Lower resting heart rate reflects a more efficient cardiovascular system from conditioning. When you train regularly, your heart becomes stronger and can pump more blood with each beat (greater stroke volume), so it doesn’t need to beat as often to deliver the same amount of blood at rest. On the SWF continuum, Fitness is associated with this lower resting rate, and 50 bpm fits that well-conditioned range. A resting rate around 70 or 60 can be healthy but isn’t as indicative of high aerobic fitness, while a resting rate over 100 bpm is not normal at rest and suggests poor conditioning or a stress response. So, 50 bpm best signals Fitness on the continuum.
