Doing the same movements over and over is not a good alternative to prevent injuries. You should follow these OSHA suggestions here, instead:
■ Break up tasks to avoid continuous cutting or slicing.
■ Don't work with the hands or wrists held in a bent or twisted position.
■ Keep knives sharp. Ask your manager or a more experienced co-worker for assistance when learning to sharpen blades.
■ Use different knives to see which one is more comfortable to use.
■ Keep all slicers, cutters, and other equipment sharp and in good condition. Dull or improperly working equipment requires more force to operate.
Now watch this entertaining video from Bob and Brad with some exercises to help avoid wrist strains. Go from 1:38 to 3:25.
