Claim Breakdown:
📝 Fact Check: This is a popular gym myth that doesn't hold up to scientific scrutiny. Muscle growth, or hypertrophy, is primarily a local process. 🏋️♂️ This means the muscles that grow are the ones you directly train. While training large muscle groups like the legs can cause a small, temporary increase in anabolic hormones (like testosterone), the evidence shows this systemic effect is insignificant for causing growth in untrained muscles like the chest and biceps. You can't squat your way to bigger arms; you need to train your arms directly. 💪
