But range of motion (ROM) isn't just a mobility concern; it's one of the direct stimulators of muscle growth. How far you move a muscle under load has a measurable effect on how much it grows, and improving your flexibility can directly expand your capacity to build muscle. Here's how ROM, flexibility, and hypertrophy connect — and what to actually do about it. Why Range
