Because you want to play basketball, you should keep good physical coordination and flexibility. Muscles are not suitable for big! Shoot and dribble, so let your deltoid muscle stand out, but also pay attention to practicing your explosive force and ligaments, and do aerobic exercise every day, such as cycling and running.
To put it simply, two months of persistent practice can produce muscle effect, and daily 1 hour of substantive training is enough.
Personally, I suggest you practice your legs more, which is very helpful, hehe!
