Whats the best way to improve my tennis skills?
You need coaching. Playing vs better players helps a little, but even 2 or 3 lessons will shave a year off your learning curve. Most health clubs (if they have tennis facilities) have a pro that can give you lessons. They’re usually pretty reasonable, and it will immediately improve your game. Tennis is ALL about technique. If you learn a bad technique, you have to unlearn it, and it takes years. If you don’t know you’re doing something wrong and you continue to play, you develop bad habits that weaken your game and your ability to learn the game. Take some lessons NOW. They will help you for the rest of your tennis playing life whether you play competitively or not. Have fun and good luck!
