At sixty six she runs marathons works out every week swims what is her fitness secret

There is no one-size-fits-all answer to the question of what is the best fitness routine for seniors.

However, experts agree that staying physically active is important for maintaining good health as we age.

For seniors who are looking to improve their fitness, moderate-intensity aerobic exercise, such as walking, is a good place to start.

Regular aerobic exercise has been shown to improve heart health, reduce the risk of chronic diseases such as diabetes and stroke, and improve cognitive function.

In addition to aerobic exercise, seniors should also focus on strength training. Strength-training exercises help to build muscle mass, improve bone density, and reduce the risk of falls.

Finally, seniors should make sure to stay hydrated and to eat a healthy diet.

A healthy diet provides the nutrients needed for good health, and staying hydrated helps to prevent fatigue and injuries.

So what is the fitness secret of the 66-year-old marathon runner? 

There is no one secret, but rather a combination of staying active, eating right, and staying hydrated.

By following these simple tips, seniors can maintain their health and improve their fitness.
