Here you go. Have a look. Can you do this? If you can you have excellent control on your volley. If you can't, try on the bounce or regular figure 8 volleys first and build up to it.
I hope you enjoyed this exercise. I'm open to suggestions for the name of the exercise. I have a lot more skill challenges coming soon! I will post #3 later this week. Follow my Youtube channel at cchsquashpro for more skill challenges and other squash related videos.
