The Spring Ankle Series provides a systematic approach to strengthen the foot and ankle complex, optimizing power transfer and reducing energy leaks. By addressing the ankle stability and function, athletes can improve their acceleration, speed and overall performance.

The concept of the Spring Ankle was created by Chris Korfist a Track and Field/Speed coach who started Slow Guy Speed School. Cal Dietz a friend of Chris Korfist popularized the Spring Ankle Exercise in his Triphasic Training manuals and partnered with Stray Dog Strength to manufacture and distribute the product.

The Spring Ankle Series is a valuable tool for athletes at all levels, helping them develop a strong and stable foot and ankle complex. It is important to progress through the series gradually, ensuring athletes can maintain proper form and positioning before advancing to the next level. By incorporating these exercises into training programs, athletes can enhance their performance, reduce the risk of injuries, and maximize their athletic potential. Full article available on Triphasic Trainings Site
