So let's break this down. Every week there's a fast ab workout that you'll do for four days of the week, plus a HIIT day, a sprint day, and a rest day. And each week this month, the ab workout gets a little bit harder (and a minute longer) so that by the end of our 30 days, you're ready for our 9-minute ultimate ab assault superset. (Sound crazy? We promise if you stick with us, we'll get you there!)
