How can I make a good training plan

I have never made a plan before and I'm hoping making a plan can make me a better player. How do I start? Thanks for the help.

Alimn: You question is very broad, fitrst of all, I need to know your age, your experience, where you are from, what level of basketball you have played, what previous training your have had, what are you accomplished at what do you need to work on. Until then, this is a mute question ....Coach Mac
