The following research investigated if different ways of exercising can make a difference in your waist circumference (Dor-Haim H, et.al., 2022).

The participants were men who were recovering from myocardial infarction and was either put on a moderate-intensity continuous-aerobic training program, or aerobic interval exercise combined with alternating sets of resistance training (super-circuit training).

The researchers wanted to compare the effectiveness of both type of exercises on resting electrocardiographic, ECG; and heart rate variability, HRV and also changes in waist circumference.

They found that participants in both groups improved their ECG and HRV, but only the group doing super-circuit training had significant improvements in waist circumference.
