Hey I've got a new favorite exercise. I'm currently doing about 100 a day (on a good day), hope to pump it up to 500 within a year. It's working my knees, but I think in a postive way.
So do you guys relax the calf muscles, or keep the ankles locked? I've been doing more locked, but I thing I've figured out that you're actually supposed to keep them relaxed.
