I came across this video last week and wanted to share it. It is gold. I think we have all played with foot position to target different areas of our calves, but who knew the secret is with our knees, not feet. I have done this twice and it really does work. I never locked out my knees before, but I am bending my knees more and I feel the movements in my outer calves more.
