Set up a clear patch
Move away from rugs, low furniture and anything overhead. Wear supportive footwear if the floor is hard or slippery, and keep water or hot surfaces out of reach.
Begin with a march
Stand tall, lift one knee at a time and let the opposite arm swing. Build the pace gradually. Staying light on your feet matters more than lifting your knees high.
Choose your impact
Keep one foot on the floor for a brisk march, or move into an easy jog if that feels comfortable. You can alternate 20 seconds quicker with 20 seconds easy without ever sprinting.
Stop on warning signs
Stop if you feel pain, dizziness, chest discomfort or unusual shortness of breath. If a condition affects exercise, ask a clinician what is appropriate for you.
