Looking for a quick exercise that can raise your heart rate, challenge your legs, and fit into almost any workout? High knees are a simple bodyweight movement that requires no equipment and very little space.
Whether you're exercising at home, warming up before a workout, or adding intensity to a cardio circuit, high knees can be a convenient way to make your routine more dynamic.
What Are High Knees?
High knees are a dynamic cardio exercise performed by running or marching in place while lifting one knee at a time toward your chest.
The movement combines leg action, arm movement, core stability, and cardiovascular effort. You can perform it slowly as a warm-up or increase the pace for a more demanding cardio workout.
Unlike exercises that require machines or weights, high knees can be done almost anywhere.
7 Benefits of High Knees Exercise
1. Boosts Cardiovascular Fitness
One of the biggest high knees benefits is their ability to quickly elevate your heart rate.
Performing the movement continuously challenges your cardiovascular system and can help improve your ability to sustain physical activity over time.
For a more intense cardio session, increase your pace while maintaining controlled movement.
2. Helps Burn Calories
High knees can be a useful addition to workouts designed to increase energy expenditure. Because they involve several muscle groups and continuous movement, they can make a short workout feel surprisingly challenging.
However, calorie expenditure varies depending on factors such as body size, exercise intensity, duration, and fitness level.
3. Strengthens the Lower Body
High knees repeatedly engage the:
- Quadriceps
- Hamstrings
- Glutes
- Calves
- Hip flexors
They aren't a replacement for dedicated strength exercises such as squats or lunges, but they can contribute to muscular endurance when performed regularly.
4. Improves Muscular Endurance
Doing high knees for longer intervals challenges your muscles to keep working without stopping.
Over time, this can help you become more comfortable with sustained, repetitive movements—particularly when high knees are incorporated into cardio circuits or interval training.
5. Challenges Coordination and Balance
High knees require you to coordinate your legs, arms, posture, and core simultaneously.
Alternating the legs while maintaining a steady rhythm can help develop body control, coordination, and movement efficiency.
6. Engages Your Core
Although high knees are primarily associated with cardio and leg movement, your abdominal and trunk muscles also work to help stabilize your body.
Keeping your torso upright and avoiding excessive leaning can make the movement more controlled.
7. They're Convenient and Equipment-Free
Perhaps the simplest benefit is accessibility.
You don't need:
- Dumbbells
- Resistance bands
- A treadmill
- A gym membership
- Much workout space
A few feet of clear floor space may be enough to get started.
How to Do High Knees Correctly
Follow these steps:
- Stand upright with your feet about hip-width apart.
- Keep your chest lifted and shoulders relaxed.
- Engage your core gently.
- Lift your right knee toward your waist or chest.
- Lower it while driving your left knee upward.
- Continue alternating your legs.
- Move your arms naturally in opposition to your legs.
- Maintain a pace you can control safely.
Beginner tip: You don't have to jump or move quickly. Start with a controlled marching version and gradually increase your speed.
How Long Should You Do High Knees?
There isn't one perfect duration for everyone. Your workout experience and fitness level should determine the intensity.
Beginner
Try:
20 seconds high knees → 40 seconds rest
Repeat for 4–6 rounds.
Intermediate
Try:
30 seconds high knees → 30 seconds rest
Repeat for 6–10 rounds.
Advanced
Try:
40 seconds high knees → 20 seconds rest
Repeat for several rounds as part of a larger cardio or HIIT workout.
The goal isn't simply to move as fast as possible. Good technique and controlled breathing matter more than speed.
High Knees as a Warm-Up
High knees can also be incorporated into a dynamic warm-up.
For example:
- 30 seconds easy marching
- 30 seconds high knees
- 30 seconds rest
- 30 seconds jumping jacks
- 30 seconds rest
- Repeat 2–3 times
A warm-up should gradually prepare your body for more demanding activity rather than immediately pushing you to maximum intensity.
Common High Knees Mistakes to Avoid
Going Too Fast
Speed can make the exercise more difficult, but rushing may cause your technique to break down.
Leaning Too Far Back
Try to keep your torso relatively upright instead of arching your back as your knees rise.
Slamming Your Feet Down
Land softly and maintain control, especially when exercising on a hard surface.
Ignoring Your Fitness Level
You don't need to perform high-impact high knees immediately. Marching high knees are a useful lower-intensity alternative.
Skipping a Warm-Up
If you're going directly into an intense workout, spending a few minutes gradually increasing your movement can help prepare your body.
Are High Knees Good for Weight Loss?
High knees can contribute to a calorie-burning workout, but no single exercise guarantees weight loss.
Weight management depends on multiple factors, including overall dietary intake, physical activity, sleep, and individual circumstances.
Instead of relying exclusively on high knees, consider combining them with a balanced fitness routine that includes cardio, resistance training, mobility work, and adequate recovery.
Who Should Be Careful With High Knees?
High knees can be demanding because they involve repetitive impact and rapid leg movement.
If you're new to exercise, have joint discomfort, are recovering from an injury, or have a medical condition that affects your ability to exercise, consider starting with a lower-impact variation or getting advice from an appropriate healthcare or fitness professional.
Stop if you experience unusual pain, dizziness, chest discomfort, or significant shortness of breath.
