How did herschel walker get so big by just doing pushups, dips and pull-ups?

I heard that this guy never touched a weight in his life. Then how did he get so big? There are some people who say he had great genetics, but cmon, even if he did, he would still have to a have a proper training routine to get strong and be a good football player. Even gifted people have to work hard.

So can you really get that big by doing a thousand pushups like he did?

Resistance training is training the muscle through any form of resistance. It only takes a little bit of history to see that the current trend of lifting weights and gulping supplements isn't the only way to get big. You can see statues and depictions dating thousands of years to the past of individuals who built large, strong physiques.

Genetics certainly play a role. However, any type of resistance can help force the muscle to grow. There is no need to ever bench press a single barbell - you can certainly provided adequate resistance through calisthenics, yoga, and other training routines. This, combined with proper nutrition (you must eat big to grow big) is the only stimulus needed to build appreciable bulk over time.

I don't know but I've met him before at dfw airport with his tiny wife and got his autograph. I know he's had ballet training.
