Stretching your muscles during exercise helps, but working out hard, doing enough reps, and showing up regularly matter way more.
Scientific Claim
Total training volume, training intensity, and consistency are more significant determinants of muscle hypertrophy than the specific muscle length at which training occurs.
Original Statement
“It is crystal clear that the muscle length you train at is certainly not the most important factor for growth. Training hard enough, performing sufficient volume, and just plain old consistency are more important.”

Even when people did leg curls with their feet pointed different ways, their muscles grew the same — proving that how much and how hard you train matters more than exactly how you position your foot.
Volume Load Rather Than Resting Interval Influences Muscle Hypertrophy During High-Intensity Resistance Training
The study found that lifting heavier weights more times (total volume) made muscles grow bigger, no matter how long you rested between sets — so what matters most is how much you lift overall, not tiny details like muscle position.
