A new study proves that the old adage “use it or lose it” is definitely true when it comes to fitness.After just two weeks of sedentary behavior, formerly fit people had:
—A decline in heart and lung health
—Increased waist circumference
—Greater body fat and liver fat
—Higher levels of insulin resistance

It’s a small study, just 28 subjects, so may not be reproducible.
