Glute Kickback

Kneel on the floor or an exercise mat and bend at the waist with your arms extended in front of you (perpendicular to the torso) in order to get into a kneeling push-up position but with the arms spaced at shoulder width. Your head should be looking forward and the bend of the knees should create a 90-degree angle between the hamstrings and the calves. As you exhale, lift up your right leg until the hamstrings are in line with the back while maintaining the 90-degree angle bend.
