 In another randomized study, scientists divided 24 sedentary adults, ages 18–40, into an exercise group and a control group.The exercise group added 7 abdominal exercises, 2 sets of 10 reps each, 5 days a week, for 6 weeks, into their daily routines.The scientists discovered that at the end of the 6 weeks, through comparing a variety of endurance tests, body composition tests, and anthropometrics, the subcutaneous fat around the abdominal region did not shrink.
