Doing leg extensions makes the front thigh muscle grow more evenly along its length than doing squats, which don’t stimulate that muscle as much.

The study found that leg extensions made the front thigh muscle grow more than squats did, at every part of the muscle, which is exactly what the claim says.

Doing leg extensions makes the front thigh muscle bigger along its whole length more than doing squats, especially near the knee.

Doing leg extensions for 8 weeks makes the front thigh muscle bigger along its whole length more than doing squats, especially near the knee.

Which leg exercise you choose matters: leg extensions grow the front thigh muscle more, squats grow the lower outer thigh more and make you stronger at squats—but both help you get stronger at leg extensions.

89%

Different leg exercises make different parts of your thigh muscles bigger — leg extensions grow the front part, squats grow the lower outer part.

87%

Doing leg extensions (kicking your leg out while sitting) makes the front thigh muscle right above your knee grow more than doing leg presses (pushing a heavy platform with both legs).
