I saw in Transport Talk that TR Group has co-produced a free online course for truck drivers and forklift drivers, etc (see here: https://transporttalk.co.nz/news/free-course-helping-truckies-stay-healthy). It's a dietitian presenting it from the angle of a driver, plus some interviews from truck drivers about their experiences - all done with video, and quite accessible.
What other things do you do for your team as regards helping with diet, hydration, etc? We have a urine colour chart and we run a biggest loser competition, but we probably have too many cakes and pies for celebrations
