I have a home gym (kind of like a Bowflex) that you can work each body part, and some free weights as well. Also a stationery bike (& a real bike) & a pool. A yoga mat, some resistance bands and a stability ball. And I live in a great area near walking/hiking trails & the beach.
Out of all these things, it's the resistance bands & stability ball that I rarely touch. All else gets used.
My husband & I used to be members at the YMCA. After 3 years, I finally figured out that we could have had a home gym paid in full by now! - and I really HATED waiting for a specific machine and all the "everybody's sweat" stinky-yuck & so forth. Plus, even tho the Y was very close to my home, it is just SO EASY to roll outta bed & into the next room, as opposed to getting dressed, driving to the gym, etc.
I used to have a treadmill, but traded it for the stationery bike when my knees started hurting so bad. I use the stationery bike more during bad weather or when it's too hot or too cold to walk/bike outside. I much prefer being outside to inside. Walking the trails or on the beach is one of my favorite "movement" activities.
The weights are easy - that's an indoor activity. But I love to swim, and during the spring/summer/fall I get in as much swim time as I possibly can. I always feel so relaxed after a good swim. And of course, during the heat of summer, a good swim is just incomparable to any other exercise - cooling & refreshing & you don't notice the sweat cause you're already wet.
