I mentioned kettlebells above. I've used 'em for years - they sure helped me get my belt size smaller after I quit smoking. But not everybody has used 'em - they didn't have 'em available when I was falling down a lot (can't really cut it) gymnastics crew in High School. But I hope they do now. kB swings work a heckuva lot of muscles, easily, safely and in not much space. Turkish get ups? They're simple and danged effective.

I always claimed I couldn't afford to join a gym - so I bought Kettlebells, dumb bells. that mace and my garage sale 'indian clubs'. The key is - use 'em on a pretty regular basis. In hot weather, I tend not to. But that excuse is fixin' to come to an end. I've been doing the indian clubs and some dumb bell work for a few weeks now. Down 95 lbs and trying to lose 5 more so I can be insufferable. "I lost 100 lbs, and in my opinion you should (do whatever I suggest)"
