Bodybuilding legend Arnold Schwarzenegger ‘s all about protein, but carbohydrate intake might be the missing puzzle piece to more growth. In a recent Arnold’s Pump Club newsletter, published on August 27, 2025, he discussed the muscle-building advantages of extra carb intake.

“If you’ve been laser-focused on hitting your protein goals while cutting carbs to build muscle, this might flip everything you thought you knew about gaining size.”

Having conquered the Mr. Olympia throne for seven years, Schwarzenegger is a living legend, still helping grow bodybuilding. In retirement, his involvement in the sport hasn’t waned; he hosts the annual Arnold Sports Festival every year in March, celebrating fitness and health.
