As a result of flexibility within my hip flexor/groin region, I've been doing the Seal of Yoga (aka Yoga Mudra) exercise with a modification. That is, I've been placing my feet together instead of sitting cross-legged. If not for this modification, the only stretch I'd get (assuming that is at least part of the point) is a slight one in the buttock corresponding to the leg resting atop the other. WITH this modification, I feel a much more thorough stretch throughout my inner thigh & groin region.
It didn't occur to me until today that there might be a specific reason for doing the Yoga Mudra exactly as described. If anyone could please chime in with an answer, I'd be appreciative.
Thanks,
Greg
