Speed is Newtonian. That is, it follows Newton's third law of motion; for every action there is an equal and opposite reaction. Speed is the result of of ground contact force (GCF) and ground contact time (GCT). How these two forces work together is the new formula for speed.
When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body. -Newton's Third Law of Motion
I've spent a lot of time doing different barbell complexes this summer. Given my garage gym, complexes are a great option. I've experimented with 3 basic types of complexes…
