OK, after having lost 14 lbs by modifying my eating habits, I decided to join my wife in working out. So I went to the gym Monday. I got TORN UP. I literally almost passed out (and I'm using the term literally correctly there). So yesterday I was pretty sore but what I consider normal from when I've started workout programs in the past. But today is a whole different level, I can't even straighten my left arm it hurts so bad. But today is gym day again but I'm going to have to take it very easily. Any advice?
