Rear foot elevated Split Squat

From a standing position, take a long step forwards as if performing a lunge. The heel of your back foot should be raised. Keeping your torso straight, lower slowly until your back knee almost touches the floor, then push back up. Complete all your reps on one leg, then switch to the other. Keep your knees in line with your toes, especially on the front leg, and don’t let the front knee stray past your foot as you lower.
