Never been to a gym. And at 68, and healthy, don't feel the need. Of course, some of this might be due to having an old style SoloFlex (the one with the stretchy rubber things), and a gym quality treadmill at home! Don't think that taking care of mucking a stall, cleaning up horse manure, keeping the hay stacked and putting it in our storage area (hay bales aren't light) & carrying 4 gallons of water to fill up water buckets is hurting anything Just wish the horse could "hold it" in wet and cold weather!! He's a gentle, big pet, so can't complain, and it forces me to get some exercise every day. (guess I could complain, but he'd just ignore it anyway!)
