Walking backwards works all the same muscles as walking forward, but in a different order. It opens up the hip flexors, which tighten during a swing. When walking backwards, stand erect and reach back with your toe hitting the ground first. Squeeze each buttock as the same leg reaches back. Try walking backwards on a treadmill approximately 2.0 mph. With the help of a buddy, try walking backward on a wide path or street. Use the arms as you would when walking forward. Try walking backward for 2-3 minutes at a time switching it with forward walking.
