re: Chris Hemsworth's stunt double says he's struggling to keep up with the star's weight gain

I had a doctor explain it to me once


The act of taking steroids isnt what makes these people huge. He said taking steroids and changing nothing else about your workouts only will have a marginal effect

Where steroids help the huge growth, is when you couple it with a type A neurotic workout warrior. What steroids due is allow you to recover and push yourself harder and more often

So average dude that hits the gym 3 days a week isnt going to see monumental growth on roids because he isnt going to double and triple down on his workouts.

Now these type A bodybuilders and self indulged actors? They will take the roids and then push their body to new limits
