What Is LISS? Understanding Low-Intensity Steady-State Cardio

What Is LISS?

LISS (Low-Intensity Steady-State) is a form of cardiovascular exercise performed at a low intensity for a continuous, steady duration.

In simple terms, LISS means moving at a comfortable pace—such as walking or light cycling—for an extended period without pushing your limits or spiking your heart rate.

LISS is widely used for fat loss support, recovery, endurance building, and general health, making it suitable for beginners, active recovery days, and long-term sustainability.

Purpose of LISS Training

LISS is designed to:

Improve cardiovascular health gently
Support fat burning at lower intensities
Enhance recovery between intense workouts
Reduce stress on joints and muscles
Increase daily activity levels
Improve metabolic flexibility
Support long-term fitness adherence

LISS focuses on consistency and sustainability, not maximum intensity.

How LISS Works

1. Low Heart Rate Zone

Exercise is performed at approximately 50–65% of maximum heart rate.

2. Continuous Movement

Activity remains steady without intervals or sudden intensity changes.

3. Fat Oxidation

The body relies more on fat as a fuel source at lower intensities.

4. Minimal Recovery Cost

Low stress allows frequent sessions without overtraining.

Common LISS Exercise Types

Frequently Asked Questions (FAQ)

What is LISS in simple terms?
LISS is low-intensity cardio done at a steady pace for a long time.

Is LISS good for fat loss?
Yes, especially for sustainable and long-term fat loss.

How long should LISS sessions be?
Typically 30–90 minutes.

Can beginners do LISS daily?
Yes, if intensity remains low.

Is LISS better than HIIT?
Neither is better; they serve different goals.

Conclusion

LISS is a simple, effective, and sustainable approach to cardiovascular fitness and fat management.

By keeping intensity low and movement consistent, LISS supports heart health, recovery, and long-term adherence to an active lifestyle.

In a fitness world dominated by high intensity, LISS remains an essential and often underestimated tool for balanced health and performance.
