I can attest to that. haha. Actually He is a diamond in the rough and could probably kick my ass.
I have been lifting for almost 20 years. Was always skinny trying to gain size and strength. A few years ago I weighed 275 with about 15% bodyfat and was strong like OX. However, haven't lifted as hard since then and am in the same boat as you. Trying to tone it up a bit and maintain some muscle mass. If you do cardio 3x /week for 1/2 hour and lift wieghts 3x/ week fopr 30-45 minutes (not talkig to your buddies but actually lifting) you'll be fairly fit. You may not win and bodybuilding contests but that is not your goal. ALso diet is a huge part of it. Cut out soda pop and fast food and you'll probably lose 10+ pounds right there. Good luck.
