. Strength suffers in a meaningful caloric deficit, and you want the build-up phase fed and recovering.
What is a good pull-up standard for selection?
Standards vary by course and role, but a useful internal benchmark for serving operators preparing for selection is twelve strict, full-range, paused pull-ups at bodyweight, plus six clean reps with 10 to 15kg added. Anyone hitting both numbers is operationally well-placed for almost any UK selection test or course.
When should I add weight to my pull-ups?
Once you can produce 6 to 8 clean strict, paused, full-range pull-ups, you have earned the right to add load. Start with 2.5 to 5kg via a dipping belt or weight vest, keep reps in the 2 to 5 range across 3 to 5 sets, and continue strict bodyweight pull-ups at high volume in a separate session for capacity. Progress load only when every rep stays controlled from hang to finish.
Can I build pull-ups without a pull-up bar?
Not effectively. Pull-ups are a specific movement and the body adapts to specificity. Substitutes (table rows, ring rows, lat pulldowns) build relevant supporting strength, but they do not replace the vertical pulling pattern. If you are serious about building pull-ups, find a bar. Door-frame, garage, public park, or gym. And train on it consistently.
The Stoic Conditioning app builds vertical pulling capacity into every operational programme - from the soldier working towards their first rep to the candidate preparing for SF selection volume. The 7-day trial gives you full access to test it out.
