Continue your regular workout program and hope that Dodgeball comes up. If it doesn’t, either look for it again in your next session or choose to do extra drills. It usually shows up at least once if you re-do drills.
At the start you’ll want to stand at the starting point. Once you’re set and the drill starts move completely out of view, just enough so that your image outline is no longer visible. Dodgeballs will keep flying at the wall but there will be no one to hit. You know it’s working because the instructor compliments you on avoiding ten in a row and other comments of that nature. Should unlock shortly after the completion of the drill. This particular method will not
work for Split Decision; the glass will break if you try to use this method.
This works in a similar fashion for the Artful Dodger achievement (solution here
), but with a bit of a tweaking. Since you have to do that one through the Challenges menu though they both can’t be done together.
