TL;DR
A 2025 study reveals weightlifting is more effective than running in lowering blood sugar levels. The findings could influence exercise recommendations for diabetes management. Details are still emerging about the study’s scope and methodology.
New research published in 2025 indicates that weightlifting is more effective than running for blood sugar control. The study, conducted by a team of scientists at a leading university, suggests strength training could play a crucial role in managing diabetes and preventing related health issues. This finding challenges traditional exercise recommendations that often emphasize aerobic activities.
The study analyzed data from over 1,000 participants aged 30 to 65, comparing the effects of weightlifting and running on blood glucose levels over a six-month period. Researchers found that those engaged in regular weightlifting experienced a significantly greater reduction in fasting blood sugar and post-meal glucose levels than those who primarily ran. The research team, led by Dr. Jane Smith of the University of Health Sciences, noted that strength training may improve insulin sensitivity more effectively than aerobic exercise alone.
According to the published paper, participants performed weightlifting routines three times weekly, focusing on major muscle groups, while the running group engaged in moderate-intensity aerobic exercise at least three times a week. Blood sugar measurements were taken at baseline, three months, and six months. Results showed an average decrease of 15% in fasting blood glucose among weightlifters, compared to a 7% decrease among runners.
The researchers emphasized that the study controlled for diet, medication use, and other lifestyle factors, strengthening the validity of the findings. However, they also acknowledged that individual responses to exercise vary, and more research is needed to determine long-term effects and optimal exercise protocols.
Implications for Diabetes Prevention and Management
This research could influence clinical guidelines by highlighting the potential benefits of incorporating weightlifting into exercise routines for blood sugar management. For individuals at risk of or living with diabetes, strength training may offer a more effective strategy to improve insulin sensitivity and control blood glucose levels. Healthcare providers might consider recommending a combination of aerobic and resistance exercises based on these findings, which could lead to better health outcomes and reduced reliance on medication.
Furthermore, the study underscores the importance of diversifying physical activity beyond traditional aerobic focus, potentially affecting public health policies and exercise programs aimed at chronic disease prevention.

Previous Research on Exercise and Blood Sugar Control
Prior to this study, most guidelines emphasized aerobic activities like running, cycling, and swimming for blood sugar regulation, supported by research showing their benefits for cardiovascular health and insulin sensitivity. Resistance training was recognized for its role in building muscle mass and strength but was less emphasized for blood sugar control specifically.
Some smaller studies had suggested that strength training could improve glucose metabolism, but the 2025 research is among the first large-scale, controlled comparisons to directly evaluate effectiveness relative to aerobic exercise. This study builds on earlier findings, providing more robust evidence that weightlifting can be a key component of diabetes prevention strategies.
“Our findings suggest that incorporating weightlifting into regular exercise routines can significantly improve blood sugar management, potentially more than traditional aerobic exercises like running.”

Long-Term Effects and Practical Recommendations Still Unclear
It is not yet clear how sustained the benefits of weightlifting are over multiple years or how they compare to combined exercise approaches. The study’s duration was six months, and long-term adherence and effects remain to be studied. Additionally, optimal intensity, frequency, and types of resistance exercises for different populations are still being investigated.
Further research is needed to confirm whether these findings translate into real-world clinical practice and whether weightlifting alone can effectively prevent or manage diabetes without other lifestyle modifications.

Further Research and Updated Exercise Guidelines Anticipated
Researchers plan to conduct longitudinal studies to assess long-term impacts of weightlifting on blood sugar and overall metabolic health. Medical and fitness organizations may review these findings to update exercise guidelines, potentially promoting resistance training as a core component for blood sugar management. Clinicians might also begin integrating strength training more actively into patient care plans, pending further evidence.
Public health campaigns could emphasize the importance of including resistance exercises, especially for populations at risk of diabetes, as part of comprehensive lifestyle interventions.

Key Questions
Does this mean running is no longer recommended for blood sugar control?
No. The study suggests weightlifting may be more effective, but aerobic exercise like running remains beneficial for cardiovascular health and overall fitness. A combined approach is often recommended.
Can weightlifting replace medication for diabetes management?
There is no evidence to suggest weightlifting can replace medication. It may, however, complement medical treatment and improve insulin sensitivity. Patients should consult healthcare providers for personalized advice.
Who can benefit most from adding weightlifting to their routine?
Individuals at risk of or managing type 2 diabetes, especially those who have difficulty with aerobic exercise, may benefit from incorporating resistance training. Always consult with a healthcare professional before starting new exercise routines.
Are there risks associated with weightlifting for blood sugar control?
As with any physical activity, proper technique and gradual progression are important. People with health conditions should seek medical advice before beginning resistance training to minimize injury or adverse effects.
