Tight leg muscles can pull your knee out of ideal forward hinging. I'm stretching all 4 sides of each leg and using magnesium brine spray to relax the muscles.
-Put foot on couch and inner thigh stretch
-Sit legs flat on ground and try to touch toes (loop towel below toes and pull to help)
-Do the 'couch stretch' shin lines up on back of couch, lean back towards foot
-For outer leg, put right leg over left hip/shoulder and loop towel below toes with a slight twist so that it's pulling the toes in as you stretch
