My recovery included six weeks of non-weight bearing on the left leg. For an active person like me, replacement activities were needed. This is where your expertise came in; maintaining upper body fitness for the upcoming Nordic ski race season was a priority. The Spincore you had been developing was the perfect balance of strength and endurance exercise for the upper body and core combined. The simplicity and the adjustable resistance made it easy to use in any setting and build on the challenge as I progressed.
