Place 3 cones one on the free throw line and the other two next to it on the right and left side about a metre and a half away from the central cone.
Start from the right cone do a right hand layup grab your rebound and then circle around the central cone and do another right handed layup garb the rebound again and circle around the cone on the left side this time doing a left handed layup grab the rebound and circle around the central cone again doing another left handed layup then circle around the right cone and repeat until you have made 15 layups all together
