I did a kettlebell mile: Tried it with 20 kilo. It was quite hard, particularly on the grip.
I think next time I will try to go very very fast wit 16 kilo. And I will try to not switch hands so often.
I like to change the kettlebell mile with 16, 20 and 24 kilo.
No people are watching me, they are not busy being in their own minds, or even better their mobiles. Note to myself: Don't be like that.
