40-Minute Do-Anywhere Bodyweight Circuit

Reps: 20, alternating sides

• Stand with your feet shoulder-width apart, feet parallel. Bend your knees, lowering your hips deeply so your thighs are parallel with the floor, keeping weight back in your heels.
• Rise back up, straightening the legs completely, and lift the right leg out to the side, squeezing the outer glute.
• Lower the right leg to complete one rep; repeat the squat again lifting the left leg as you stand.
• Do 20 reps, alternating sides.

This squat variation tones and sculpts the butt from all angles — plus standing on one leg fires up your core.
