Modified Push Up
This gentle modification decreases the weight supported by the upper body during this classic move to strengthen your chest, shoulders, back and core.
With palms facing down, sit up on your knees and hands so that your arms are fully extended and shoulder width apart, your knees and feet are on the floor.
Make one line from your knees to your head.
Bend your elbows and lower your upper body to the floor. Repeat for the desired number of reps.
