Millerfarm; your wife may want to try taking Magnesium Citrate to see if it helps.
And it only takes about 15 minutes!
OP, in all honesty, a good coach is likely the only thing that your wife would need. It seems as though she wishes to train, and a solid coach who deals with people with training related issues often would likely be worth the investment.
The Citrate made just as much sense.
