Proper Technique:
A-skips are essentially a regular skip with form enhancements to promote proper body mechanics in running form
In the upper body, the torso is maintained in an erect position while the arms are swung deliberately tight to the sides with a 90* bend
Hands are swung through a range of motion that permits the hands to align with the cheekbones of the face in front of the torso and the gluteals behind the torso
This is sometimes referred to as “cheek to cheek” arm form in sprinting
In the lower body; the forward knee is deliberately brought high to waist level and the toes are cocked up by dorsi-flexion (toes facing ground, heel is up) of the ankle
Make sure that the opposite arm and leg are propelled forward simultaneously just like during a sprint
Movement occurs in the sagittal plane
