That her figure is not because of her age.
She just wants to have a figure like every other woman of her age and stop being a superfit dancer.
It happens to many professional athletes, after too much working out they just hate dieting and hitting the gym.
Maybe she has Joint problems but I think she could still be lean just by doing aerobics and dieting.
When you are a global fitness model for 30 years and you have you own Gym Brand is somehow strange to be just in an average shape for a 60 years old lady.
