For strong, lean legs, go beyond aÂ standard body weight squat and try using weights, like in this move from E! host Maria Menounosâ circuit workout.
Here's how to do it: Stand with feet hip-width apart, a 5-pound dumbbell in each hand, raised to your shoulders. Pushing your butt back, lower into a squat. With abs tight, shoulders back, and glutes engaged, slowly rise to standing. Do 25 reps.
