Step-by-step instructions

1. Lie face up on the floor, with knees bent 90 degrees and feet flat on the floor. Squeeze a rolled-up towel between your knees.
2. Bridge hips toward the ceiling by squeezing your glutes. Only your shoulders and heels remain on the ground. Hold, then lower the hips to the ground without touching the floor. That's one rep.
