Start on your back with your knees bent and your feet hip distance apart with a dumbbell in each hand. Hold the weights by your chest.
Squeeze your glutes as you push your pelvis toward the ceiling, coming into a bridge. Keep your ribs aligned with your pelvis. Your spine should be in a neutral position, meaning there is no arching or curving of the spine.
Holding the bridge, press the weights to the ceiling directly above your shoulders, then lower back down with control. Be sure to keep maintain a strong bridge position the entire time. This counts as one rep.
Perform this exercise for 40 seconds, then take 20 seconds of rest.
