The Claim

Even if your muscles don’t get much bigger from lifting weights, your body still improves how it uses energy, like making your muscles better at burning fuel efficiently.

Even if your muscles don’t get much bigger from lifting weights, your body still improves how it uses energy, like making your muscles better at burning fuel efficiently.

See the scientific wording

Resistance training increases expression of aerobic metabolism and mitochondrial gene networks in older adults, independent of muscle hypertrophy, suggesting resistance exercise can enhance metabolic fitness even without significant muscle growth.

What the research says

1 study

  1. Study: Muscle Transcriptional Networks Linked to Resistance Exercise Training Hypertrophic Response Heterogeneity.

    Even if older adults didn’t get much bigger muscles from weight training, their muscles still made more of the proteins needed for efficient energy use—like improving the engine’s fuel efficiency without adding more parts.
