Your core strength comes from your lower stomach muscle region. The area is best identified by simply trying to pull you stomach in away from your belt. If you can train yourself to ski with this middle body strength you'll be better supported and ready for the absorption. The first thing to give when skiing is always the waist.

Getting this middle body tension, also known as 'retained tension' as we spoke about earlier, to the right degree is best quantified on a numbers scale.
