Using a common diabetes pill while hitting the gym might actually dampen some of the benefits you get from exercise, according to a new study.

Research involving just over 800 patients has found that people who take the diabetes drug metformin while following structured exercise see measurably smaller gains in cardiovascular fitness and blood pressure than those who exercise without the drug—a finding that raises questions about whether pairing these two approaches always delivers optimal results.
