Hi! I fell off the diet & exercise bandwagon about 2 years ago, and I gained back 30 of the 50+ lbs. I'd lost. In the past couple of months, though, I've found my enthusiasm again. I'm counting calories and have lost about 9 lbs. so far. I haven't been exercising, though. I want to get back into it, but this time, I'm in the mood for something "low tech," so to speak. I was wondering if anyone here has done resistance training using only bodyweight exercises (e.g., push-ups, pull-ups, etc.). If so, what were your results?
