If you're already someone who lifts weights, doing either static holds with your muscles stretched out or full-range weight exercises won't make the outer part of your thigh noticeably bigger in just six weeks.

Doing static leg exercises with your thigh muscles fully stretched might grow the upper part of your thigh more than doing regular leg exercises that move through a full range, but both types of exercise end up making your whole quadriceps muscle about the same size.

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.

If you train your quads using either holding a static position with your legs stretched out or doing full squat-like movements, both ways build your thigh muscles about the same amount — neither one is better than the other.

The lower part of your thigh doesn’t grow as much from weight training as the upper and middle parts—even if you train hard and use fancy techniques.

You don’t need to train every day—just twice a week for two months can make your upper and middle thighs bigger, as long as you do enough total work.
