I have a human cat toy
.a 6lb weight on a light pull long spring on a swivel arm / drum. When struck it flys. Then right back at you. I have impaired depth perception and I have to train my brain spatial relations. I also do Tia chi with a short staff instead of a sword. Balance is artificial if I close my eyes I tend to sway. This is like my goto for rehab after being hit.
All the scrapping I did when I was a kid 14.
40 years later I know why...
