Perhaps I’m reaching, but why not just run outside? Cold? What’s a gym cost where you are? $40 just seems like a lot in addition to the amortized cost of the basement clothes rack, I meant exercise machine.
I run daily and live in a climate that gets unpleasant or impassable to run outside for a good portion of the year. I also live about 20 minutes from the nearest gym so there’s also the time savings which is the primary reason for the home gym.
