It doesn't matter what time of year it is—your abs can never be too defined. And this high-intensity circuit, which focuses exclusively on your midsection, will go a long way in keeping your core in check.

Incinerate flab and carve your core with back-to-back rounds of elbow-to-hands planks, reverse crunches, crunches, hollow holds, and alternating shoulder taps for a muscle burn you probably haven't experienced in a long time.

Directions

You'll do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 to 60 seconds. Repeat the entire circuit for four to six rounds.

Depending upon your ability, you may shorten or lengthen the rest periods between circuits. You may also complete more or fewer rounds.
