A basic push-up, with the hands directly under the shoulders, is a challenge all on its own. Whether you do it with straight legs or knees on the floor, you'll strengthen and tone the muscles in your arms, upper back, and core.
- Start in a plank position with your arms and legs straight, shoulders above your wrists.
- Take a breath in, and as you exhale, bend your elbows out to the sides and lower your chest toward the ground. Stop as soon as your shoulders are in line with your elbows. Inhale to straighten your arms.
- This counts as one rep. Complete 10 reps.
- If this is too difficult, do this exercise with your knees on the floor.
