For basketball, what you need is lean and agile muscle. Don't expect to get "bigger" training lean muscle. If you look at pro basketball players, they all look pretty slender and you won't find big arms or legs. What you will find is hard arms and legs. There is no "fast" solution for that

With that said, you will want to limit your weight training and concentrate more on aerobic exercise that works your agility (nothing beats working on the typical basketball training exercises). More than anything you will want the endurance that comes with aerobic exercise. When it comes to diet, eat a normal healthy diet and keep the fat and sugar to a moderate normal level (these won't help you much). When your appetite goes up, supplement the extra hunger with vegetables and protein. You can down a protein shake a little while after your personal training when the hunger hits you, but try to keep most of your protein intake to beans (also includes peas and tofu... don't be knocking tofu), grain, and lean meat.

This probably is not going to get you the kind of visual results you are hoping for, but you will be well ahead of where you would be if you packed on bulk muscle.

Cardiovascular conditioning, and stretching, will work a lot better than building up those bulky oxygen using muscles.

Low on the fat, and high in the veggies, grains, and one baked potato per day. Before any work out, stretch as a warm up will prevent many injuries, and keep the circulation going.

There are many aerobic exercise for the wrists, ankles, knees, and torso, but the main thing is know when to quit, and how to rest, as important as the exercise.
