For those of us who have been following skiing since the nineties or earlier, no doubt you have seen this Vagard Ulvang training video.  While it is close to 30 years old it is interesting to look back and see how much the sport of skiing has changed and how training has changed.  Its pretty obvious there have been advances in equipment and technique, especially around upper body movements. It is also interesting to see that in some ways training has not changed as much as we think.
