The bridge is a strength exercise for your core muscles. It involves lifting your hips off the floor and holding this pose for a one count or more. You do not need any extra equipment for the bridge exercise, but you can use balance equipment to make it more challenging.
To do the basic bridge pose, lie on your back with your knees bent and your feet flat on the floor about hip-width apart. Relax your arms next to your sides. Exhale and lift your hips off the floor until your body is a straight line from your knees to your shoulders. Your hamstrings and gluteus muscles are the main movers as you lift your hips off the floor. Squeeze your buttocks and pull your belly button toward your spine to activate your abdominal muscles. Hold this pose for a one count and lower your hips back to the floor.
The bridge exercise targets your core muscles, which includes your abdominal muscles -- rectus abdominis and transverse abdominis -- and your low back and gluteus muscles. In addition to your core muscles, the bridge exercise works your hamstrings, the muscles on the back of your thighs. Some bridge exercise variations also target your quadriceps, the muscles on the front of your thighs.
After you lift your hips off the floor, extend one leg into the air for a count. This engages the quadriceps muscles and enhances the balance challenge. The more difficult the balance challenge is, the harder your abdominal and low back muscles work to stabilize your body in the bridge pose. You can also place your feet on an unstable surface, such as a stability ball, to increase the balance challenge. Hold one leg tucked in to your chest to do a single-leg bridge exercise. This increases the work of your hamstring muscles since only one leg is pressing your entire torso. Performing a single-leg bridge on a stability ball is an advanced bridge exercise that requires high levels of strength, balance and flexibility.
When you lift your hips, do not lift them so high that your back arches. Keep your body in a straight line. Engaging your glute muscles relieves some of the tension from your lower back muscles. Perform the bridge as a continuous movement, or hold the pose for extended periods of five seconds or more. Your abdominal muscles and low back muscles isometrically contract -- contract without significant movement -- to hold your hips up in the bridge pose. Remember to keep breathing normally if you hold the pose for an extended period.
