Ok first off I dont know a whole lot about working out/lifting etc. I have been working out for about 3 weeks now. I am about 6' and 225 lbs. All I want to do is really lose some fat and gain some muscle in the process. I don't care about weight really, If i gain weight from gaining muscle oh well, as long as I loose fat. Currently I do about 45 mins. on the bike everyday (burn about 350 cals) and lift weights for about 20-40 mins after the bikes. Currently I do tri's and chest and the next day do bi's and back. I just alternate those. Also in addition to those I do some other random things.... all legs, abs, shoulders, etc. Those are just randomly mixed in to take a break between sets and stuff. Now on to my question, Should I take protein and creatinine to help out with gaining muscle or do I not really lift enough to need them? A buddy of mine said to go ahead with the protein, but hold off on the creatinine till I start lifting for longer periods of time (like if im not hitting the weights for more than and hour at a time my body would just store it and not really use it). So sorry for the newb questions, but what should I do?? Also Im eating about 1500-2000 cals a day. I know it should be less but for now thats what im doing.
