Kneel on the ground as you hold a Resistance Band with both hands behind your back. Lean forwards as you normally would to get into a Push-Up position, with your hands at about shoulder width apart. Make sure the Resistance Band is well positioned on your Upper Back.
Your body should remain on a straight line during the full rep by engaging a Posterior Pelvic Tilt (Tuck your tailbone, eliminate any arch in your back) and slightly protract your scapulas.
Perform Push-Ups as usual with the added band resistance until the rep goal is completed.
Kneel back up and let go of the band to complete a full set.
It is recommended to use a hard enough Resistance Band to make sure you're doing your best in every set.
