When you get stronger holding a position (like pushing against a wall), your muscle size matters more — but when you’re moving (like kicking a ball), how hard you activate your muscles matters more than how big they are.

Anatomical and Neuromuscular Determinants of Strength Change in Previously Untrained Men Following Heavy Strength Training

Cohort Study

Human

2019

This study found that when untrained men get stronger by lifting weights, their static (isometric) strength improves mostly because their muscles get bigger and change shape, while their dynamic (concentric/eccentric) strength improves more because their nerves get better at telling muscles to work hard.

Similar Assertions

When young men do isometric leg exercises for 12 weeks, their thigh muscles get bigger—and that bigger muscle size helps explain about 1 in 5 of their strength gains, even if their nerves aren’t getting better at telling muscles to work harder.

Just because certain muscle traits make someone strong right now doesn’t mean those same traits will help them get stronger from training—what matters for improvement is different.

Just because your muscles get bigger from lifting weights doesn't mean you'll get much stronger — the two don't really go hand in hand.

Whether you do CrossFit or lift weights regularly, your thigh muscles end up about the same size after years of training.

Even though the deep thigh muscle (vastus intermedius) isn’t the biggest or most active, changes in how its fibers are angled are surprisingly linked to how much stronger people get during dynamic leg movements.
