  "account": "Celebrity personal trainer Harley Pasternak, who has worked with clients like Rihanna, is advising that health-conscious individuals should focus on a simple metric rather than complex terms like Zone 2 and VO2 max. These metrics, which indicate endurance and measure the body's oxygen usage during intense exercise, are primarily relevant to elite athletes or those recovering from heart issues. Pasternak contends that daily step count is a more accessible and beneficial metric for most people, as it quantifies daily movement. He believes that regular exercise leading to gradual fitness improvements is all that most individuals need. Pasternak's advice aligns with the findings that engaging in 150 minutes of moderate or 75 minutes of vigorous physical activity per week can lower the risk of various chronic diseases.",
