Push-ups are my favorite upper body exercise because they're so effective. They're challenging to do with both knees off the floor, though, so here's an easier variation. Not only will you work your chest, shoulders, and upper back, but holding one leg up targets your booty and hamstrings as well.
- Come onto your hands and knees, so your shoulders are above your wrists, and your hips are above your knees.
- Extend your right leg straight behind you so it's parallel with the floor. Engage your abs and try to keep your heel in line with your hips.
- Now do a push-up, by bending your elbows by your sides as you lower your torso down toward the ground. Then straighten your arms pushing yourself back up into place.
- Repeat for a total of 20 to 30 push-ups, maintaining steadiness and control, keeping your abs and back strong, and continuing to extend your right leg straight out.
- For your second set, switch legs so your right knee is on the floor and your left leg is extended to the back. Do 20 to 30 push-ups on this side.
