I owe this to someone from the Dominican Republic: There needs to be a walking with ankle weights or wrist weights competition that pays money...The ankle weights OR wrist weights need to be very thinner and calibrated/inspected before the competition or a good chunk of people will collapse...

Also:

All ankle weights that you buy if you plan to wear it all day take 86% of the sand out of it and if you plan to walk everyday take between: 93% to 96% of the sand out of it, maybe more i dont know...
