Full range of motion is better than partial reps for hypertrophy

A common training recommendation is that exercises should be performed through a full range of motion rather than partial repetitions to maximize muscle hypertrophy. The claim is that the greater muscle stretch and time under tension from full ROM movements leads to superior muscle growth compared to partial range training at equivalent loads.

Systematic review of 8 studies examining the effects of range of motion on muscle hypertrophy. The majority of evidence favored full ROM over partial ROM for maximizing muscle growth. Performing exercises through a complete range of motion was associated with greater increases in muscle cross-sectional area in most of the included studies.

10-week RCT comparing full and partial squat ROM in trained men. The full ROM group demonstrated significantly greater quadriceps hypertrophy (+7.2% vs +4.8%) and comparable strength gains. The authors concluded that full ROM squats produce superior hypertrophic adaptations in the quadriceps.

RCT comparing partial (at the lengthened position) versus full ROM preacher curls over 8 weeks. Interestingly, training at partial ROM in the stretched position produced similar or even slightly greater biceps hypertrophy compared to full ROM, suggesting that the lengthened portion of the range is the most hypertrophically relevant. This nuances the full ROM recommendation.
