Your cardio endurance is how effectively your heart and lungs can get oxygen to your muscles during physical activity. Many people think high-intensity interval training (HIIT) is the best way to work your cardiovascular system.
However, several forms of exercise can improve your cardio endurance more effectively than HIIT, especially if your goal is consistency and long-term heart health.
Steady-state running means running at a pace you feel comfortable maintaining for a long time without needing to stop. You should be able to comfortably hold a conversation while moving.
This type of running helps your heart pump blood and helps your muscles utilize oxygen more efficiently. If you choose to track your heart rate, you may notice over time that your heart rate stays lower even if you’re running at the same pace. This is a sign of improved endurance.
Unlike HIIT, steady-state running puts much less stress on your joints and your nervous system, making it easier to recover and train consistently.
Brisk walking is one of the most underrated ways to improve your cardio endurance. Walking at a fast pace raises your heart rate and works your heart muscle while having a low impact on your joints.
Walking is easy to recover from, which means it’s something you can do very often. Getting regular exercise helps improve the way your muscles and body utilize oxygen, also known as your aerobic capacity. This is the foundation of good cardio endurance.
Brisk walking is an especially good workout if you’re new to exercise, returning from an injury, or feel burnt out by intense workouts.
Cycling can challenge your heart and lungs without heavy impact on your joints. Cycling at a steady, moderate pace can allow you to cycle for a long period of time.
The longer you cycle, the more adaptations your body creates, improving oxygen delivery to muscles. The more you cycle, the less fatigue you will experience in your legs and the more controlled your breathing will become.
Since cycling is a low-impact form of exercise, it’s often easier to safely increase the challenge compared to high-intensity workouts.
Swimming challenges your heart, lungs, and muscles all at once. Breathing against the pressure of the water also makes your lungs work harder than if you were exercising on land.
Swimming helps keep your heart rate elevated for an extended period of time, which is key to building cardio endurance. At the same time, being in the water helps support your body, reducing overall joint stress.
Swimming is a good form of exercise if you’re looking for an intense cardiovascular exercise without high impact.
Rowing is a full-body form of exercise that combines strength and cardio. When done at a steady pace, it can improve endurance while simultaneously building muscle.
The rhythmic movement of rowing trains your body to maintain effort over time. Since it challenges both your upper and lower body, it typically raises your heart rate quickly and keeps it elevated for most of the workout.
Rowing is especially effective if you’re looking to improve endurance without sharp spikes in your heart rate, which is often seen during HIIT.
Hiking on varied terrain, such as uphill or uneven ground, can build cardio endurance by keeping your heart rate elevated for a long period.
The varied terrain can challenge both your muscles and your balance while still allowing you to move at a steady pace. This can improve stamina without overwhelming your system.
Many people also enjoy the nature views and sense of relaxation that hiking provides, making it feel less like “exercise.” This may encourage you to hike longer and stay more consistent than you would with HIIT.
Low-intensity cardio circuits combine movements like step-ups and bodyweight squats with minimal rest. The goal is continuous movement, not maximum effort.
Low-intensity cardio circuits keep your heart rate higher for a longer period, helping improve endurance. And unlike HIIT, you are not pushing yourself to the point of exhaustion.
This style of circuit training can be easier to recover from compared to HIIT, while still offering strong cardiovascular benefits.
HIIT is a great form of exercise if you’re looking to improve speed and power, but cardio endurance is built through longer, steadier efforts. These seven forms of exercise can help train your body to better use oxygen and help your heart pump blood more efficiently without requiring frequent rest.
They also allow for more frequent training sessions, which leads to better long-term consistency and results. Overall, less intense workouts are often easier to stick with and cause fewer setbacks.
The best cardio endurance exercise is one you can do consistently without feeling exhausted or bored. Choose an activity that will keep your heart rate elevated while still allowing for adequate recovery between sessions.
If your goal is improved heart health and sustainable fitness, steady and moderate exercises often deliver better results than HIIT.
