How to do Reverse lunges
Begin standing with the feet together and your hands on your hips.
With one foot, take a large step backward as you lunge down bringing the back knee down toward the ground. At the same time, lean your torso forward slightly.
Once the back knee is about an inch off the ground, reverse the motion as you shift your weight toward the front leg and stand back upright with the feet together again.
Repeat for the desired repetitions, alternating legs.
