I can seriously relate to this. I have been going to the gym 5-6 days a week for years and absolutely loved it. As soon as the gyms closed down, my motivation to stay in shape plummeted. It was like a light switched off. I did absolutely nothing fitness related for a few months, just waiting for the gyms to open back up.

I finally started biking recently, but I struggle to get motivated and get out of the apartment to do it. That was never a problem when going to the gym.
