It turns out exercise isn’t just good for you: it’s also good for your spouse, which is also probably good for you. Futurity reports that researchers at Johns Hopkins Bloomberg School of Public Health analyzed health and exercise data from 3,261 couples on visits that were six years apart. The envelope please…. The researchers found that when a wife met the American Heart Association’s recommended levels of exercise at the first appointment, her husband was 70 percent more likely to meet those levels six years later than those whose wives were less physically active. When a husband met recommended exercise levels, his wife was 40 percent more likely to meet the levels at the time of the followup. The American Heart Association recommends that adults exercise at moderate intensity for at least 150 minutes a week or vigorously for at least 75 minutes a week. Forty-five percent of husbands and 33 percent of wives in the study group met the recommendations at the first visit.
