In adults with obesity, doing aerobic exercise for ten weeks without any other changes leads to measurable decreases in body weight, BMI, and body fat percentage.

In adults with obesity, 10 weeks of cardio exercise improves metabolic health markers, and when combined with resistance training, it still improves metabolic health. Resistance training alone increases muscle strength, while cardio alone reduces body weight and fat percentage.

Engaging in consistent cardio workouts, such as running or cycling, for four weeks is associated with a decrease in the proportion of body weight that is fat.

In young women with a BMI between 25 and 27, participating in supervised group aerobic exercise three times a week for 12 weeks leads to measurable decreases in body weight, waist size, and body fat, along with an increase in muscle mass.

In adults with obesity, doing only aerobic exercise for ten weeks leads to a measurable drop in the lower number of blood pressure readings, without needing strength training.

For adults with overweight or obesity, doing 30 minutes of cardio and 30 minutes of strength training three times a week for a year has the same effect on overall cardiovascular risk as doing 60 minutes of cardio alone.
