Maybe not radical, but I'm have a really good experience with https://www.future.fit/

They pair you with a personal trainer who comes up with a detailed workout plan just for you. Each workout arrives as a set of videos, showing ever exercise or stretch stitched together. You just follow along the video, but it's based exactly on what you want to achieve. (E.g. 'lessening pain from sitting and getting active'.)They send you an apple watch to track heart rate and ensure you're active.

B/c you text with your coach, and they see you're activity, you have a ton of accountability. So I've been working out more than ever while locked at home :)

Yes, it's a little expensive. But far cheaper than in person personal training. I'm benefiting from it!
