Great stuff from AFC Ajax academy. A fun drill and something different for kids to do to develop timing and jumping mechanics in response to an external stimulus. This is the age to really start on all the 'agility' training. As the kids get older the 'SAQ and traditional agility' work becomes almost redundant as you are not actually changing the mechanics to make the drills effective you are just putting players through random circuits and expecting those changes will transfer to the field.
