Back to the celebrity butt and legs workout — this is total body workout but I stress mainly on buttocks and because exercising buttocks means to do lots of squat variants this is also workout for legs (thighs). (women-workout-routines.com)
Some workouts do include lots of squats and lunges which build muscle in your quads and can make your legs bigger and more muscly. (rachaelattard.com)
There are lots of squat variations (like sumo squats, narrow squats, split squats, pistol squats, etc.), which are mostly derived from different stances. (neatstrength.com)
