Joe Marsh is doing a great job in explaining all of the movments and keeping us from injuring ourselves. I'm in the on ramp course which is an intro to cross fit and helps establish proper form for the movements. The end of each day is a highly intense workout which always kicks my butt, but its totally worth the whooping to feel stronger! I highly recommend at least the on ramp (that's all I have experience with) for anyone who either has or will have fitness and strength training as a part of their life!
