How many hours do professional nba players work?

I heard that the average nba player make over 5 million? But do they train vigorously every day. I hate to become a b bal player if they are training like 10 hrs a day?|||depends on the basketball player and teams workout regimen.some players in their spare time workout an hour a day,others 2 hours.they have practice on off days for like 2-3 hours.but when you look at it,they are making all that money and only work 2-3 hours a day......and it improves their physical fitness.they stay healthy and work at the same time.i work 12hrs a day/6 days a week as an engineer and can only dream of the money they earn.but i do great to the average person though,lol
