Reverse Lunge W Curl

Start with matching dumbbells and a straight spine and tight core. Step back on one leg as you hammer curl the weights, then alternate to the other leg. Make sure you fire the front leg hamstring as you come out of the lunge. This can be done quite fast with light to moderate weights to increase cardio demand.

Reverse lunges put less stress on the knee than a forward lunge. This can also be done super slow to increase intensity, but not cardio.
