In this research, 37 adults underwent 12 weeks of aerobic training. All participants, prior to the study, were sedentary and overweight or obese [1]. Fitness was assessed prior to the study starting, and at the end too.

Half of the group just participated in the exercise programme, while the other half took 40 mg of the statin simvastatin (Zocor) each day.

In those not taking statins, fitness increased by an average of 10 per cent of the 12-week study. However, in those taking simvastatin, fitness increased by only 1.5 per cent on average.
