I try to walk a couple miles per day on Sweatcoin.
Haven't tried to jog for years because my calves are huge, after a while the blood in them pools up, and I had a couple occasions in relatively rapid succession where I had a sheet of muscle separate from top to bottom and across in my calf and I had to hobble my way back home - couldn't walk normally for a couple weeks.
Moral of the story - know your body type and know your risk signals.
