Do you think you know everything that’s going on during the Leg Circles on the Reformer? Shari Berkowitz explains how much you should be pushing into the straps when you’re frogging and circling. Do it with her and you’ll be amazed at how your hamstrings and back muscles join the party and assist your movement. Visit Shari for teacher training, workshops and lessons at The Vertical Workshop. Our thanks to Shari’s student Roccio Cárceles and The Contrology Cohort in New York City where this was filmed.
