When guys who've never lifted weights before start training, using super detailed muscle scans and taking strength readings twice helps scientists measure changes more accurately—so they can tell for sure if bigger muscles mean stronger muscles.

Muscle Growth Is Very Strongly Correlated with Strength Gains after Lower Body Resistance Training: New Insight from Within-Participant Associations

Cohort Study

Human

2025 Dec 1

This study used super detailed scans and careful strength tests on guys who had never lifted before, and found that when their muscles got bigger, they also got much stronger — and the precise measurements made it clear this link is really strong.
