BOB DOUGHTY: To get the most from your exercise plan, experts say adults should get at least two and a half hours of aerobic exercise each week. More intense activities reduce the suggested amount of time to one hour and fifteen minutes. Some examples are playing basketball, swimming and distance running.
Earlier advice from the CDC said people need to exercise thirty minutes each day for at least five days to get the health benefits of exercise. More recent research suggested that those gains are the same whether you exercise for short periods over five days or longer sessions over two or three days.
In addition, the newer suggestions say any exercise plan should include at least two days of muscle training. Each exercise period should be at least ten minutes long. The total amount of activity should be spread over at least two days throughout the week. Most importantly, experts say people should choose physical activities that they find fun. This helps to guarantee that they stay with the program.
