To use these hurdles, simply place them on a flat and even surface like a track or a sports field. Arrange them at appropriate intervals based on your training needs. When you're running through them, try to step over each hurdle quickly and lightly to improve your footwork and agility. As for maintenance, after each use, make sure to clean off any dirt or debris. Store them in a dry place to prevent damage. Be careful not to place heavy objects on them as it might deform the innovative back - bounce construction. With proper use and care, these hurdles will serve you well for a long time.
