No Energy, No Excuses — You Can Do These On-the-Mat Ab Circuits Without Even Standing Up

There's so much to love about ab workouts, and I'm not just talking about how they strengthen your core muscles and give you that hurts-so-good burn in your midsection. Beyond all that, one great thing about a lot of ab workouts is that you can do them without getting off your mat even once. Yep, today we're talking about ab circuits you can do while lying down, which are great for when you're dealing with injuries, need a no-noise or small-space workout (#ApartmentLiving), or just do not feel like being on your feet right now. Been there! Am there currently!

These seven low-impact, no-standing ab workouts can be done anywhere and any time; just make sure you have a mat or a comfy floor you can do them on. Fire up your favorite one to get your core going ASAP. And, don't worry — just because you're not on your feet doesn't mean you won't be feeling these workouts the next day. We warned you . . .
