Goal is the development of max single-arm strength from a disadvantageous position.

Due to the uni-laterality of the motion there is greater need for dynamic trunk control. The athlete learns to generate a peak upper body force, while maintaining integrity of the so-called core.

In high-impact running the upper limbs help stabilizing axial congruency, they create a forceful torque for acceleration and help maintaining velocity.

As our hands are a means of communicating with ourself and our environment, certitude and confidence in our upper limb capacity can translate into other parts of our lives as well.
