A study published in the Journal of Strength and Conditioning Research looked at the calorie-burning effects of a 50-minute Body Pump workout. Subjects burned, on average, 265 calories during the workout. The men burned a little more calories (315) compared to the women (214). On average, the subjects burned 5.3 calories per minute. A second trial, this time commissioned (i.e. paid for) by the Les Mills Group (the people who invented Body Pump), compared a Body Pump session lasting 57 minutes with 60 minutes of continuous cycling.
