I used the SIDE of my thigh in order to find more fat and found that worked well. the top side of your thigh has precious little fat and its too easy to nick into the muscle. go over to the side, grab a hand ful of yummy fat and STAB! ta da no more sore legs. I have heard of folks using the inner thigh but i never ever could find enough courage to do it there. EEEK!

I hope its feeling better now.
