For all the health benefits of exercise for both groups, however, only 33% of women and 43% of men in the study met the standard for weekly aerobic exercise, while 20% of women and 28% of men completed a weekly strength training session.
"Even a limited amount of regular exercise can provide a major benefit, and it turns out this is especially true for women," said Cheng. "Taking some regular time out for exercise, even if it's just 20-30 minutes of vigorous exercise a few times each week, can offer a lot more gain than they may realize."
"This study emphasizes that there is no singular approach for exercise," said Eric J. Shiroma, Sc.D., a program director in the Clinical Applications and Prevention branch at the National Heart, Lung, and Blood Institute (NHLBI). "A person's physical activity needs and goals may change based on their age, health status, and schedule – but the value of any type of exercise is irrefutable."
The Physical Activity Guidelines for Americans recommend adults get at least 2.5-5 hours of moderate-intensity exercise or 1.25-2.5 hours of vigorous exercise each week, or a combination of both, and participate in two or more days a week of strength-based activities.
