A personal trainer thinks that his new workout plan of lifting weights combined with the cardio might help his clients lose more body fat than the workout plan of just cardio. To test his theory, he asks locals to sign up to participate in his study. 36 men and 24 women sign up for study. The trainer as well thinks the treatment will work differently on men and women. Thus, he divides the group in men as well as women and then randomizes the two treatments in each group. The trainer measures the body fat of each member, and then measures it again after three months when the workout plan has been completed.
