Zone 2 cardio training, specifically steady-state running, improves aerobic fitness by maintaining a conversational pace that allows for extended duration and social interaction, according to endurance athlete and Peloton instructor Susie Chan. This approach focuses on aerobic capacity rather than peak speed, making daily physical tasks feel easier for runners of all ages and abilities.
Why is steady-state running becoming a primary fitness trend?
The shift toward steady-state running stems from a move away from high-intensity burnout. Susie Chan, a NASM certified personal trainer, identifies the “steady state space” as a tool for sustainability. Unlike track workouts where runners push for maximum speed, steady-state runs prioritize a pace where the athlete can speak in complete sentences without gasping for air.

This method aligns with Zone 2 training, which targets the lower end of the aerobic spectrum. By keeping the heart rate stable, runners build a foundation that supports longer distances and faster recovery. Chan notes that this foundation is essential regardless of whether a person is training for a 5K or a record-breaking feat.
How does the social element impact athletic longevity?
Social connectivity acts as a psychological buffer against the mental strain of endurance training. Chan describes running with others as a “nice distraction” that prevents athletes from getting stuck in their own heads. This community aspect transforms a grueling workout into a manageable social event.

Chan implements this by meeting friends on the Hampshire trails most Sundays. For those starting out, she suggests joining local social run clubs or walking groups to “take the edge off” the physical exertion. This transition from solitary exercise to community-based movement is a key trend in maintaining long-term consistency.
What are the benefits of Zone 2 training for beginners?
Zone 2 cardio makes the transition into running accessible for people who may feel intimidated by traditional “hard” workouts. Because it is not “so hard that you’re dreading them,” the barrier to entry is lowered. This is particularly relevant for those starting later in life; Chan herself did not begin running until age 35.

The physiological benefit is a more efficient aerobic system. According to Chan, this specific type of training makes everyday tasks feel easier, providing a functional fitness boost that extends beyond the running trail.
How to implement a steady-state plan into a weekly routine?
Consistency matters more than distance. The goal is to remain in the conversational zone for as long as possible, whether that involves running or walking. Integrating this into a schedule can be as simple as a weekly group meet-up.
For those looking to scale their fitness, the progression looks like this:
- Identify a partner: Find a colleague or friend to maintain the social pace.
- Prioritize the pace: Focus on the ability to speak rather than the miles per hour.
- Schedule a “Long Slow Day”: Dedicate one day a week, such as Sunday, to a low-intensity trail or road session.
Frequently Asked Questions
What is a steady-state run?
It is a run performed at a constant, moderate pace where the heart rate remains stable and the runner can maintain a conversation.
Do I have to run fast to improve my fitness?
No. According to Susie Chan, steady-state runs build the aerobic foundation necessary for long-term fitness and make everyday activities easier.
Can walking be considered steady-state training?
Yes. Chan suggests that the key is sticking to a conversational pace, whether you are running or walking.
