I don’t have a firm set in stone attitude towards skin folds, although there are many fitness coaches in rugby that live and die by the caliper readings, if a player is carrying a bit but still is performing on the track I am happy with this but if there level of fatness is adversely effecting their ability to do the job on the paddock then we will change a few things and monitor more closely, and too true I have seen some big boys 120 deliver in a 3km time trial, and also be very explosive overe 10 metres as well, but with the new rules I do believe that aerobic fitness demands has increased a wee bit, but not too much to considerably alter our overall fitness plan, power to weight is the key, ashley
