As a Gym, I like the YMCA. It's less crowded that all the commercial gyms.
They need help maintaining their stuff. It can take months, years, or never to fix things.
The model C rower at the gym had been down for a while, it would not turn on when you pulled the bar. Which is a shame, as someone had put a more modern PM5 computer on it. With the concept 2 app on your phone, you can link it to the PM5 via bluetooth so you can record your rows or even get into on-line competitions etc etc.
No-one was fixing it, so I thought I would have a go. And it worked.
Investment ~$30 for the part & my labor (free)
