well, i'm still trying to figure out which one griffin's kettlebell classes are going to do to me.... but I can definitely say I feel the effects.  The workout seems so quick, fun and harmless - but don't be fooled, you'll get to know your muscles in a whole new way.  A GREAT new way!
Pros:  Great workout, Great Gym, Convenient Parking, Entertaining and Arse-Kicking!
Cons:  Temporary Soreness!
