Studio Lotus, with two locations in Atlanta and Marietta, is offering a coupon for $159 worth of classes for just $59! The classes include pilates, private sessions and Kettlebell classes. I had never heard of Kettlebell classes, but apparently they’re pretty awesome and can make you burn 20.2 calories per minute! Kettlebells are “magic little weights” and the classes include an introduction into how they work and integration of the weights into core-strengthening pilates. Check out this Groupon with it’s full explanation, but act fast! This coupon is only available today, but is redeemable until August 26th, 2010.
