The joy of running fast lies not only in the thrill of speed, but in the freedom found when leaving everything else behind.

1. The added resistance forces your muscles to work harder, enhancing muscular strength and power. It particularly targets the muscles involved in sprinting and accelerations, helping you develop explosive speed.

2. The resistance provides feedback and encourages proper running mechanics. It promotes stronger stride turnover, emphasizes good form, and reinforces a more efficient running technique.
