Thanks for the tips - and I am starting a beginners yoga class Wed eve at my club - it will be a good hour after my personal training session so hopefully that won't be too much.

My hip flexors do seem to be starting to loosen - but not really on my right side where the knee is acting up. I still need all of the hip-flexor-stretching that I can reasonable get. Picturing to myself the position of my leg at the end of spinning class where we just did the quad stretch last night, I do seem to remember my leg being at an odd angle - which would certainly have caused an alignment problem and thus the pain.

All of this just encourages me to become even more aware of what my body is doing, especially where alignment is concerned. I am thankful my schedule is finally allowing me to go to the once/week beginners yoga class - and I have 5 free sessions in which to check it out
