Why a Letter I Press Up works:
Letter I Press up works so well because all the weight of your body is being held up by your shoulder muscles.
Ideally, try to keep your body as straight as you can. This will be difficult but is something to work toward. You can develop shoulder problems quickly with this exercise so be careful with it.
Breath out as your push away from the ground. Breath in as you lower yourself down.
