One of the more useful tools I’ve been using in the past few months is the wrist roller I knocked up a while ago. This consists of an axe-handle, and a length of heavy-duty chain pinned to the centre of it. Weight plates are connected to the other end of the chain, which is looped through the hole of each plate and attached to itself with a short bolt + nut. Simple, effective and handy.
Recently I’ve been using the roller for Good Mornings, with the aim of keeping the weight in front of my chest rather than behind my neck. This seems to be doing the job nicely.
