Just one quick thing to add.
People buy nice exercise equipment then get old, fat, lazy etc and don’t use it.
There is a ton of it you can pick up off of Offer Up or Nextdoor for cheap or free.
I got a pretty nice threadmill for free.
It sucks compared to walking outside, but when the weather is [Bleeeeep!] it works well. Throwing some good tunes on makes the 45 minute to and hour walk on the thing go by pretty quickly.
