I'm 29 and I'm about a 4.0. I want to start playing league tennis next year and want to be good enough to be a solid competitor. Lately, my forehand's been quite the issue. I'm not sure if I'm thinking about it too much or a combination of things, but it hasn't been as solid and consistent as it was about two seasons ago. I've never taken a tennis lesson in my life, so I was wondering that maybe taking one or two private lessons could help "re-adjust" somethings I'm unconsciously doing wrong. Have any of you taken some lessons to improve your stokes? Is it worth it? I was thinking of just saving up for a tennis ball machine, but a ball machine won't tell me what I'm doing wrong. But then again, the repetition of balls could help me. Any advice or thoughts would be appreciated.
