First, knock off 250-500 calories from your current daily intake. That should be good for the weight issue as long as you play basketball and get enough daily activity. For handles try getting used to pounding the ball hard. What position do you play? If you're a post or PF you don't need to worry about having Super Handles but for SF,SG, and PG you got to practice your normal moves but at a higher and more intense pace. Also training you CNS (Central Nervous System) to be able to handle 2 balls at one time. Whatever you can do with 2 balls will me simple with 1 right? So get used to doing 2 ball handling drills. Oh and eat healthy. No Mc'D's
