Dr. Michael Roizen, the chief wellness officer, reveals how he managed to reduce his age by 20 years.

Without fail, Roizen performs 48 minutes of cardio or aerobic exercise on a treadmill or exercise bike three times a week.

Roizen aims to walk 10,000 steps every day. He even walks while escorting patients in and out of his clinic.

Walking briskly for 30 minutes, five days a week, helps reduce the risk of heart disease and type 2 diabetes, and improves mental health.

Activities like running, swimming, or cycling not only strengthens the heart and lungs but also help reduce body fat.

Lifting weights or performing bodyweight exercises increases muscle strength and improves bone health.

Practices like yoga or stretching keep the body flexible and relaxed, improve overall health, and help prevent injuries.
