Let me tell you a little bit about the instructor for the Mon/Wed night Chisel class at my gym. First of all, he's a guy. Secondly, he used to be a marine. As you can imagine, he brings a strong military-style to his "butts-n-guts" workouts.
Last night was no exception. He thought is would be a great idea to start off the new year with 2012 crunches. for realz. holy crap! Here's the breakdown...750 regular, fast crunches. 100 oblique crunches on each side. 50 military-style full sit ups and then 12 crunches with weights under your chin. All of this interspersed with some serious leg & butt lifts.
Holy crap but I did this!!!! every single damn one of them. AND after an hour kickbox class. go me :)
