In this video, Myles talks about one of his favorite drills that focuses primarily on accuracy and consistency. It requires mastery of all fundamentals to be done correctly. The drill requires you to complete 3 rows of increasingly large circles, however, the amount of shots in each circle increases with each row. You start by placing one shot in each small circle in the top row, working left to right, then down to the middle row with two shots in each circle, and finish with the last row with three shots in each circle.
