When I used to workout, I just took a protein shake or two but no other supplements and that was it. I also used to work out 4 or 5 days a week and was sooo tired and irritated. I hated working out and I saw very little results.

Now, I'm working out and I only work out for about an hour and maybe 10 minutes (tops) 4 days per week. I use proper form and go hard on each set. I used to do HST training and had good results but 3 days per week just seemed too little and I thought I ought to change the routine anyhow, at least for a little while. So now im on a 2 day split. I do upper body 2 of those days and lower body the other 2 days. I limit myself to around 15 sets of exercises on each of those days. The problem is that when I'm done with a workout, I really want to keep going and have alot of energy left! I KNOW I could knock out another bench press or squat. However, I keep reading from so many different sources that the worst mistake is "overtraining". But I have so much energy and really really want to workout!

I take a protein shake in the morning, multivatamin, BSN creatine (which is amazing) and glutamine, protein shake after workout, lots of meals throughout the day, and a protein shake at night. That's not what I used to do before so i'm assuming proper nutrition, rest and these supplements are really helping me recover very well. However, I want to gain mass faster than I have been and I think that if I workout more, I could do it. What do you think? Is it really taboo or do any of you workout more than this? Would I be making a mistake? Anyone ever have the same problem? thanks!
