Partner basketball shooting drills are great for getting up a lot of a certain type of shot in a short time. Along with shooting you can also work on practicing passing with your weak hand as well. It is important that you shoot at game speed during this basketball drill and treat every shot the same way. Really work on building your muscle memory and shooting with the correct technique.
There is no point in practicing your shot in a different way than you would shoot in a game. Make sure that you are down ready before every shot, and that you are getting your work done prior to receiving the pass.
