There are four good exercises here for your lower back.

In the first one, come up on the exhale and relax down on the inhale.

In the second exercise, the spinal twist, it is tempting to let your top knee slide back and away from your lower knee. Don’t allow it. keep the knees right on top of each other. That will keep the lower back stable.

The third exercise is cat – cow. Inhale when you are looking up and exhale when you push your back up to the ceiling. Also, when looking up, do not let your abdomen drop. Keep some firmness there to support your spine.

In the last one, drop your heels as Carmen shows. This is more of a calf stretch.

Enjoy!
