Of course none of these benefits will come without dedicated practice. Try to commit to doing the exercises everyday during summer. Or do them everyday after school for a month. See if your coach will buy a couple ladders for the basketball team and commit to doing them before or after practice.
Frugal tip: If you don’t have money to buy an agility ladder, then tape on the ground with masking tape. I didn’t have the cash to make one when I was young, so I tapped one to my garage floor.Check out the videos posted for exercises. Get to stepping!
