Start on your knees with your hands placed close together under your chest, forming a diamond shape by touching your thumbs and index fingers. Keep your core engaged and your body in a straight line from head to knees. Bend your elbows to lower your chest toward the ground, then push back up to the starting position. Perform reps with controlled movement while maintaining proper alignment.
Log your diamond push up (on knees) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
