I skied about 90 days last year and did not stretch off after once. Result? Chronic lower back pain due to my hamstrings being retarded tight. My leg could not even reach 45 degrees off the ground. It has taken me a summer of extremely painful stretching for 20-30 mins each day and a fair few physio sessions to get to a reasonable flexibility. 10 mins out of your day to stretch before and after skiing is nothing.
