This question is completely dependent on age. If you are in the youth age group (younger than 5th grade), I’d recommend playing as much as the young athlete wants. Teaching basic fundamentals and just allowing them to have fun. This is also a good age to allow them to play as many sports as possible so they can improve their motor skills. Supreme motor skills at a young age will equal high reward for the young athlete at an early age.
If you are in the middle school to high school range and you are serious about basketball, you should find yourself a basketball trainer in your area and create a workout plan with them and your local coaches (school coach and AAU coach can help in development plan). I would say between strength and conditioning, basketball workouts, and film study, you should spend at least 10-15 hours a week on basketball minimum if your goal is to play college basketball. Now only 15 hours of basketball workouts or only 15 hours of film study won’t work, so you must have an organized plan and be purposefully looking to improve key skills for your position to become a college player as well. This question is very specific to each person. For more details feel free to contact us to talk about basketball workout plans with you.
