In the Victorian era, people made their cores look tight by wearing corsets, which doubled as bulletproof vests during pistol duels. Strengthen your core until it's naturally impervious to bullets instead with today's Groupon: for $49, you get five specialized fitness classes (a $155 value) at RockIt Body Pilates, which has two locations—Manhattan Beach and Redondo Beach. To ensure the best results, all five classes must be used within one month of the first session.

RockIt Body's workout combines Pilates, cardio, and strength training to achieve quick, visible results. The low-impact, high-energy classes burn fat and tone muscle without bulking up like a professional baseball player or punishing the joints like jumping into the unfilled swimming pool that sits at the base of the Eiffel Tower. Classes include programs such as RockIt Body Pilates, which incorporates cardio work, strength training, and energetic music into the core Pilates posture work, and RockIt Barre, which fuses dance, cardio, barre work, and light resistance into a seamless sculpting program.

RockIt's dedicated staff works hard to keep the challenging classes fun, positive, and highly addictive, handing out helpful advice, reinforcement, and cans of Flurme. Owner and founder Judie Aronson, an actor who has to stay fit for roles, started RockIt Body Pilates to help people stay fresh with their workout routines.

Reviews

Yelpers give RockIt Body Pilates a 4.5-star average rating:

• Classes are fun, challenging and it doesn't take long to start seeing results. – Rebecca V.
• I sweat from beginning to end and drink an entire big bottle of water before the 50 minute class is over. Surprisingly, it works your entire body: legs, abs, arms, back, shoulders and I usually can't move the next day. – Alexandra E.
