DESCRIPTIONPlace one hand on the floor directly under your shoulder, with your arm fully extended, body straight, and toes also on the floor. Spread your feet wide enough to allow you to balance throughout the movement. The closer your feet are together, the harder the exercise and the more your core muscles have to work to stabilize your body.
Inhale as you lower your body towards the floor until your chest is almost touching the ground. Exhale as you push yourself back up until your arms are fully extended.
Be sure to keep your body straight so you don't stick your butt up or let your hips sag down.
