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.
No equipment needed, either, but you may want an exercise mat to protect your back and toosh!
