Lie prone with your arms straight, your palms flat on the floor, and your hands shoulder width apart (or wider). Place your feet together, heels touching.
1. Inhale and bend your elbows to bring your torso near the floor; avoid extreme hyperextension of your spine.
2. Push yourself back up until your arms are in an extended position. Exhaling as you complete the movement. Repeat the next push up.
Notes:
You can do this exercise anywhere, especially while traveling. It is excellent for developing the pectoralis major and the triceps.
You can vary the torso to isolate the work, i.e., elevate the feet to focus on the upper pectorals, and elevate the torso to focus on the lower pectorals.
