I'd happily trade my legs in for newer models. No matter how much work I do without stirrups and other strengthening exercises, I cannot retain the muscle tone in my 46 year old legs. I can build up legs of steel, and within 3 days of no intense work, it's gone, and all I'm left with is muscle fatigue. Are there any foods that help with this? I have no interest in external vitamins or organic supplements. There are far too many studies out there showing how many of those products are as advertised.
