Beyond mTOR: How AMPK and Myostatin Shape Muscle Growth
Muscle growth is governed by a three-way balance between mTOR, which drives protein synthesis; AMPK, an energy sensor that suppresses anabolism; and myostatin, a genetic brake on muscle growth. Understanding their interplay with training and nutrition is key to optimizing hypertrophy.
