For you, summer (not to mention spring break) has always meant freaking out in a dressing room while trying on bikinis and hiding every ounce of your body underneath a designer tunic.

Might be time for a change. This year try one of these new classes and get yourself bikini ready for summer:

Kranking: Like Spinning but for the upper body, Johnny G's latest shape-shifting sensation uses a cycle (see photo) for the arms to sculpt shoulders, build biceps, and burn fat fast.
Try it out at: Equinox, various locations or at Club One.

bodyBrasil: Get the physique of a certain leggy Brazilian bombshell with this total-body toning class, which fuses capoeira-inspired core-strengthening drills with weighted resistance.
Try it out at: Sports Club/LA at Rockefeller Center or at Zone Hampton.

Mind-Body Blend: Find (and tone) your center with an invigorating fusion of yoga, weight training, and meditation that will strengthen and loosen even the most tightly wound body.
Try it out at: Clay, NYC.

It's all worth it in the end.

Because this summer, you'll be able to grin and bare it!
