Using this speed chute is simple. Just attach the adjustable band around your waist and start running. As you move, the chute will open up and create resistance, which helps to strengthen your muscles and improve your speed. When using it, make sure the band is securely fastened to avoid it coming loose during your run. Also, be careful of your surroundings, especially if you're running in an area with obstacles. For maintenance, after each use, shake off any dirt or debris from the chute. Let it dry completely if it gets wet. Store it in the included carry - bag in a cool, dry place to keep it in good condition for a long time.
