The York Plyo/ Set-up Boxes have been designed with athletes in mind. They have many uses, then main ones are being used as stackable Plyometric boxes for explosive training, step-up boxes for all over body conditioning, circuit based training & with the addition of the Beveled Technique Box, these are used for doing partial lifts (starting from a set height) such as cleans. This is particularly useful when limited movement is apparent in a lower limb through injury, but the athlete & trainer still feel they can lift the weight from an agreed height
