In 2009, Tim Ferriss set out to do something absurd.

He wanted to see if he could gain muscle faster than anyone thought possible. Without spending hours in the gym.

Most people train six days a week.

Ferriss trained twice.

Each workout was 30 minutes. He only did a few exercises. And he didn't change the plan once.

But here's the thing: He tracked everything. Sleep, glucose, insulin response, time under tension, rest periods, and muscle failure.

By day 28, he had gained 34 pounds of muscle. No steroids. No gimmicks. Just ruthless precision.

And while some still scoff at the title (The 4-Hour Body), the results were legit.

He'd proved something: You don't need to do more. You need to do what matters most, better than anyone else.
