i just read the above sticky about beginners and weight training and there was a good bit of information. i was just wondering if someone could clear some things up. one of the things that stuck out was it specifically said don't train more than three days a week so you can have optimal muscle growth when training for size (which is what i'm training for). does this mean don't train more than three days a week if you're only on a full-body schedule? and there was also something in there about changing up the routine from time to time. if this is the case would it be okay for me to switch monthly from having upper body and lower body days 4x a week for a month and then the following month only do three days a week full body? also i've been lifting for about a month and each week i consistently gain about a pound so i assume i'm doing something right. also if it's worth mentioning i'm using two supplements: whey protein and serious mass, which are both ON products. thanks guys.
