Pushups

The pushup is a closed-chain bodyweight pressing exercise performed in a prone plank position. It is the most accessible upper-body pressing movement, requiring no equipment and supporting approximately 68% of total bodyweight through the hands. EMG analysis confirms the pushup elicits pectoralis major activation (95–105% MVIC) comparable to a bench press loaded at approximately 60% of 1RM — making it a meaningful training stimulus across a wide range of populations.

Execution

1. Place hands slightly wider than shoulder-width; fingers pointing forward or 15° outward
2. Set a rigid plank from head to heel — no hip sag or pike; brace the core throughout
3. Lower the chest toward the floor with elbows at 45–70° from the torso (not fully flared)
4. Touch or approach the floor; pause briefly
5. Press through both hands simultaneously until the elbows are straight; actively protract (push) the scapulae at the top

What the EMG Data Shows

Pectoralis major (95–105% MVIC): Standard pushups produce near-maximal pec activation despite supporting only 68% of bodyweight. This is equivalent to a bench press loaded at ~60% 1RM — the pec is under significant loading without requiring external load.

Triceps brachii (73–109% MVIC): The wide range reflects variation in hand width and execution. Diamond pushups (hands close under chest) push triceps activation toward the upper end; standard pushups cluster in the mid-range.

Serratus anterior (67–87% MVIC): This is the pushup's differentiating feature from the bench press. The bench press pins the scapulae to the pad, suppressing serratus anterior activity. The pushup requires active scapular protraction throughout, generating substantial serratus activation — a major contributor to serratus health and long thoracic nerve function. The pushup is the primary exercise prescribed for serratus anterior strengthening in rehabilitation.

Diamond pushup superiority: The diamond (triangle) hand position produces the highest relative EMG for both the pectoralis major and triceps brachii across all hand widths, making it the most demanding standard-surface pushup variation.

The Scapular Advantage

The pushup's key mechanical distinction from all forms of bench pressing is scapular freedom. Because the chest is not anchored to a pad, the scapulothoracic joint can move through full protraction and retraction throughout each rep. This creates:

1. Active serratus anterior strengthening (67–87% MVIC) — unavailable in the bench press
2. Natural scapulohumeral rhythm — the glenohumeral joint is not exposed to impingement positions created by forcible scapular pinning
3. Core demand — the entire chain from feet to hands must remain rigid, unlike the supine bench position

For populations prioritizing shoulder health over maximum load, the pushup is often superior to the bench press despite lower absolute loading.

Variations

Variation	Key difference	Best for
Diamond pushup	Narrow hands; highest triceps and pec EMG	Triceps emphasis; maximum bodyweight pressing demand
Wide pushup	>shoulder width hands; greater pec horizontal adduction	Pec major width emphasis
Pushup on rings/TRX	Unstable; significantly increases pec and core activation	Pec emphasis; serratus and shoulder stabilizer demand
Archer pushup	Asymmetric; loads one arm progressively	Progression toward one-arm pushup
