COVID was a big hit my my health as well - wife refused to let me go back to the gym, and my maximal lifts plummeted to beginner levels, but I was able to slowly get back up to a somewhat respectable level.
...and then we had the coming of our second child, followed by not one - not two - but three respiratory illnesses brought back from my toddler's germ factory - err, i mean 'daycare.'
Another issue that came with COVID was treating the making and (especially) consumption of fermented beverages as a part of my daily routine, instead of being a treat or reward for a week's hard work.
But hopefully, fingers crossed, as soon as my current respiratory infection goes away, i'll manage to start fitting in the gym on my lunch breaks --- unless the kid brings home another weird disease again
one important thing to note is not to jump in too hard, too fast - when i restarted after gyms opened back up, I pushed myself too hard and ended up hurting myself badly, and having to sit back out of the gym for nearly a month again
