Today's guest, Dr. Benjamin Levine, has shown that with the right exercise protocol, people who were sedentary most of their lives could reverse up to 20 years of heart aging. Dr. Levine is one of the world's leading experts in understanding how the heart adapts under a variety of conditions, whether that's exercise, elite athleticism, or hospital bedrest. Or even highly exotic conditions, like prolonged exposure to microgravity. He is the founding director of the Institute for Exercise and Environmental Medicine at UT Southwestern in Dallas.

Mindsip insights from this episode:

Exercise four to five days weekly for heart health

Exercising two to three days a week offers no protective effect against heart aging; the minimum effective dose is four to five days per week.

Stabilize arterial plaques through extreme exercise

Extreme exercise may increase coronary calcium, but it also tends to make arterial plaques more calcified and stable, which are less likely to rupture.

Avoid reliance on consumer HRV trackers for training guidance

Consumer-grade heart rate variability (HRV) measurements are too unreliable and variable to be used as a meaningful guide for training or recovery.

Avoid intense recovery sessions to prevent overtraining

Making your recovery sessions too intense is a more potent trigger for overtraining than simply increasing your main training load.

Discover optimal exercise intensity to overcome non-responder myth

There are essentially no 'non-responders' to exercise, only individuals who have not yet found the sufficient dose or intensity required to see improvements.

Establish optimal weekly routine for a youthful heart

An optimal weekly routine consists of one long session, one high-intensity session, two to three moderate sessions, and one to two days of strength training.

Reverse heart aging by intervening in late middle age

It is possible to reverse the effects of sedentary aging on the heart, but the 'sweet spot' for this intervention is in late middle age, from 50 to 65 years old.

Avoid bedrest to maintain cardiorespiratory fitness

Three weeks of complete bedrest causes a greater decline in cardiorespiratory fitness than 30 years of normal aging.
