Deck 3— PHASE 2, Lower Body Workout: link

Bonus Workout
We have one poolee who is trying to drop extra weight in order to ship next week. That means he has to burn a lot more calories than he takes in. We shuffled the phase 2 upper body and lower body workouts together and did them as one giant deck. It takes about an hour to do, but it really wasn't a bad workout. The upper body and lower body cards don't stack close enough together to reach failure. Afterward, we went on a 4.5 mile hike and finished up with a game of football. Heck, I dropped a few pounds yesterday and I wasn't even trying (at least in terms of diet).

Walking is one of the best kept secrets at Marine Corps boot camp. Recruits walk just about everywhere they go. The push ups get all the attention, but if I had to guess, I would say that most of the weight loss recruits experience comes from the massive amount of walking/marching they do. Their bodies are almost constantly in motion.

My good friend and fitness guru, Tony, is an advocate of walking as a weight loss method. He wrote a column for OO-RAH.com about it a few years back. The information is still good, though, so here is a link from the archives: Link
