This is similar to
koto_ryu's tennis ball idea; underneath my pergola I have placed different sized balls E.g. tennis ball, soft small & medium size ball, foam ball etc in old stockings/panyhose and hung them at different heights & distance between each other under the pergola. You start of striking one then another and the aim is to react or dodge each ball so you don't get hit. It looks like an obstacle game with all the balls swinging like a pendulum. Its great hand-eye coordination, really tests your reflexes, really works up a sweat when your determined and is a whole lot of fun. I've been hit so many times but its great for a laugh within yourself anyway and teaches you to move faster!!!
