Join Nik for a meaty episode about the hamstring muscle group (Biceps femoris, Semitendinosus, and Semimembranosus). Here she gives real world examples from her days of teaching yoga on how "tight" hamstrings are making it hard to touch your toes in Forward Fold and why you don't need straight knees in Down Dog. Lastly, Nik gives another biomechanics lesson on muscle contractions (concentric, isometric, and eccentric), bringing in more examples from the gait cycle. Learn what happens when your posture leaves perfect alignment and how walking is basically nothing but a controlled fall...oh yeah, and why your hamstrings keep you from doing backflips every time you take a step. Origins, insertions, innervations, and actions are ALWAYS included. Chow down. This one takes a bit to digest.
