Chris Pratt Reveals Ultimate Muscle-Building Secret.

Chris Pratt, inspired by his father-in-law Arnold Schwarzenegger, shared his secret to building muscles on Instagram. He believes that pushing one's muscles until they fail is the key to building a better physique. This method may lead to injuries, but it tears and rips the muscles, leading to soreness and rebuilding, ultimately strengthening and enlarging the muscles. Pratt and Schwarzenegger share a friendly relationship and often bond over exercises and cigars.
