Find a step, chair, or bench that when you place your foot on it, your knee bends to a 90-degree angle. The weight benches or plyo boxes are often the right height, but a dining room chair can work too for an at-home strength-training session.

1. To start, place your entire right foot onto the bench or chair. Press through your right heel as you step onto the bench, bringing your left foot to meet your left so you are standing on the bench.
2. Return to the starting position by stepping down with the right foot, then the left so both feet are on the floor.
3. Complete 15 steps leading with the right foot, then repeat another 15 steps leading with your left foot. Do three sets. For an extra challenge add a dumbbell in each hand.
