I cant begin to tell you how big the resale market is for unused home gym equipment.
Not for the high end of the market.
I think a lot of the “big market” for used home fitness is low quality stuff advertised on TV or sold at WalMart. People don’t end up using it because it is uncomfortable, wobbly, and hard on the joints.
I am tightwad, so I looked used before buying my $9200 elliptical (now $10,200). I really wish I could have gone with a cheaper model too, but I was used to a particular model that I used for years at 24 Hour Fitness and EOS, and everything else felt flimsy, shaky, and unable to let me go all out when doing interval training.

A lot of equipment hit the market at that time because of gym bankruptcies. It got snapped up in days, I know because I called the listings for multiple gym bankruptcy sales.
