I've pulled a calf muscle, hamstring and injured my wrist working out before. Too much weight after I hit a plateau. My trainer was pushing me.. hard. And finally one day my wrist snapped while doing forcep curls and it didn't heal for a few weeks. Its still not quite right. But I've learned my lesson after that. Now those days that I feel like pushing myself, I take a breath and say, save it for another day. I'm still trying to get back to my "former self". Matter of fact, pics from that day I showed at the Southern Import Showdown with my car and the ones from HIN show a difference. It's been a few months since I've started working out again, but it's been worth it. Not really on a routine at this point, but I try to do legs and lower extremeties two days a week, and arms, chest and shoulders on another day. Some days I do everything at once, but with lower reps so I don't burn out. Matter of fact, I'm going to get my clothes from my car and work out here in a few before I decide to just go home, jump on the couch and play my PS2. lol
