The debate between High-Intensity Interval Training (HIIT) and Low-Intensity Steady State (LISS) cardio is endless. The truth is, they both have a place in a well-rounded fitness regimen, but they serve different purposes.

HIIT: The Time Saver

HIIT involves short bursts of maximum effort followed by brief rest. It burns a high number of calories in a short time and elevates your metabolic rate for hours post-workout (EPOC). However, it is highly taxing on the central nervous system.

LISS: The Recovery Tool

LISS involves maintaining a steady heart rate (like brisk walking or light cycling) for 45-60 minutes. It burns primarily fat for fuel during the session and is fantastic for active recovery, joint health, and cardiovascular endurance without impeding muscle recovery.

The Verdict: Mix them. Do 1-2 HIIT sessions a week for metabolic conditioning, and use LISS to boost your daily step count and aid recovery.
