Flat abs in four weeks

Whittle your waist with this 20-minute routine based on Kira Stokes’s super-hot Core Cuts class at the Reebok Sports Club/NY. These standing ab moves require lots of balance and stability, giving your core muscles an extra challenge.

Do this workout 3 times a week (plus 40 minutes of intense cardio 4 times a week)—and you can lose 2 inches off your midsection in just four weeks. Do all the moves once, then repeat the entire circuit 2 more times.
