If you’re going to try Linux, there’s obviously a ton of great options but I can definitely recommend ZorinOS for anyone unfamiliar with Linux.
I replaced Windows on my Mom’s computer with Zorin and she absolutely loves it. Its UI is simple and clean and the OS just works.
For me personally; no excuses. I have nasty ADHD and am very dependent on habit. I have to make a conscious effort to establish any activity as a habit if I want any hope of following through. This forces me to have a ‘no excuses’ type relationship with things like running, my favourite workout activity, if I want to keep it up in the long run.
