Now I am older, married, and don't see much point in wasting time building muscle anymore. So I bought a treadmill for my own home. I use it ever 2-3 days for only 20-30 minute and I hate it. It's painful, it's unbelievably boring, after using it I'm exhausted and have to take a shower. I cannot listen to podcasts or watch TV shows to fight the boredom because the experience is too intense to fully focus on something else. I cannot even really think about things.
When I got the usual vaccine side effects the other day, I thought "at least I have an excuse not to exercise".
I know exercise is important, but I wish it wouldn't be so terrible.
