  • Everyone knows exercise is good for you, but many of us don't do enough.

  • Dr. Michael Roizen, a longevity expert, shared how he fits exercise into his busy schedule.

  • He has a walking desk to help him hit 10,000 steps a day and parks his car a mile from work.

A busy doctor and longevity expert who says he's reversed his age by 20 years shared with Business Insider how he finds time to stay fit.

Dr. Michael Roizen, 78, the chief wellness officer at Cleveland Clinic and author of books on longevity, says his "biological age" (a concept on which researchers are divided) is 57.6.

Regular exercise is a key part of his health routine. Although he doesn't work out enough to achieve maximum strength or fitness, he says, he walks whenever he can and squeezes in a few dedicated exercise sessions each week.

Research suggests that even small amounts of exercise and lower-intensity workouts can help keep us healthy.

That may be welcome news to the vast majority of Americans who, according to the National Center for Health Statistics, don't do the minimum 150 minutes of moderate-intensity exercise each week recommended by the government. Evidence suggests a lack of time is one of the biggest factors that stand in people's way.

Here's Roizen's weekly exercise regime.

Cardio three times a week

Three times a week, without fail, Roizen does 48 minutes of cardio, or aerobic, exercise on a treadmill or exercise bike. He chose that number because that's how long he used to play squash for, and he wants to be fit enough to play again.

He does this on Wednesday evenings, Saturdays, and Sundays. If he knows he'll have to miss a session because of a social event, he makes up for it another day.

Cardio exercise has a huge range of health benefits, including strengthening the heart, improving mood, and reducing the risk of heart disease, high blood pressure, and type 2 diabetes, according to the Mayo Clinic.

10,000 steps a day

Roizen walks as much as possible, aiming for 10,000 steps a day. To keep moving throughout the day, he uses a treadmill desk when working in his office and walks patients in and out of his clinic.

He also parks his car a mile away from work, helping him to rack up 2,000 steps in his commute. If he hasn't met his target by the end of the day, he'll get on a treadmill or exercise bike.

The popularly quoted goal of 10,000 steps a day has its origins in marketing for a Japanese pedometer company, but walking has many health benefits. In a 2022 study published in the journal GeroScience, 30 minutes of brisk walking five days a week appeared to lower the risk of cardiovascular disease and type 2 diabetes, improve mental well-being, and increase longevity.

Even if you can't reach 10,000 steps a day, a study found that walking an extra 500 steps a day could improve your longevity.

Weight lifting twice a week

After two of his three weekly cardio workouts, Roizen lifts weights.

He says resistance training is great for building muscle and improving longevity.

One 2022 study published in the British Journal of Sports Medicine linked doing 30 to 60 minutes of resistance training each week with a 17% lower risk of dying from any cause, an 18% reduction in the risk of cardiovascular events, and a 9% lower risk of developing cancer. Similarly, a 2019 meta-analysis published in the European Journal of Preventive Cardiology suggested one or two weekly resistance-training sessions could lower a person's risk of dying from any cause.
