Exercise & Fitness

Exercising regularly, every day if possible, is the single most important thing you can do for your health. In the short term, exercise helps to control appetite, boost mood, and improve sleep. In the long term, it reduces the risk of heart disease, stroke, diabetes, dementia, depression, and many cancers. The Centers for Disease Control and Prevention recommend the following:

For adults of all ages

  • At least 150 minutes of moderate aerobic exercise like brisk walking or 75 minutes of rigorous exercise like running (or an equivalent mix of both) every week.  It’s fine to break up exercise into smaller sessions as long as each one lasts at least 10 minutes.
  • Strength-training that works all major muscle groups—legs, hips, back, abdomen, chest, shoulders, and arms—at least two days a week.  Strength training may involve lifting weights, using resistance bands, or exercises like push-ups and sit-ups, in which your body weight furnishes the resistance.

For pregnant women

The guidelines for aerobic exercise are considered safe for most pregnant women. The CDC makes no recommendation for strength training. It’s a good idea to review your exercise plan with your doctor.

For children

At least 60 minutes of physical activity a day, most of which should be devoted to aerobic exercise. Children should do vigorous exercise and strength training, such as push-ups or gymnastics, on at least three days every week.

Can stronger muscles pump up your heart health?

Just like aerobic exercise, targeted exercises to strengthen muscles throughout your body may also help stave off heart disease. Strength training helps burn calories and may help prevent harmful belly fat accumulation. Muscle tissue is more metabolically active, so it helps control blood sugar and lowers insulin resistance. That helps prevent type 2 diabetes, a major risk factor for heart disease. Strength training can be done with resistance bands, small hand weights, or weight machines. More »

Give yourself a lift

Research shows that weight lifting is good medicine for active older adults. While there are many weight-lifting exercises, one move to include in a workout is the deadlift.

Shore up your core

Your core muscles, which are those in your torso and pelvis, help you maintain your balance, and allow you to bend, twist and reach. Strengthening them is essential, especially after age 30 when you may start to lose muscle mass.

Inflammation plays an essential role in healing and injury repair and is an integral part of the way a person’s immune system keeps the body safe and healthy. Some inflammation is good.
