We (Sandi and I) tried a muscle up class today. It was good in the most painful way possible! It's similar to a 'Body Pump' class at Good Life... lots of weight lifting and bench presses, squats and lunges. My arms are throbbing. It hurts... it hurt during the class and I am sure it is going to hurt tomorrow. I did this class in lieu of Boot Camp on Friday. There is NO way I risking the muscle pain for the trip... its suppose to rain the first 3 days... I can't handle that and leg cramps.
