The most common objection to training one exercise per session is that it produces an imbalanced physique. The Push Pull Squat rule disposes of that concern in three words.
Ultra-abbreviated training asks a question that most gym trainees find genuinely uncomfortable. What if less is not merely sufficient — what if less is actually better? Not one exercise fewer than usual. Not a slightly shorter session. One exercise per workout, performed with full intent, full recovery, and nothing else.
The objection arrives immediately. Won't that produce an imbalanced physique? Won't important muscle groups be neglected? Won't the programme eventually become so narrow that it fails to develop the body completely? These are reasonable concerns. They are also concerns that a single governing principle resolves entirely — one that has guided serious single-exercise trainees from William Boone in the 1930s through Brooks Kubik's Dinosaur Training to the practitioners applying it today.
The principle is the Push Pull Squat rule. And it is simpler than most training theories have any right to be.
The human body moves in three fundamental patterns that resistance training needs to address — pushing, pulling, and squatting. Every major muscle group belongs to at least one of these categories. The chest, shoulders, and triceps are push muscles. The back, biceps, and rear deltoids are pull muscles. The quadriceps, hamstrings, glutes, and lower back are primarily developed through squat and hip hinge patterns. A programme that includes one variation of each across a training week addresses the entire body — regardless of how abbreviated that programme is.
This is the Push Pull Squat rule. It does not specify which push, pull, or squat variation to use. It does not prescribe sets, reps, or frequency. It simply states that over any reasonable training period — a week, a month, a six-week block — all three patterns should appear. Apply this rule to a one-exercise-per-session programme and the balance concern dissolves entirely.
One exercise from each category across a training period is genuinely sufficient to address every major muscle group the body contains.
Bench press, overhead press, dips, push-ups. Any movement that presses a load away from the body against gravity.
Deadlift, bent-over row, chin-up, pull-up. Any movement that draws a load toward the body or raises the body toward a fixed point.
Barbell squat, front squat, hex bar squat, Romanian deadlift. Any movement that drives through hip and knee extension under load.
The rule can be applied in two ways. The trainee who prefers training all three patterns each session performs one push, one pull, and one squat movement per workout — an approach covered in detail on the Ultra Abbreviated Training page. The trainee who prefers single-exercise sessions takes a different approach — one exercise per session, rotating through push, pull, and squat across separate workouts. The Push Pull Squat rule governs both. Balance is achieved across the rotation rather than within each session.
Push, pull, squat. Three movements. The entire body covered. This is the structural logic at the heart of the Minimum Effective Strength System — applied across five specific movements rather than three, but governed by exactly the same principle.
The one-exercise workout approach produces two natural programme structures depending on how many exercises the trainee wants to rotate across and how long they want to specialise on each. Both apply the Push Pull Squat rule. Both ensure balance across the full training period. And both look so minimal on paper that it takes genuine experience — or the historical examples of the men who used them — to appreciate what they produce.
Six weeks of dedicated specialisation on each of three movements. One session per week per exercise. One exercise per session.
One session per week. Full focus, full effort, progressive loading. Nothing else. The legs, glutes, and lower back receive the concentrated development that comes from specialisation rather than shared sessions.
One session per week. The chest, shoulders, and triceps now receive the same concentrated focus the legs received across the first six weeks. Strength built in the squat phase carries over systemically.
One session per week. The back, biceps, and rear deltoids complete the rotation. After 18 weeks all three patterns have received six weeks of dedicated specialisation — and the Push Pull Squat balance has been achieved across the full period.
Tony Pandolfo's two-movement insight applied as a complete 12-week structure. Dead simple. Devastatingly effective.
One session per week. The deadlift covers both the pull pattern and the squat pattern simultaneously — developing the entire posterior chain, the back, and the grip in a single movement. As Tony Pandolfo observed: work the heck out of the deadlift and you get growth in the upper and lower back, thighs, and hips.
One session per week. The upper body pressing pattern completes what the deadlift phase began. Six weeks of bench specialisation after six weeks of deadlift specialisation addresses every major muscle group — and does it in twelve weeks of single-exercise training.
Both programmes look underwhelming written on paper. One exercise per week for six weeks before moving on seems impossibly minimal to anyone conditioned by conventional training culture. The question to ask is not whether it looks impressive — but whether, when the load is progressively increased across every session of every six-week block, the cumulative effect is significant. The answer, as William Boone and every subsequent single-exercise practitioner has demonstrated, is emphatically yes.
If you are not gaining, always do less — not more. Less volume. Less frequency. More intensity. This is not rocket science.
Arthur Jones — founder of High Intensity TrainingThe one-exercise workout is not a programme for people who lack the time or motivation to train properly. It is a programme for trainees who have understood something that most gym culture never reaches — that the quality and focus of each individual session matters far more than the number of exercises it contains, and that the progressive loading applied to a single movement across weeks and months produces results that scattered effort across many movements rarely approaches.
The Push Pull Squat rule keeps the one-exercise approach honest. It prevents the natural drift toward favourite movements and the neglect of demanding ones. It ensures that across any training period, every major pattern receives the dedicated attention it requires. And it does all of this with a simplicity that the fitness industry, which profits from complexity, has little interest in promoting.
William Boone built world-class strength one exercise at a time. Brooks Kubik codified the approach for the modern trainee. Tony Pandolfo reduced it to two exercises and said everything that needed saying. Arthur Jones provided the correction principle that keeps it working indefinitely. The one-exercise workout has a lineage that stretches back nearly a century and forward into any training programme serious enough to apply it.
One exercise workouts — it really is amazing what you can achieve with dedicated hard work and a handful of basic movements.
Push. Pull. Squat. Three patterns. Five movements. The Minimum Effective Strength System — the programme that takes the Push Pull Squat rule and builds a complete, balanced, progressive system around it.
