I agree with Sparky guy on this one. I very rarely use the one knee drills becasue I believe that the leg and arms must work together when pitching. With that being said I will use it from time to time when I have a beginner pitcher (8 and 9 yr olds) and they struggle with the arm circle. After they have the basic arm circle I do not use the one knee drills anymore.
My daughter is 14 yrs old been pitching for 6 yrs and we have never used the one knee drills. Again only use with struggling beginners.
