In this video, Myles talks about a drill to work shot cadence, accuracy and other fundamentals. Instead of moving horizontally, this drill requires you to move vertically, starting from the large, bottom left circle. Place three shots in that circle, move up to the medium, middle circle and place two shots, and then place one shot in the smallest circle at the top. Then, move back to the bottom row and repeat.
