When comparing hip thrusts and squats at the same effort level, the front thigh muscle (quadriceps) works just as hard in both exercises.

Similar Assertions

When doing a hip thrust with a barbell instead of a squat, the butt and back of the thighs light up more on muscle sensors during the same level of effort.

93%

When trained women lift heavy weights, thrusting the hips up with a barbell turns on the butt and hamstring muscles way more than doing a squat, but the front thigh muscle works about the same in both exercises.

85%

When women who lift weights do squats with a really heavy weight (close to their max), their leg and butt muscles have to work a lot harder than when they use lighter weights.

80%

For women who lift weights regularly, squatting with 80% or 90% of your max weight activates your muscles about the same — going heavier doesn’t seem to turn on more muscle once you hit that range.

77%

Doing hip thrusts or squats for 9 weeks with the same total work builds your butt muscles just as much, even though hip thrusts feel like they work your butt harder during the exercise.
