So...have you heard of Les Mills? They are this awesome company based out of awesome New Zealand and they create the best most challening group fitness classes! I discovered Les Mills classes when I was working at my sedentary desk job right out of college, and they kept me from going stir-crazy in that period of my life. Fast forward almost 3 years later and I am still a Body Step addict and also I became an Instructor myself!!
