I guess it's time to admit it. I collect home exercise equipment.
I arrived here less than 2 years ago with my rebounder (mini trampoline) and yoga mat. EDIT: I forgot! Also hula hoops and flags.
Since then, I've collected a treadmill, Gazelle, Leg Magic, BOSU, stepper, wobble board, hand weights, and a whole bag of resistance bands. And a couple of weird balls (I think one is for massage).
I buy these at the thrift store. Not only because it's cheaper, but because no other store in town sells this kind of thing. So if I see something that I might use, I buy it on the spot.
