Any ashiatsu therapist who loves to do seated work will tell you that you need to make sure you stretch your hip flexors. I personally often can spend 20-30 minutes doing seated work during a 90 minute session (depending on the client’s needs.)
You need to make sure you keep your hip flexors loose in order to do this or you’ll end up walking like Quasimodo.
This move is like your typical runner’s stretch, but it has an added component: the side stretch.
