I have been playing tennis for over 15 years. I did not play consistently all those years but have been playing quite a bit during the last few years. I play with different level players from 3.0 to 4.0. I participated in doubles clinics last winter. I also played USTA mixed last winter. I have two teenage children that have taken lessons and academies in the past. I have been exposed to formal training ( watching their lessons and drilling). I can't seem to break the 3.5 barrier. I could actually be a 4.0 when hitting but play like a 3.0 during matches. I believe my stroke production is okay. My footwork needs improvement. My goal for the following months is to improve this part of my game. It just gets frustrating when I double fault during matches and hit numerous unforced errors. I practice my serves....hitting 2-3 buckets several times a week. I don't think I hit many unforced errors during practice. I do well during practice....but fall apart during matches. I am not a pusher. I generate my own power but get beaten by pushers all the time. What can I do to move through this 3.5 wall? I do not have access to a video camera right now so I can't post a video clip. Please help.
