Are you ready to shed your heavy sweaters and snow boots in exchange for tank tops and sandals? You're not alone! While bone-chilling temperatures may not be entirely behind you, spring will be here before you know it—and bikini season soon after that. No need to panic! If you start shedding your winter layers now, you'll be looking and feeling great with plenty of time to spare.
This abs workout is the perfect way to give your core a serious wake-up call and bring your flat, sexy stomach out of hibernation. By starting with a standard plank and then moving into plank variations, you'll tighten up your deepest abdominal muscles, as well as your glutes and legs, in record time.
Workout details: Three or four times a week, perform 3 sets of each exercise in the circuit.
