The push-up is another exercise Khalfe recommends beginners learn. "The push-up should be done without the elbow flaring out too much and can be modified by first attempting them against a wall, then on the floor with your knees on the ground, then progressing into your normal push-up position," he said. Be sure to keep your body in a straight line, avoiding any arching or rounding of the spine.
- 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.
- If this is too difficult, do this exercise with your knees on the floor.
