How to Firm hamstrings and glutes with a walking lunge
If you can walk, then you can do this exercise. Many exercise moves force you to contort your body like a German pretzel, often resulting in tilting over in a ball of confusion before the lifting or the squating even begin.
This walking lunge move, however, is as simple as it gets. You walk, lunge, then repeat. Try doing it outdoors at a park so you can keep going without turning around.
