Flexibility is often dismissed nowadays because it is „just" passive range of motion throughout your joints, depending for example on tissue suppleness. (Mobility in contrast is active flexibility, a combination of tissue suppleness for expanded ranges of motion, stability and neurological control.)
Passive refers to the fact, that flexibility needs an outside source like gravity or in this case, the momentum of the dyno.
His flexibility allows @ヤン・ホイヤー to absorb the swing by smoothly matching circular and parabolic trajectories at the point of contact in every joint of his body.
With a more rigid frame he wouldn’t have gone to bouldering semis @innsbruck2018 today. #climbingtechniqueofthe21stcentury #itaintmeanathingifitaintgotthatswing #climblikeagirl #bouldering #acrobaticclimbing #climboid
