If you're looking for a sport that can be both fun and competitive, slow or more intense, tennis might be just the sport for you. Playing tennis is a great way to burn calories, build endurance, strengthen muscles, and improve hand-eye coordination, but more simply, it can be a way to make friends and have a wonderful time. The act of running and hitting the ball is also a great stress reliever, and if you happen to get particularly into the sport, tennis is also a wonderful sport to compete.
For beginning tennis players, equipment need not be an extensive investment. In fact, you can take a short trip to your local department store or sports store and get all that you need. First, you'll need to find a decently sized racket. When choosing a racket, there will be several different head sizes and weights. Sometimes, the rackets may only be divided into children and adult rackets. Once you find a good fit, you might also have some various color options and furthermore, some price differences. If you're just starting out, most any racket that fits you well will be fine.
Secondly, you're going to need a stash of balls, because without some good-quality balls, your tennis experience will not be good. If you found some balls buried in the corner of your garage or hiding in the back of the closet that you've not seen in a good while, it's probably a wise idea to get some new tennis balls. Flat tennis balls make it hard to serve or return any hits and this will frustrate you on the court. You can purchase balls in sets of three or in bags of eight or nine. From personal experience, there isn't much of a quality difference between tennis ball brands, so you can really choose brand, color, and price preferences.
Finally, you'll need a good pair of tennis shoes that offer support and comfort as you play. Don't attempt to play tennis in flip flops, crocs, or sneakers that are meant to be style-catchers only. You'll want to purchase something that could be used in a gym-type setting that provides good traction, breathable fabric, and durability.
All of this will get you started in the sport of tennis, and as you get better and like it more, you can purchase other equipment. Further tennis equipment can include ball caddies, wrist and hand bands, or special tennis attire and shoes, all of which can be found at local sports stores or online tennis shops.
