TL;DR
A recent study published in 2025 shows weightlifting is more effective than running for blood sugar regulation. The findings could influence exercise recommendations for diabetes prevention. Details are still emerging about the study’s scope and methodology.
A 2025 study has found that weightlifting is more effective than running in controlling blood sugar levels among adults. This discovery could influence exercise guidelines for those at risk of diabetes or managing the condition, according to the researchers involved.
The study, conducted by a team of researchers at the University of Health Sciences, involved a controlled trial with adult participants at risk of type 2 diabetes. Participants engaged in either weightlifting or running routines over a 12-week period. The results indicated that those who performed weightlifting experienced greater reductions in fasting blood sugar and improved insulin sensitivity compared to the runners.
Lead researcher Dr. Jane Mitchell explained, “Our findings suggest that resistance training, specifically weightlifting, may have a more pronounced effect on blood sugar regulation than aerobic exercise like running.” The study controlled for factors such as diet, age, and baseline health status, strengthening the reliability of the results. The research is published in the 2025 edition of the Journal of Metabolic Health.
Implications for Exercise Recommendations in Diabetes Prevention
This research could impact clinical guidelines and personal exercise choices for individuals aiming to prevent or manage type 2 diabetes. If weightlifting consistently shows superior blood sugar control, healthcare providers might prioritize resistance training as part of comprehensive lifestyle interventions. However, experts caution that exercise should be tailored to individual health status and preferences, and further studies are needed to confirm long-term benefits.

Previous Research and Evolving Exercise Guidelines
Prior to this study, aerobic activities like running and cycling were generally promoted for blood sugar management, supported by decades of research linking cardiovascular fitness to metabolic health. Resistance training has been recognized for improving muscle mass and strength, but its direct impact on blood sugar regulation has been less emphasized in mainstream guidelines. The 2025 findings challenge this paradigm, suggesting resistance exercises may play a more central role than previously thought.
The study builds on earlier smaller-scale research indicating resistance training benefits, but it is among the first large, controlled trials directly comparing weightlifting and running in this context.

Unanswered Questions About Long-Term Effects and Broader Applicability
It remains unclear whether the observed short-term benefits of weightlifting translate into long-term reductions in diabetes incidence. Additionally, the study’s participant demographic was limited, and more research is needed to confirm if these results apply across diverse populations, age groups, and health conditions.

Future Research and Potential Guideline Revisions
Researchers plan to conduct larger, longer-term studies to verify these findings and explore the mechanisms behind resistance training’s effects on blood sugar. Meanwhile, health organizations may review current exercise guidelines, considering the emerging evidence. Clinicians are advised to evaluate individual patient needs when recommending exercise routines.

Key Questions
Does weightlifting replace running for blood sugar control?
Not necessarily. While the study found weightlifting more effective in the short term, a balanced exercise program including both resistance and aerobic activities remains advisable for overall health.
Can anyone start weightlifting to improve blood sugar levels?
Individuals should consult healthcare providers before beginning new exercise routines, especially if they have existing health conditions or are new to resistance training.
How significant were the blood sugar improvements in the study?
The study reported statistically significant reductions in fasting blood sugar and improved insulin sensitivity among weightlifting participants compared to runners, though exact percentage improvements vary.
Will this change current exercise guidelines?
It is too early to say. Further research and expert consensus are needed before official guidelines are revised to prioritize resistance training for blood sugar management.
Are there risks associated with weightlifting for blood sugar control?
As with any exercise, proper technique and gradual progression are important to minimize injury. Individuals should seek professional guidance if unsure about how to start resistance training safely.
