What's the difference?
Hoop workouts are for athletes who have access to a basketball hoop. It doesn't have to be fancy or have a lot of space - room for three pointers is a bonus but not required. These workouts will include ballhandling and other skills as well as shooting.
Garage workouts are for athletes who don't have access to a basketball hoop. These workouts will focus on ballhandling and other skills besides shooting.
Whichever workout you choose, you'll be sure to get your grind on!
