If you gain a pound a year, it adds up. In 30 years, that's 30 pounds heavier o_O In this past year, I've gained about 6 pounds. The goal was to gain 10 pounds, but I'm quite satisfied with where I am :]. It was the first year [by year, I meant summer] I went on a high protein diet and worked out seriously too.
I'm the same weight. Maybe a pound or two less but last year I was working out 20+ hours a week. This year? Not so much. I'm pretty out of shape (atleast comparatively :( ) so my body fat percentage has likely definitely increased. I'm working on it though.
