Get inside a resistance band, feet pointing forward at about shoulder-width distance apart, and pull the band to create as much tension as you can handle. Leep a slight bend at the waist and knees (don’t lock your whole body).
Step to your left, and then step your trailing foot. Make sure you don’t drag that trailing foot along the floor. The goal is to walk like this until you reach a certain number of reps or a certain distance.
TIP: Drive each step with your outer thighs (abductors). If these muscles are weak, you’ll feel your glutes helping. This is normal. Try to keep your toes pointing forward to keep the muscle continually engaged; turning your toes out (like a penguin) will switch the abductors off.
