Get ready to work your core in just under 13 minutes in this short workout. You will strengthen all of the different muscle layers of the abs, while also mobilizing the lower back. When the abs contract during the exercises, so do the deep muscles on both sides of the spine, acting like a powerlifter belt around the area. This cooperation between the muscles in the front and back is vital in keeping an upright posture and preventing lower back pain as well, so regular practice is highly recommended. I hope you enjoy the class!
