- Stand with your feet together and the ball of your right foot on a slider.
- Take a controlled lunge (or large step) backward with your right foot, keeping that leg straight and dragging the slider behind you as you reach your arms to the floor in front of you (like you would in a single-leg deadlift).
- Keep your left knee bent; then with control, bring your right leg back to your starting position with your chest and arms up.
- Do eight to 12 reps, then repeat on the other side.
Note: The first variation in Megan's video is the back lunge reaches.
