I have a question on the approach. Since my volleyball experience is very limited. What is a best drills for the approach? I am not sure if this is a good drill but I hung a boxing speed ball on the garage ceiling about 96 inches from the ground. I take a 3-step approach and try to contact the bag in the air with proper arm technique. However during the actual game my footwork gets all messed up and end up making mistakes. Mostly to early to ball where I am reaching back or mostly too late and only getting fingers on my hits. Since this is a rec play at the local gym, i don't get consistent sets. For some reason the setters are always setting the ball very tight on top of the net. Is this common? All inputs will be greatly appreciated. Thank you in advance for all the response.
