The video shows a foundational drill for teaching athletes how to properly perform the hop phase.  This drill is still a large part of my progressive drill work, but has been downgraded from my "main drill" to one of a supportive nature instead.  In my book "Long Jump & Triple Jump: From the Ground Up" I go over my newest progression for the hop phase.  Without proper attention to this phase, the triple jump will truly never reach it's highest potential.  Check out my book today!
