I walk my dog on paved trails about 3.5 miles a day. On weekends, I try to drive somewhere to dirt trails, or else try to go swimming at my mom's condo pool.
I just picked up some rollerblades at a garage sale, but haven't had the guts to try them yet! I also have cross-country skis for outdoor exercise in winter. I have a bike and a vision of myself using it to run errands, but I haven't gotten a lock for it yet. I also have a hula hoop in my garage that I am going to drag out, thanks to this thread.
I also do a lot of yard work with manual methods (walking mower instead of riding mower, hand tools instead of power tools), and I garden. [I wouldn't count these as exercise, but steps to being less sedentary.]
