When people lift weights through a full motion vs. just part of the motion, the muscles might look like they grow more in one case—but that could just be because the weight feels heavier at different...

Even if you don’t move through the full range, doing the exercise where your muscle is stretched the most (like halfway down in a squat) builds more muscle than doing it where the muscle is bunched up (like a shallow squat).

Not all muscles grow the same way when you move through different ranges—some might need bigger movements than others. So, telling everyone to do the same type of lift might not work for every muscle.

Doing partial-range weight exercises with a longer muscle stretch can build arm and thigh muscles just as well as doing full-range exercises, as long as you’ve been training for a while and do it for 12 weeks.

When resistance is applied such that peak torque occurs at either the longest or shortest muscle length during a movement with identical total range of motion, muscle hypertrophy is not significantly different between conditions.

If you're already strength-trained and do upper-body workouts for 8 weeks, it doesn't matter much if you lift all the way up and down or just do part of the motion—your muscles grow and get stronger about the same either way.
