It always gets on my nerves when people talk about which diet they should get on, or what gym they need to join to get fit.
I'm 6'0 120 lbs, and I've never really worked out much in my life. You want to know how to stay fit? WALK AROUND. It does wonders. my first week at my university I lost almost 10 lbs simply because I walked so much.
You can eat anything you want, I do, I bet I eat around 4-6k calories a day.
As for gaining muscle, I don't really know much about that haha.
Maybe I should make some guide that would help me get rich quick that says nothing but "WALK"
