Fitness is a multifaceted concept that can be difficult to define because it means different things to different people. However, there are some common themes that emerge from our discussions on the show. Fitness can be seen as a spectrum, ranging from pursuing extreme physical skills or sports performance to focusing on overall wellness and longevity. It encompasses the ability to be resilient, overcome obstacles, and thrive in our environment. While aesthetics often play a role in how we perceive fitness, it's important to remember that looking a certain way doesn't necessarily equate to being fit. Ultimately, how you define fitness should be based on your own goals, abilities, and circumstances. It's not a static target and should be redefined as your life changes. Whether it's being able to run a marathon, lift heavy weights, or simply have the energy to take care of yourself and your loved ones, your definition of fitness should align with what truly matters to you.
