How many hits could you take?
1-5 – That. Was. Pathetic. I want 20 hits at [4]. I don’t care how long it takes.
6-10 – Almost there. However many you managed, do that 2 more times. So if you did 8 hits the first time, I want 16 more. At [4] of course.
11-15 – Good, you’ve got the intensity just about right. Take a breather, then give me 10 more hits at [4] before you move on.
16 or more – You are not hitting yourself hard enough. Try the task again, but this time try to really bludgeon the absolute fuck out of those balls. Think about how hard I would hit them.
