Re: Johnny Groove 1-6, 4-6 vs. Marc Yurgenson (ITF #2,223)
Do you do accuracy trainings on the wall like standing in a particular position and hitting 5-15 shots in the same place (middle or down the line?) I reckon they are the best kind of exercise you can do to improve the accuracy of your shots if you dont have a hitting partner. Just dont overhit.
