Why the A-Skip Progression Should be a Pillar of Your Speed Program (Pt 1)
/The A-skip progression (ASP) is a tool that helps to develop proper sprinting posture, quality joint stiffness, and joint kinematics required for high level sprinting. Athletes of every level are taught the progression, and depending on their level of development, it is either used as a warm up tool, or a teaching tool. This is an extremely valuable drill for performance coaches. This drill has a high return on investment, and multiple skill levels of athletes can work simultaneously, while being on their own progression level. This makes the ASP a staple of our speed program.
It does not take a genius to recognize that if we struggle with an activity at half speed, there is a small chance that we will be able to perform the same activity at full speed with any level of coordination. In performance training, we take the same approach to teaching new drills to our athletes. We move from slow controlled movements, with long isometrics in key positions before advancing to dynamic movements that require a high level of coordination. The ASP is no different
In the very beginning, we start with an in-place iso A-March. This level requires the athlete to get into a “90/90” position which means 90° of hip and knee flexion. The down leg is straight, and if we are cueing arm mechanics as well, the opposite shoulder of the down leg is extended with the same side shoulder flexed. This level allows a coach to correct form while simultaneously giving the athlete time in the new position. If an athlete is struggling to stay balanced, and shows no sign of improvement, do not rush to progress. Give them more time in the position and combine some corrective exercises that target the same working muscle groups/movements to help hammer home the drill.
After mastery of the in-place iso A-March, we can now begin to move forward. A-March w/ pause now requires the athlete to repeat the same movement for a predetermined distance. I suggest giving the athlete a few steps in between each rep to give them time to think about the movement. If the athlete demonstrates movement competence, we can advance the movement by having the athlete perform the A-March on every step. Either way, there is a brief pause at the top of the movement that clearly separates the up from the down. Another key variable is making sure the athlete strikes the ground directly under their center of mass. High level sprinting requires proper ground contact, and to help ensure this, we ask our athletes to do the same at walking speed.
The third progression of the ASP is coined Suave A-March. The only difference being there is no pause at the top of the movement. The athlete must perform the A-March in a successive movement rhythm while maintaining quality technique. Again, start by giving the athlete a few steps in between each repetition. As they show progress we can then advance to “every step is a rep.”
We will continue the ASP next week. Just like our athletes, we have to take new information one step at a time ;) ! Once we cover the ASP in totality, we can then discuss why, when, how, etc. Stay tuned!
Thank you for your time!
