This episode is brought to you by LMNT, Cozy Earth, Fatty15, and Maui Nui.

We all know muscle is important, but today’s guest takes it a step further, showing why it can truly be a life-changing, even life-saving, part of our health. He shares what his deep-dive research uncovered about the history of muscle and strength training, how our relationship with it has evolved, and what those shifts can teach us about building a stronger, more resilient population today.

Today on The Dhru Purohit Show, Dhru sits down with Michael Gross to explore the profound impact of muscle and strength training on health, longevity, and identity. They discuss the importance of muscle mass in preventing chronic diseases, the role of strength in shaping personal identity, and share inspiring stories of transformation. Michael emphasizes that it's never too late to start strength training and highlights the need for a shift in the medical community to recognize exercise as a vital component of health care.

Michael Joseph Gross began his career as a political speechwriter before moving into journalism, writing for major newspapers and magazines. As a longtime contributing editor at Vanity Fair, he covered culture, politics, religion, crime, business, technology, and national security, and appeared on programs such as CBS Mornings, Morning Joe, and NPR. He is the author of Starstruck: When A Fan Gets Close to Fame and Stronger: The Untold Story of Muscle in Our Lives, which explores the central role of muscle in human health and history.
