I worked at 3 different gyms and was a personell trainer. What did it get me,,, laid every day, 3 knee replacements with 2 more the 30th of this month, 5 herinated dics and aches and pains a 60 year old should not have. When I turned 40 the ortapedic surgeon said I had the bones and joints of a 70 year old. But I had 16 inch biceps, oh and got laid every day. Hooters hired me to train their girls from Clearwater. Mr Brodski the owner from Davenport, Iowa thought I neede to get laid every day. Now I have metal in places Arnold never thought of. Let your daughter know to keep those knees wraped and tighten that belt. New versions of knees have 30 year warranties now. She starts now she,, you,,, can get your monies worth. More kneedles in the knees the 30th,,, just what I wanted for Christmas.
