Does squatting shallow or deep make your thighs bigger?
Knee flexion range of motion does not influence muscle hypertrophy of the quadriceps femoris during leg press training in resistance-trained individuals

People who already lift weights did leg presses for 8 weeks, using either a shallow knee bend or their deepest possible bend — one leg did each.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

In people who already train regularly, 8 weeks of weight training causes a small increase in muscle size that is often too small to measure reliably, making it hard to tell which training methods are better.
Among people who regularly train with weights, limiting the knee bend during leg presses to a smaller range produces the same increase in quadriceps muscle thickness as using a full range of motion over eight weeks.
