Are we absolutely sure that Christian Bale actually isn't Batman?

The guy is a machine!

How is this Fitspo?  Yo-yo dieting is one of the worst things you can do to your body and stories like this tend to normalize it.

Some of them -- like Mila Kunis and Natalie Portman -- used nutritionists to slim down.

Others -- like Christian Bale and Hillary Swank -- developed strategies for bulking up.

OK but in every case the body transformation was for a role (aka a job), it was frequently quite grotesque, and it was temporary by design.  Fitness for real people is all about inhabiting the body you actually live in on a day by day basis... so for me, this article is the opposite of inspirational.  :(

You could read it another way.

Any body can be manipulated short term.

Longer term, it's important to establish good habits.
