I am more than half way through MMA fighter Georges St. Pierre’s 8 week Rushfit program. I love it, especially how quickly I see gains in strength without injuries or soreness. (I should add that I am only doing the workout portion and never even read all the way through the nutrition aspect of it.)
Kickboxing is probably my absolute favorite workout. If you enjoy a tough workout without too much instructor-perkiness, it might be for you, too. This review covers three different kickboxing instructors that I most certainly recommend, all of whom are available for checkout at the Library.
