WristWeights.co.uk Wrist weights are used in place of holding dumbbells (or to supplement them) or other hand-held weights as a way of adding leveraged resistance to the movement of the arms. Like ankle weights, practicing explosive movements is not advised, and if done, should be approached gradually, with acceleration before full extension, and also reduced gradually, to avoid over-extension injuries. Wrist weights are advantageous in that they do not require a strong grip or wrist extension for added arm resistance like held hand weights do. A disadvantage is that the tightness required to stop movements could possibly increase the damage in those with carpal tunnel syndrome. Auction is ending in few hours.
