Start by placing your hands flat on the ground at just wider than shoulder width, your hands should be directly in line with your shoulders. With your knees bent at roughly 90 degrees space them to be approximately hip width.
With your arms almost fully extended, lower yourself by bending the elbows until your elbows reach a 90 degree bend. Then push back up by driving through your palms until your arms are back at the starting position. Your elbows should be pointed outwards at roughly 45 degrees throughout the movement. Keep your core and glutes activated at all times to maintain a straight back. Conduct the movement in a slow and controlled manner for the desired amount of repetitions.
Avoid flaring the elbows out too far where they are out near the shoulder and conduct the movement without arching your back too much.
