I agree. So much so that I built a website to support that same theory - that you are better off with your own equipment selection and an internet-connected screen.

The website, Slipstream https://slpstream.com is a human-curated (high quality only) aggregator/reviewer of the best content for treadmill/indoor bike workouts.

Inspiring documentaries, guided workouts (I've used the GCN ones for several years and love them), podcasts...

There's a filter so you can find what you need fast and if you register (free, username + password) you can bookmark your favorites and save them to a playlist.

My goal is to reduce the friction between wanting to workout and getting it done. To flip the switch from a chore to something you are excited to get to.

I'm trying to prove product market fit right now so would love any feedback :)
