This is a quick core workout designed to attack your upper and outer ab layers (rectus abdominus & external obliques). If you challenge yourself to do at least 5 reps of each core exercise, you will have completed over 150 core contraptions in 15 min -- totally doable! Remember to exhale as you contract your ab muscles during each rep.
