Top trainer urges everyday step count over complex fitness metrics

Celebrity trainer Harley Pasternak says most people should ignore Zone 2 and VO2 max and instead track daily steps for health.

Harley Pasternak, a well-known personal trainer with celebrity clientele, told one outlet that terms like Zone 2 and VO2 max are largely irrelevant for the average health-conscious individual. Citing his academic background from the University of Toronto, he explained that his own priorities are pain-free mornings, overall fitness, longevity, and playing with his children, not precise oxygen-use measurements. Pasternak believes daily step count offers a straightforward, actionable metric for most people, allowing gradual improvement.

He warned that many users of devices such as Oura rings or WHOOP straps become enamored with data they don’t understand. His perspective aligns with Dr. Suzanne O’Sullivan, who also favors step tracking over more technical measures. Both suggest focusing on consistent movement rather than chasing specific heart-rate zones.

Why it matters

It reminds readers that simple activity goals can be more effective than complex fitness data.
