Deficit Reverse Lunge

The deficit reverse lunge is a reverse lunge performed with the front foot raised on a platform, which lets the rear knee travel below the level of the front foot. That extra depth is the whole point: the front leg's glute and hamstring reach a longer stretched position than a floor lunge allows, and training a muscle at long lengths is one of the more reliable ways to make it grow. Stepping backward rather than forward keeps the shin more vertical and is generally kinder to the knee, which makes this a good choice for people who find forward lunges uncomfortable. Start with a low platform, since the range increases fast and balance gets harder with height. Keep the front knee stacked over the ankle and drive back up through the front heel rather than pushing off the rear foot.
