Before you start
  • Warm up first with a minute or two of easy walking or marching in place, and cool down the same way after.
  • Wear flat, closed shoes with a good grip, or go barefoot on a non-slip floor if that feels steady to you.
  • Clear the floor around you. Keep a sturdy chair, counter or wall within reach for any move you do standing.
  • Build up slowly. Add repetitions or minutes over weeks, not days. If you take a break, work back up gradually.

Talk with a doctor or physical therapist before you start if you have not been active for some time, if you have a health condition or a worry about exercise, if you have fallen or fear falling, or if a clinician has told you to limit activity. This library is general information, not medical advice.

What you need

Supportive shoes and a forgiving, non-slip surface.

How to do it

  1. Stand tall with feet hip-width apart.
  2. Drive one knee up toward the chest while pumping the opposite arm.
  3. Quickly switch legs, mirroring the arm action.
  4. Continue alternating at a fast pace.
  5. Continue for the prescribed work interval.

How much

To start: Begin with 5 to 10 minutes at an easy to moderate effort. Add a few minutes each week as it feels easy.

As it gets easier: Work toward 20 to 30 minutes at a moderate effort, building over weeks. Add intervals only after steady work feels easy.

How it should feel: Moderate effort means you are breathing harder but can still talk, and could not sing.

Tips

  • Drive the knees up to at least hip height.
  • Stay light on the balls of the feet.
  • Keep the torso upright — do not lean back.

Safety

  • Warm up first, and keep your breathing steady. Breathe out on the effort and in as you ease off. Do not hold your breath.
  • Move with control. Do not lock your joints straight at the end of a movement.
  • Choose a version, load and number of repetitions you can finish with good form. The last few should feel hard but not shaky.
  • Warm up well, and build the number of repetitions and the height slowly over weeks.
More safety notes
  • Land softly with your knees slightly bent.
  • Rest between sets. Stop as soon as your form fades or you feel tired.

From the source

  • Keep the torso upright — do not lean back.

When to stop

  • Stop and rest if you feel dizzy or lightheaded, sick to your stomach, or unusually short of breath.
  • Stop if you feel sharp, sudden or joint pain. Muscles working hard is expected. Pain is a signal to stop.
  • Stop and sit down if you feel unsteady and cannot settle yourself right away.
  • Call your local emergency number for chest pain or pressure, fainting, or sudden weakness, numbness or trouble speaking.
  • After any of these, do not repeat the exercise until you have talked with a doctor or physical therapist.
  • You feel pain in a foot, ankle, knee or hip when you land.
  • Your landing becomes heavy or uneven.
