Hi, everyone seems to be covering the basics here so not much really to add. But if you want to do a little personal research here are some good places, www.specialtactics.com these guys are fitness gurus and the info can be applicable at any stage of development. Check back periodically as they have different articles and such. Also they talk of nutrition and various workout programs. Has many links too. Once you get in a good workout frame check out Pavel Tsestouline (spelling?) you’ll know the name when you see it. And also take a look at www.mattfurey.com You don’t even have to buy anything if you don’t want. Just subscribe to the free fitness report and you can learn a lot. He doesn’t sell out your email either so don’t worry bout that. Usually I get about 2 or 3 reports a week. Later I do plan to buy some of his stuff. I’ll post a thread on it when I see the results. The stuff I learned at these places I incorporated into my kungfu training and it has brought nice results. But don’t go overboard with some of the stuff from the special forces site untill you’re ready for it.
Just remember train smart and stay healthy. My sifu always says “no one knows your body like you do” so really it comes down to you to know your own limits. But work to stretch those limits a little a time.
Stay strong
