1. Lie faceup on the floor and pull your left knee up to your chest. Hug your shin.
2. Bend the right leg and plant your foot on the floor close to your butt.
3. Drive through the middle of your foot and squeeze your glutes as you bridge your hips up—they won’t go high—until your hamstrings start to tense. You want to keep the tension on your glutes instead.
