lilli thank U so much for your response!! And believe me...I do challenge myself every time. I know in my heart and & body if I'm not sore a day or so after I've worked a certain group of muscles then I didn't challenge myself enough. I actually had some idiot tell me recently that I was lifting too heavy. My trainer/friend informed him that I was stronger that he thought I was and that the weight I was lifting was fine.

Again thanx so much for your advice!!
