I have been reading this thread a bit and several of you guys are pretty serious about your work outs. I don't have time for 2 a days but I like to embrace the burn everyday on my lunch hour. I have changed my training in the last year as I was struggling with being injured from too much running and a weak core. I added TRX training 2-3 times a week and I have been pretty much injury free for the last year. I'm heavier now but I'm Running the longer races just as fast and not much slower in the 5k's.
Not sure if anyone else has mentioned doing TRX in this thread but I'm sold on it. I had all but quit wight training as it was killing my low back and aggravating a torn labrum in my shoulder. I feel like I get most of the benefit of weight lifting with causing aggravation to 45 years of abuse.
