💪Weightlifting Beats Running for Blood Sugar Control in Mice
Lifting Weights Wins Over Cardio for Blood Sugar Management
TL;DR
A new study finds weightlifting is more effective than running at controlling blood sugar levels and reducing fat in mice. Researchers saw better health benefits with resistance training, highlighting the importance of incorporating both exercise types for optimal results.
Researchers at Fralin Biomedical Research Institute found that resistance training outperforms endurance exercise in improving glucose tolerance and lowering insulin resistance in mice fed a high-fat diet. The study, published on October 30, 2025, highlights the superior health benefits of weightlifting over running for blood sugar control and fat reduction. Key findings include improved skeletal muscle signaling pathways that could inform new drug therapies for Type 2 diabetes. This research underscores the importance of a balanced exercise routine combining both resistance and endurance training.
Key Points
Study compared voluntary running and weightlifting in mice fed a high-fat diet over eight weeks
Resistance training reduced subcutaneous and visceral fat, improved glucose tolerance, and lowered insulin resistance
Running also helped clear excess sugar from the blood but was less effective than weightlifting overall
Researchers saw changes in skeletal muscle signaling pathways that could inform new drug therapies for Type 2 diabetes
Study published on October 30, 2025, in Journal of Sport and Health Science with DOI: doi.org/10.1016/j.jshs.2025.101100
Why It Matters
If you're managing diabetes or obesity, this study suggests a balanced exercise routine combining resistance training and endurance activities is more effective than either alone. For those on GLP-1 agonists, the research highlights that exercise programs can offer comparable benefits without side effects.
