One last thing for all the P90Xers etc. Look at HIIT training from 15 + years back and it will look very familiar. I am glad these new catchy training programs are getting attention and helping people get into shape but it is not new. I am open to any of the more experienced back pack hunters who can help me design my training to be less body builder and more conditioning and useful strength. I freely admit I was trained in that size matters and that was the end goal. Now I want to be healthy and conditioned and able to handle the rigors of a 2 week backpack hunt with just the gear in my pack.
