Really?? You must be all white fiber LOLOL… I find the wieghts do me in… It rained yesterday so I went a little harder on the squats b/c I did not run. I felt a little stiff this morning but boy did I feel like I could barely jog tonight. After I got to the end of the big tempo session I felt real good… It could have been the theivery corporation pumping in my mp3 player too
