If you were able to take all 30 swings without flooring yourself (remember what that means), I want you to try again. Literally go back to the last slide and try again.
If you floored yourself at least once, your next task is to do it again, but now you only get 15 hits to do it in. Again, if you fail with 15 hits, floor yourself anyway. Then try again.
Is it getting harder and harder to get back up?
Good.
