Bridges

Once you feel like you can do pelvic tilts comfortably and consistently, then try to add bridges. With this exercise, you will want to keep your abdominals tight in the pelvic tilt, then squeeze your gluteals (butt) muscles together. Tighten and try to lift up off of the ground.

The gluts help with the extensors as the other part of the core. Again, it may be a small movement and it may be training the brain first how to just turn all of these muscles on together before you start moving your body.

When you have more strength, you can try to lift the hips higher off of the ground, concentrating on keeping the gluts contracted for the whole lift. You may notice other muscles take over, and the glut contraction lessens. If this happens, then do not go as high. Make sure your form is correct before you progress the number of repetitions or add any height.
