Physical Fitness Training Routines II

Seeing that we're all on the physical fitness bandwagon and such, here's one routine I found on the internet. I don't recall the exact site but I believe it was www.crossfit.com. It's called "the Murph".
Murphy was the name of the US Navy officer and an avid triathalete who is attributed to be the developer/inventor of the routine. Sadly Murphy gave his life in the war on terrorism in Afghanistan a few years ago and his comrades posted the routine on the internet in his honor. This much I do remember reading on the website and in at least one physical fitness magazine. I'll have to pay better attention to my sources in the future.
The "Murph"
One mile run followed by 100 pull ups, then 200 push ups, then 300 squats. Wrap up with another one mile run. The pull ups, push ups, and squats can be partitioned in sets of 10 or 20 or whatever just so long as you do 100 pull ups, then 200 push ups, then 300 squats. No particular order or sets, just get them done. No time limit either and simply start and finish with a one mile run. No weights involved save our own body mass and no special equipment required save a good pair of well cushioned running shoes.
200 push ups and running a couple of miles are not a problem for me, however I have yet to attempt 100 pull ups or 300 squats. I used to pump out 200 plus basic push ups with one of the guys at work before I picked up taekwondo. We'd do a pyramid routine of starting with 20 the first set, then 19 the next set, then 18 the next set and on down. Now to get down to the hardware store for a couple of bags of sackrete and a couple of 4X4's to set up a pull up bar in my backyard. I've been wanting to do that for some time now. Enjoy!
