I've been using the free tier for a few years. I want very little out of it -- really just something to say "do these exercises today".

The basics work well enough. I'd just as soon they didn't lock alternative exercises behind the paywall -- if my gym doesn't have a leg extension machine, what's a good alternative? It doesn't seem a lot to ask.

I'm well aware that I get what I pay for on the free tier. But I worked around it by googling an alternative and just substituting that instead. It's good enough for my extremely meager purposes.
