In some cases, weightlifting can be more beneficial than exercises like cardio. According to a new study conducted at the University of Virginia, weightlifting is a more effective way to control blood sugar than doing cardio.
This study was conducted on rats under the leadership of Jane Yan. Those who lifted weights recorded lower blood sugar levels than those who ran on wheels. Interestingly, apart from blood sugar, other indicators like muscle and cardiovascular fitness showed no improvement from weight lifting.

Weightlifting vs. Cardio: How was the study conducted?
This study was published in the Journal of Sport and Health Science. Lab rats, who were fed a high-fat diet for eight weeks, were divided into three groups – one was kept sedentary, another was made to lift weights and the remainder were made to run.
Not surprisingly, there was less weight gain in the two exercise groups compared to the inactive exercise groups. However, those who gained weight had better insulin sensitivity and glucose tolerance, which are important parameters in assessing a person’s risk of developing diabetes.
It was found that weight lifting did not increase muscle size. Instead, changes were happening inside the cells. Lifting weights reduced visceral and subcutaneous fat, which may affect the recommended exercises for controlling blood sugar.

Benefits of strength training
For a very long time, people have associated weightlifting with bodybuilding and muscle gain. However, the benefits of strength training go far beyond this aspect.
According to an article on Penn Medicine’s website, this type of exercise has great benefits for a person’s overall physical and even mental health.
The article quoted Dr. Benjamin Snell of Penn Medicine as saying, “There is strong evidence that exercise, including weight training, can help prevent and treat depression.”
“With strength training, you’re not only boosting your muscles, but your bones as well,” Dr. Andrew Brough tells the outlet. “You can improve your bone density and create more flexibility in your joints, and improve your mood.”
So, the next time you’re at the gym, don’t be content with just walking or running on the treadmill. Try lifting some weights, this will help you lose weight, keep your joints and bones healthy and also improve your mood.
