Back when I was 24, I trained BJJ about 3 or 4 times a week and jogged on my days off. I was slim as fuck. Now I'm 30 and my whole god damned body is breaking down. My lower back always hurts just bending over, my legs are weak as fuck, and my joints pop just getting out of bed. I've got tiny as legs and a long torso, so it makes things a little difficult. I'm trying to get back to form and make moving a little bit easier. What do you guys recommend?
