Strong v swole: the surprising truth about building muscle
SMRTR summary
Current research reveals that mechanical tension, not muscle damage, is the primary driver of muscle growth. When lifting heavy weights or performing enough repetitions near failure, physical tension stretches muscle cell membranes, triggering specialized sensors that activate muscle protein synthesis to build new tissue. This means soreness isn't a reliable indicator of effective training, and significant muscle growth can occur without extreme pain or pushing to absolute failure.
