Bridge

The basic bridge strengthens your glutes (butt) and hamstrings (back of the thigh) while enhancing core stability. It's easy to add into a strength training workout, can be used as a warm-up, and is even a good rehab exercise for improving core and spinal stabilization.

1. Find an open space on the floor and lie on your back, using a mat if you have one. Rest your hands at your sides, bend your knees, and place your feet flat on the floor, beneath your knees.

2. Tighten your abdominal and buttock muscles by pushing your low back into the ground.

3. Raise your hips to create a straight line from your knees to your shoulders.

4. Squeeze your core and pull your belly button back toward your spine.

5. Hold for 20 to 30 seconds.

6. Lower the hips to return to the starting position.
