I just got a call that the bookstore has a Graham-ish book in, so I hope to read more about the contraction there.<P>My teacher uses imagery including your teacher's punch in the gut, and vomiting, front muscles moving up while back muscles move down, being pulled back by your waistband, and originating from the pelvis, almost sexually. Not sure about the last one, if she meant a backwards pelvic thrust, but I didn't want to press the issue at the moment.
<P>Thanks for your advice. Trying to hold the entire spine rounded, and practicing on the soft carpet at hope did help some. When my back feels completely normal, I will practice some more, and also see if I can further develop my cheat to use my side. I am still concerned about other damage like pinching a nerve or disc. I should have titled my question differently, since if bone bruises heal fully, then that is not a big concern for me.<P>And thanks for the validation on the knee pads. As the only guy, a beginner, and a quiet person, I already feel a bit like the different/outside person. Add on being the only one in knee pads and whining to the teacher about not hurting my back.
