Mike,
Thanks so much for responding. This is by far one of the most useful threads on this site.

1. As far as reps, I'm assuming you now do 2 sets (of 10 reps each) per leg: front, side, back? I'll follow your advice and see what happens for me. (Also will do strength work on ab+adductor pull downs with resistance).

2. Any stretching advice for keeping my toes pointing down and out of the way for proper strike in a roundhouse kick? My toes don't like to get out of the way and are constantly getting messed up in RH kicks.
