Alright, so I am a 15 year old that is in off season AND powerlifting, i cannot get out of either of these, so i have to deal with 2 workouts a day, is this ok to do? or should i take something to allow my muscles to heal faster?
First, if you're OUT of season, then you DON'T need to do THAT much training (you don't want to burn out or overtrain to the point where you CAN'T train; that wouldn't be conducive to anything). And if you are, then I seriously hope that you're eating enough to feed an ARMY!!!
Second, if you're training like that, then you're NOT giving your body time to RECOVER (which is when you will make your GAINS!)
Third, as I said, muscles "heal"/adapt in your RECOVERY time (Faigenbaum & McInnis, 2003). If you're dead set on following such a training regime, then some of those sessions will HAVE to be lighter (or as the body dictates).
