Most people don't consider how dice weight and grip play into repetitive strain. @grayc27's point about stretches is good, but using lighter dice or alternating hands could help too. I've seen tournament players use foam dice for longer sessions to cut down on impact. It's all about small changes to avoid injuries like tennis elbow.
