Taking an hourly break from reading a book to walk around or listening to audiobooks while walking can provide the health benefits of book reading without incurring the health risks of prolonged sitting.

In a large United Kingdom study, regularly practicing racket sports, swimming, or aerobics significantly reduced the risk of dying over eight to 13 years.

Perhaps the best-known problem with fitness trackers is that people often retire them to a junk drawer after a few months, once the novelty of using them wears off. But that's not the only shortcoming with these devices, which are typically worn around the wrist or clipped to clothing.

Sure, they'll count your steps, display your heart rate, and even estimate how many calories you've burned—although you'll probably need to sync your tracker with an app on your smartphone, tablet, or computer to see these data. However, very few of the popular free apps of this type are grounded in published evidence. And they don't necessarily follow well-established exercise guidelines. Even if you do meet recommended daily exercise goals—like 30 minutes of brisk walking or 10,000 steps—how do you know if you're really working your heart enough to keep it healthy? And what if you've been sedentary for years or have a chronic medical condition—can an app help you exercise safely?

People who bike to work or cycle for pleasure may have a slightly lower risk of heart disease compared with noncyclists. 

If you are ready to make a commitment to improve your fitness and health, joining a gym gives you a wide variety of options for equipment and types of workouts. This can help you sidestep workout boredom and help you meet recommended physical activity guidelines. But before you sign up, take time to ask questions to be sure the gym meets your needs and budget.

One of the hottest trends among the workout set springs from your old stationary bicycle. The new use for old wheels is a supercharged cardio workout called indoor cycling or Spinning (its trademarked name). First popular in the 1990s, the activity is still going strong and is now popular among older adults. "Many classes are specifically for seniors, with instructors who are familiar with modifications for your age group," says Jacob Girlinghouse, a physical therapist with Harvard-affiliated Brigham and Women's Hospital.

The workout and benefits

Making it work

It appears that adopting a regular routine of moderate physical activity, such as walking, helps older adults remain mobile longer and may also help them to recover faster from physical disabilities. 

A large international study of people around the world suggests that extreme physical exertion or emotional upset may be triggers for a heart attack.

If getting in shape tops your list of New Year's resolutions, you're in good company. During the first few months of the year, sign-ups at fitness centers and health clubs tend to trend upward. While these memberships can be costly, you may be able to find more affordable options or take advantage of discounts. But no matter what you pay, shelling out a monthly fee may encourage you to use the gym regularly to get your money's worth. If you do, your heart will likely reap the rewards: regular exercise is one of the best ways to boost cardiovascular health.

"The main advantage to joining a gym is to have access to a wide variety of exercise equipment," says Alex Petruska, a senior physical therapist at the Sports Medicine Center of Harvard-affiliated Massachusetts General Hospital. That includes machines for a cardiovascular workout, such as treadmills, elliptical trainers, stationary bikes, and stair steppers, as well as a variety of weight machines.

Wristwatch-style fitness monitors use a sensor that detects blood flow through the skin to estimate a person’s heart rate. Some brands are more accurate that others, but none are as accurate as chest-strap monitors.
