It would be really tough explaining to them the mechanics of racquetball and teaching them the main positioning and techniques in playing. It is best if you would try harder not to lose your cool. Here are some effective tips that would surely help you succeed in your endeavor. First, explain to your students the concepts of missing the ball and crowding the ball. If the ball is moving to the back, get so far in front of it (at least a step) so you will have time and room to step forward into your setup position. Don t begin your forward swing with only the hands and arms. (There will be not much power to them.) Don t keep one knee straight when bending your knees. It is achieved by making a hard and high hit at the side wall making the ball hit the front then to the other side wall and finally back to the original side wall. If this offensive technique is properly executed the path of the ball will manifest a Z shape. It can be characterized by confusing bounces that can really heat up the opposing player. Power sources can be specified into primary and secondary forces. The primary force is triggered by elbow preparation in coordination with the hips. It is supported by a secondary power coming from leg drive. Shot selection is a key element. Employ the ceiling shot when the ball is chest high or higher. The short line is a solid red line that covers the court s width parallel to the back and front walls at a specific distance of 20 feet. The service line then parallels the short line having a 15-feet distance from the front wall. There are also two sets of lines perpendicular to the short and service lines located within the service box. Racquetball games require goggles to protect your eyes, no ifs and buts about it. They should be made of unbreakable plastic and need to be adjustable. (After a time, perspiration lubricates them and needs to be set securely again and again during the game proper.)
