>>Lee Priest, an Australian bodybuilder, sometimes weighs 300 pounds at
5'4'', in muscular shape! Lee Priest at this 5'4" 300 pounds has knees
in excellent health!<<

He could be her son for one.
Him achieving 300lbs with 2% to 3% body fat on a 5'4" frame (without
taking anything away from him) comes from Overuse of steroids, insulin,
diuretics etc...

Not a good comparison

However try catching WORLD'S STRONGEST WOMEN on ESPN. There you will see
women that size with very little fat to moderate fat in excellent cardio
shape.
