Stand with your feet together, arms at your sides. Bend over (its OK for your knees to be slightly bent) and place your hands or fingertips on the floor in front of you. Walk your hands forward until you are in a pushup position and do one pushup. Keeping your hands in place, walk your feet forward until theyre as close to your hands as possible. Thats one rep. Continue moving forward until youve done five or six pushups.
