Description

A cardio exercise where you run in place while lifting your knees as high as possible.

How to Do High Knee Run

1
Setup
Stand tall with your feet hip-width apart, gaze forward, and shoulders relaxed.
2
Setup
Engage your core, maintain a slight forward lean from your ankles, and bend your elbows at 90 degrees.
3
Explosively drive one knee towards your chest, aiming to get your thigh parallel to the ground, while simultaneously pumping the opposite arm forward.
4
Land softly on the ball of your foot, immediately switching to drive the other knee up as the first foot touches down.
5
Maintain a rapid, rhythmic pace, continuously alternating legs while keeping your core engaged and chest upright throughout the movement.

Tips

Focus on soft, quiet landings on the balls of your feet to reduce impact on your joints and maintain a consistent rhythm.
Actively pump your arms in sync with your legs; this adds momentum, increases calorie expenditure, and engages your upper body.
Aim to get your thighs parallel to the ground or higher if your flexibility allows, maximizing hip flexor and core engagement.
Breathe rhythmically and deeply, coordinating your breath with your movement to sustain effort and maintain oxygen flow.

Common Mistakes

×Slouching or rounding the back reduces core engagement and puts strain on the spine; keep your chest proud and shoulders pulled back.
×Not lifting knees high enough limits the exercise's effectiveness and hip flexor activation; actively drive your knees towards your chest with each step.
×Landing heavily on your heels can cause unnecessary joint impact; focus on light, springy landings on the balls of your feet.
