I then made my kettlebell stochastic.
After I flip the day's coin, I roll a 2d6 and multiply it by 10. That's how many swings I do that day. On average, 70. Maximum: 120.
I could, if I wanted, attach this to the coin: heads multiply by 25, tails multiply by 10, etc. Doing this would increase the max to 300, and the average to 210.
