But for the vast majority of us, I believe Efrons exploits shouldnt be used as a yardstick.

How hard was it to look like that?

Efron was asked onThe Kelly Clarkson Show.

A little bit, he answers with a wry chuckle.

[Obtaining Von Erichs physique] was a singular focus for months.

And your life goes out the window during prep, he adds in an interview withVariety.

Efron says his intense exercise regime also helped him get into the mindset of the man he was portraying.

I soon found out, as Efron himself says in his Mens Health interview, thats not really attainable.

This was reinforced by Chris Hemsworths long-time trainer Luke Zocchi when I spoke to him last year.

Months before shooting movies like Thor, Zocchi knows the exact day crews will be capturing a shirt-off scene.

How he prepares Hemsworth is comparable to getting him ready for a bodybuilding show.

This doesnt mean you should avoid lifting weights, or any other form of exercise for that matter.

Im not a professional athlete or actor far from it.

If youre reading this, its likely you arent either.

The only purpose exercise needs to serve in our lives is to improve them.

Train for fitness, function, and fun.

And if it makes you miserable and you want to stop, thats okay too.
