Doing certain types of leg exercises that don't go through the full movement might build more muscle near the knee than doing the same exercises through the full motion.

Doing a full squat or starting a bicep curl from the bottom makes your muscles grow more at the far ends (like the top of your thigh or the outer part of your bicep) than doing partial reps from the top.

Doing full squats or full arm movements when lifting weights doesn’t necessarily make your thigh muscles grow bigger than doing partial movements—studies show both ways work about the same, so going all the way down or all the way up might not give you extra muscle gains.

Doing only the bottom part of an exercise (where the muscle is stretched) can build as much muscle in your arms and legs as doing the full movement, as long as you put in the same amount of effort and work.

Training muscles through a full range of motion or lengthened partials produces greater hypertrophy than training through shortened partials, particularly in distal muscle regions.

Muscles don’t grow evenly — some parts get bigger than others, and different muscles in the thigh respond differently to the same exercise.
