Anorexia Pictures Before And After A Question For Those Who Recovered From Anorexia?

A question for those who recovered from anorexia? - anorexia pictures before and after

Hello in recovering from anorexia and work to strengthen the back muscles. I showed my personal trainer, a picture of me two years ago asked if I could back muscles. It was not convincing and could me a definitive answer. Can not someone who has to anorexia and the loss of large amounts of muscle mass, could make muscles again? If so, how long it takes does not look as loose as it used to? Thank you to everyone who can help
