This exercise is simply toe touches with your opposite hand. To execute this exercise, all there is to do it is extend both arms fully along the frontal plane, than rotate and flex at the pelvic girdle to reach down and touch your opposite toe. The reason this exercise is helpful for bunting is because it can strengthen and quicken to hip flexors and hip rotators, and can strengthen the abdominal muscles. The hip rotators are the important part because when bunting in a game, you need to be able to rotate very quickly, and this could help with that.
