Benren:
Thanks, what about the pelvis/waist, should I pivot my pelvis forward, and rest on my coccyx almost? Its the second time I get lower back aches from this routine so I must be doing something wrong. I probably am not holding my core tight enough, just want to know if something else might help too. I hate to have to take an extra day off or two because of pain.
Pelvis/waist should be in a nurture position. it could also be caused from a weak core. the stronger your core gets, the less pain you will have.
