A No-Equipment Back and Core Strength Workout

Stand with your feet hip-width apart and core engaged. Do a squat, sending your hips back, bending both knees and bringing your thighs about parallel to the floor.

From this squat position, step your right foot forward, then your left foot forward. Now stand.

Squat again, and this time step back with your left foot first, followed by your right foot, so you return to your starting spot. Now stand.

Continue to repeat this pattern, squatting and walking forward to stand. Then squat and walk backward to stand. At the halfway point, switch the foot you typically lead with. (If you’ve always taken the first step with your right foot, try to take the first step with your left foot, so both sides stay even.)
