Enjoy this Core Challenge Workout with Samantha Clayton

再生時間: 7:03 2020/09/25

This beginner ab workout is fast and effective and uses creative interval timing to give you an added challenge. This core crunch routine puts an extra emphasis on the rectus abdominal muscles (6-pack muscles) at the front of the tummy but finishes up with exercises for the sides and back stabilizing muscles too. This is a well rounded core routine.
