Doing exercises through a full motion or starting the movement with a shorter motion (but not ending with it) helps your muscles grow more in your thighs and biceps than doing only the last part of the movement.

Doing exercises through a full motion or starting the movement with a shorter motion (but not ending with it) helps your muscles grow more in your thighs and biceps than doing only the last part of the movement.

If you only do the first half of a leg extension, your upper thigh muscle grows more than if you do the full motion.

If you're a young woman just starting to lift weights, doing exercises through certain parts of the movement — like the top half or the full motion — helps your leg muscles grow more than doing just the bottom part. Not all shortcuts in the exercise are equally good for building muscle.

When you squat or move your legs wide, using a full motion helps your butt and inner thighs grow more than only doing the top half of the movement.

When you do full-range exercises like deep squats, some leg muscles like your inner thighs and butt grow more than others, but your front thigh muscles don’t seem to care whether you go deep or not — not all muscles react the same way to how far you move.
