This video starts off with a guy doing several one-arm push-ups. He goes on by saying that since the days of rocky a lot of men have wanted to do the one arm push up. It takes a long time to develop the strength needed to be able to do the one arm push-up set. The video demonstrates a way to be able and start doing them now with the assistance of a power stretch band. Have the band tried up high and wrap the loop around the shoulder that you will not be using in the one arm push up. Press your body up and down, you should be able to do several repetitions with the help of the band. It's also good to maintain a wide base with your feet to keep balance.
