Let me describe my body type first. Im 5'10'' and weigh 180 being pretty lean. I am 21 years old. For the longest time i was stuck at 70lbs in each hand doing incline dumbell presses. I finally decided to take some creatine after a long layoff from it. Well i got up to 80lbs in each hand for 6 reps and today, i finally got that 7th rep. My reps are full reps, from lockout, all the way down...no half reps. Is this good for being 21 (natural) or should i be at about 100 lbs in each hand by now?
