Instructions

Grasp a dumbbell in each hand and hold them by the sides of your body with your arms straight. Position your feet so that they are a fist distance apart. Take a large step forward with one leg, and position your back foot so that your heel is up. Lower body by flexing the knee and hip of both legs. Keep lowering until your back knee is almost touching the floor. At the bottom of the lunge, your legs should both be in a 90 degree angle. Return to original standing position by forcibly extending the knee and hip of the front leg. Repeat with other leg.
