Stand with your torso upright holding two dumbbells in your hands by your sides.
In preparation to step backward, slowly lift one foot off the floor and find your balance on the standing leg. Try not to move the standing foot and maintain balance. Hold this position briefly before stepping backward. The raised foot should land on the toes first. Slowly shift your body weight onto the lead foot, placing it firmly on the floor.
Inhale and lower your upper body down, while keeping the torso upright and maintaining balance. Do not allow your knee to go forward beyond your toes as you come down, as this will put more stress on the knee. Keep your front shin perpendicular to the ground.
