If you want to improve your upper-body strength, you can't skip out on the push-ups. Here's a simple trainer tip for mastering the push-up once and for all.
- Start in a plank position, with palms spread out evenly and your shoulders over your wrists and legs out behind you. Pull your belly button in, and keep your back straight.
- As you lower and exhale, bend your elbows outward to the sides. Hold at the bottom before you raise back up to complete one rep.
