Reverse Lunge

How to do it

1. Stand tall with your feet hip-width apart and your arms relaxed at your sides.
2. Step one foot back about two feet, onto the ball of that foot, and lower straight down until the back knee is just above the floor. Keep the front shin upright and your torso tall.
3. Push through the front foot to bring the back foot forward and stand up.
4. Repeat with the other leg.
