What it works: Glutes, thighs and core
A. Stand with your feet together, hands on your hips or behind your head.
B. Step forward with the right leg. Bend both knees and begin lowering yourself until the front thigh is parallel with the ground and the left knee is almost touching the ground. Both legs should create 90-degree angles at the knee. Your torso should be straight up and down, not bent over.
C. Keeping an even weight distribution on both feet, return to starting position and alternate legs.
Make it harder: Try holding dumbbells at your sides or on your shoulders.
