A similar thread here
, from a couple of years ago. The thread is titled, "Slacklining: Vestibular, working memory & more."
I try to do balance exercises daily. I have a number of balance devices including an indoor slackline frame that I use most mornings. I also have a ring and sphere balance board - seen here
from the underside. I have a Skillboard
on order. Basically the same idea, but no ring on the underside to constrain the ball. I also use KAATSU
bands during exercise that make everything much harder as they restrict venous outflow from the limb the band is on. Hence it makes even lifting light weights hard after you do, say 30 reps. I do this and then try to balance. A fairly detailed description of what is generically called Blood Flow Restriction Training is here in this IHMC presentation.
