My home is not big enough for much indoor exercise, especially with my existing conditions. And we may as well be talking about a permanent situation for someone as I'll as me! Anyone expecting this lockdown to be lifted in two more weeks will be disappointed, I bet.
I'm sure there are some exercises you can do. I live in a small flat and can manage basic things.
So please stop trying to deny me the simple pleasure of a couple of hours on the bike a couple of times a week just riding towards the very flat horizon and back. I do not understand this killjoy mania. I will not harm anyone unless you are in the habit of licking country roads despite the cow exhaust.
Again, no one, and I mean no one, is trying to take exercise away from you.
