In this episode, Coach JK simplifies one of the most misunderstood areas of fitness: cardio. From walking to sprinting, not all cardio is created equal; and most people aren’t as clear as they think about what kind they’re actually doing.

You’ll hear Coach JK break down what cardio actually is, how to tell the difference between low, moderate, and high intensity using the talk test and RPE scale, and why Sprint Interval Training (SIT) became a necessary term after high-intensity interval training (HIIT) got watered down.

He also unpacks two key reasons people turn to cardio (fat loss and heart health) and explains why understanding the difference between burning dietary fat and body fat matters more than you think.
