People battling with their weight who are unable to do aerobic exercise can hit the gym instead and still see positive results.

Despite the commonly held belief is essential for weight loss, an Edith Cowan University (ECU) study conducted at the Exercise Medicine Research Institute (EMRI) has found resistance training can also have positive results—in conjunction with reducing .

Lead researcher and Ph.D. student Pedro Lopez said the findings showed resistance training can have a significant effect on fat mass, muscle mass and weight loss.

"Usually when we talk about obesity, or , we only hear about aerobic exercise," he said.

"This paper shows we can use resistance training and achieve meaningful effects with a diet based on caloric reduction. We can reduce body fat percentage, whole-body fat mass, body weight and BMI.

"If you're comparing the literature, these effects are similar to aerobic exercise with caloric restriction in adults who are overweight or obese."

Mr Lopez said it was important people battling obesity had options beyond just aerobic exercise to lose weight.

"This group may be uncomfortable by the prospect of 30 or 40 minutes on a treadmill or a bicycle," he said.

"They can injure knees, joints, ligaments and more because they have to carry their whole body weight during a lot of aerobic exercises."

Unique benefits

Mr Lopez said resistance training also catered to other important factors when looking to lose weight, such as building or preserving muscle mass.

"The study also showed was effective in avoiding losing when lowering the number of calories being consumed," he said.

However, Mr Lopez stressed the study was not a comparison between aerobic and resistance exercise.

Regardless of which people chose, they would also have to cut down on the calories.

"If you want to lose weight, you have to reduce your calorie intake."
