Low-Intensity Steady-State Cardio

Meaning

A form of aerobic exercise characterized by a sustained, continuous effort at a relatively low heart rate, typically maintained at 50% to 65% of the individual’s maximum heart rate, over an extended duration. This exercise modality is clinically significant for hormonal health as it preferentially promotes fat oxidation, enhances mitochondrial biogenesis, and minimizes the acute stress response associated with high-intensity training. It is a highly effective strategy for improving metabolic flexibility and reducing ectopic fat accumulation without significantly elevating cortisol or sympathetic nervous system activity. This gentle yet sustained effort is key to building a robust metabolic foundation.
