Racquetball and legs

I played some racquetball last night with some friends and felt very good other than my lousy backhand.   Today, however I was pretty sore after doing the legs and back video after nearly two hours of racquetball the night before.  A couple students laughed at me when I tried to get up from my desk chair.  Its already 8:00 and we haven't even thought about doing the ab ripper x video.  It may have to wait until tomorrow.  Kenpo X tomorrow which is my favorite.
