Pushups is your starting point and your hands are white on the outside of your shoulders on a brace,
the belly, your body weight forward so that you have your hands and your shoulders at the same level,
you can do it on your knees.
You can do it on your toes.
It doesn't matter what you do, makes you breathe.
You have more the body.
You want to bring a chest down to the elbows level and then push all the way up, down and up movement.
