If performing these glute bridges on one leg is too difficult, do them with both feet planted on the floor.
- Lie face-up on a mat with both legs bent and feet planted on the floor. Place your hands on the floor beside you for stability. Lift the left leg a few inches off the mat.
- Press your right foot into the floor and squeeze your glutes to lift your hips off the floor, keeping your left leg straight.
- Pause when your body forms a straight line from your shoulders to your knee.
- Slowly lower your hips to the floor. That's one rep.
- Do four sets of 12 reps on each leg.
