Yep.

Quit going to the gym thanks to covid and just started back up a couple months ago. I thought I felt fine before. After a month at the gym just doing super-basic, non-stressful cardio to just improve overall health and I realized that nope, I was not fine. Way better now even after just a month with 4 days a week at the gym and low-impact exercise.

Getting off your ass is highly valuable.
