I feel like there is no rhyme or reason to what we use and what we don't.
I never liked the stationary bike and I really like the gym, so I was shocked to discover that I'm the one who uses the peloton most frequently, almost daily. I love hand weights at the gym but I rarely use ours at home, although hopefully that will change when we get our little rack set up. I use the Pilates circle a lot, and DH uses those band things daily. The treadmill doesn't used a lot, but probably enough to justify buying it. DH is the only one who uses it and uses it only a couple of times a month, but he also doesn't have a gym membership that is going to waste.
I keep my gym membership because I like a few machines there, the elliptical, and for some reason I do my free weight exercises there more regularly than I do at home. But it's 40 dollars a month so I don't feel like it's a waste to have that and equipment at home.
