2. Step-Up: Three sets of 20 reps, 60 secs rest in between

3. Burpee: Three  sets of 20 reps, 60 sec rest in

If you're not feeling sit ups, this is the best workout to rock your core without a crunch in site.

A circuit with all floor moves. If you don't want to get up, you can convince yourself this floor workout is just an extension of your bed and you'll be

closer to a 6-pack before you know it.

1. Bicycle Crunch: Three sets, 20 reps, 30 secs rest in between

2. Reverse Crunch: Three sets, 20 reps, 30 secs rest in

between

3. Plank: Three sets, 60 sec hold, 30 sec rest in between

Lastly, do a bonus plank and hold it as long as you can. Try to do it a

little longer each time you revisit the workout.

When you want your heart rate up and your abs burning, be sure to keep your core strong throughout these standing moves. On the plus side, there's nothing involving a

plank, burpee, or crunches!

1. Jumping Oblique Twists: Three sets of 30 reps (with a left and right twist jump counting as one rep), 30-60 secs rest in between

2. Standing Side Bends With

Weights Overhead: Three sets of 20 reps (a bend to the left and right counting as one rep), 30-60 sec rest in between, if you don't have weights, bodyweight is fine, just slow

down your reps.

3. High-Knees: Three set reps, 60 secs each, 30-secs rest in between

Take your pick of any of these circuits and your gut'll be gone in no time. And if

you want to roll right back to bed after killing your core, we won't judge.
