This video pretty much sums up our entire philosophy. Skill, Endurance, Strength; in that order. Why? Skill requires the largest diameter afferent (sensory) nerves to accomplish (Ia and Ib afferents from muscle and joint mechanoreceptors); they are the fastest pathways; Endurance comes from larger sized Type I (and sometimes Type IIa) endurance muscle, which are oxygen dependent (aerobic) and are rich in myoglobin, glycogen, mitochondria and capillaries; Strength last, because it comes from smaller, Type IIb fibers, and is largely glycolytic (depends on anaerobic respiration) and is dependent on the other 2 (skill and endurance).
When you take amazing skill and body awareness and combine it with strength and flexibility and control you can do these kinds of wild things.
