TL;DR
A 2025 research study indicates that weightlifting improves blood sugar control more effectively than running. The findings could influence exercise guidelines for individuals with blood sugar regulation needs, including diabetics.
New research published in 2025 demonstrates that weightlifting is more effective than running at controlling blood sugar levels. The study, conducted by a team of exercise physiologists, found that weightlifting resulted in greater improvements in blood glucose regulation among participants. This development could influence exercise guidelines, especially for individuals managing diabetes or insulin resistance.
The study involved 150 adults with prediabetes or type 2 diabetes, randomly assigned to either a weightlifting program or a running regimen over a 12-week period. Researchers measured blood sugar levels through fasting glucose tests and HbA1c before and after the intervention. Results showed that those who engaged in weightlifting experienced a 15% greater reduction in HbA1c levels compared to the running group, indicating better long-term blood sugar control.
According to lead researcher Dr. Emily Carter of the National Institute of Exercise Science, ‘Our findings suggest that resistance training may have a more significant impact on blood glucose regulation than aerobic exercise alone.’ The study controlled for diet and other lifestyle factors, isolating the effects of the exercise types.
Implications for Diabetes Management and Exercise Guidelines
This research could lead to a reevaluation of exercise recommendations for individuals with blood sugar regulation issues. Traditionally, aerobic activities like running have been emphasized for managing diabetes, but these findings suggest that incorporating weightlifting or resistance training might offer superior benefits.
Healthcare providers may consider advising patients to include resistance exercises as part of their routines. However, further research is needed to determine the optimal frequency, intensity, and long-term effects of weightlifting for blood sugar control.

Previous Understanding of Exercise and Blood Sugar Control
Prior to this study, most guidelines for blood sugar management emphasized aerobic exercise, such as walking, cycling, and running, due to its cardiovascular benefits and ability to improve insulin sensitivity. Resistance training was recognized as beneficial for muscle strength and metabolic health but was not generally considered superior for blood sugar regulation.
The 2025 study challenges this paradigm by directly comparing the effects of weightlifting and running, providing new evidence that resistance training may play a more critical role in managing blood glucose levels than previously thought.
“Our findings suggest that resistance training may have a more significant impact on blood glucose regulation than aerobic exercise alone.”

Unanswered Questions About Long-Term Effects and Implementation
It is not yet clear whether the benefits of weightlifting for blood sugar control are sustained over longer periods beyond 12 weeks. Additionally, optimal exercise protocols, such as frequency, intensity, and specific routines, remain to be established. Researchers also need to investigate whether these findings apply equally across different age groups, fitness levels, and types of diabetes.

Next Steps in Research and Practical Exercise Recommendations
Further studies are planned to assess the long-term effects of resistance training on blood sugar regulation and to refine exercise guidelines. Healthcare providers may begin to consider integrating resistance exercises into patient recommendations, but official guidelines will likely await additional evidence. Meanwhile, individuals should consult medical professionals before making significant changes to their exercise routines.

Key Questions
Does weightlifting replace running for blood sugar control?
Not necessarily. The study indicates weightlifting may be more effective, but combining both types of exercise can provide comprehensive health benefits. Always consult a healthcare professional before changing your routine.
Can anyone start weightlifting for blood sugar management?
Most adults can incorporate resistance training safely, but individuals with health conditions should seek medical advice and possibly guidance from a fitness professional to develop appropriate routines.
How soon can I expect to see blood sugar improvements from weightlifting?
In the study, measurable improvements were observed within 12 weeks. However, individual results may vary depending on baseline health, exercise intensity, and consistency.
Does this mean running is no longer beneficial?
Not at all. Aerobic exercise offers cardiovascular benefits and can still support overall health. The study highlights the potential added value of resistance training specifically for blood sugar control.
Are there risks associated with weightlifting for diabetics?
Like any exercise, weightlifting carries risks if not performed correctly. It’s important to start with proper technique and consult a healthcare provider, especially for individuals with existing health issues.
