Basketball is a great sport, and it is very easy to practice on your own. Here are some tips on how to get better on your own time.
The best thing you can do to practice basketball on your own is have a basketball in your hands as often as possible. The more accustomed you are to the feel of the basketball the more likely you are to succeed.
If you want to work on your shooting go to the nearest hoop and start out in close and work your way out. Make yourself make layups, then short jumpers, free throws, and then work out to three point line. Additionally, you can work on your shot even without a hoop just by constantly practicing the proper motion and follow through with your shooting hand.
If you want to practice your defense simply go outside and get in your defensive stance (knees bent) and practice some step slides. Don't just go through the motions, but rather try your hardest and act as if it is a real game.
Basketball is a game of quickness and stamina, so working on these things is very important. Running often and doing things such as jumping rope often will help improve your footwork.
Basketball is also a game of strength. Work on lifting some weights for your upper body as well as your lower body.
Most of all, dedicate yourself to the game. If you put in the time, the results will be there. It isn't a quick process, but it is a very rewarding one!
