5' 8" when I was in my 20s I THOUGHT I could not get over 160 lbs MAX. I worked out 5-6 days a week 1 1/2 - 2 hrs a day and ate what I though was a lot only thing is knowing what I know now it was mostly empty calories.
If I had eaten chicken, tuna, fish, veg and other food like I should I could have easily gotten up to 180 in no time.
I was also over training and not training right. My form was not bad but I just didnt now enough.
I would have sworn or bet 1mil dollars my diet was great and I was doing everything correctly.
#1 is diet for loosing fat and gaining lean muscle.
