How to Do the Alternating High-Knee Running

  1. Stand in a clear area with your elbows comfortably bent.
  2. Begin a controlled running rhythm in place.
  3. Lift one knee in front while the opposite arm swings forward.
  4. Return that foot toward the floor and switch to the other knee and arm.
  5. Continue at a manageable pace; pause or reduce the knee lift if the steps become uncontrolled.

Choose a manageable starting bout

Start with a short bout and controlled movement. Increase duration or repetitions gradually rather than using a universal target for every conditioning drill.

Cardio Pacing & Duration

Begin with a short bout you can complete while maintaining the demonstrated movement. Use time, distance or manageable repetitions appropriate to the activity, then build duration gradually before increasing effort.

For moderate aerobic effort, you can generally talk but not sing. Machine levels, speeds and calorie estimates are not interchangeable between people or equipment.

Read the CDC guide to measuring activity intensity.

Technique & Form Tips

The legs alternate a forward knee drive and a return toward the floor while the arms counter-swing. Knee height can be adjusted; the animation is not evidence that the knee must reach the chest.

Common Mistakes to Avoid

  • Following the old squat instructions: Match the alternating running action shown in the demonstration.
  • Forcing the knees upward: Use a height you can repeat without leaning backward.
  • Chasing maximum speed: Keep the foot contacts and arm swing controlled before increasing pace.

How to Breathe During This Exercise

Breathe steadily and choose a pace that lets you maintain the movement. Slow down or pause when technique or breathing becomes difficult to control.
