Not sure why creatine is getting such a bad rap with a lot of you guys. Sure we all read the research suggesting its efficacy with short duration energy expenditure and not so with extended muscle contractions. So we know that most weight lifters have sufficient rest periods for it to work like it should. If youre running for long periods or even doing back to back exercises like in crossfit or circuit training it may not be effective. That said creatine is a huge deal. Also, I hate when people make statements of the sort saying that it only adds water weight. Your body is made primarily of water anyways so this argument is self defeating. Creatine is awesome, period. Get yer a s s e s some creatrona and we'll make you a believer!
