Two groups of people did resistance-training workouts for the better part of a year.
Researchers gave some people at-the-gym programs; others were given simple low-tech exercises they could do using household objects (like soup cans), elastic bands for resistance, and their own body weight
(think push-ups). By the end of the study, the scientists saw that a gym membership didn’t guarantee success: People in both groups
lost about the same amount of weight.
And the number of people with abnormally high blood sugar (called impaired glucose tolerance) dropped significantly in both groups.
