If you jump from a springboard, you will likely only have to focus more on moving forward in your jump. Ending4: Hold your arms out to either side of your body as you jump, making sure you stay off balance. Walk up to three feet between yourself and the bar so you land lightly and keep your feet and head on the bar as you jump.
