Daniel Racoveanu(Bodybuilder) vs. Ion Oncescu(Armwrestler). Technique and overall arm strength are the two greatest contributing factors to winning an arm wrestling match. Other factors such as the length of an arm wrestler's arm, his/her muscle and arm mass/density, hand grip size, wrist endurance and flexibility, reaction time, as well as countless other traits, can add to the advantages of one arm wrestler over another. John Brzenk is regarded by many as the greatest armwrestler of all time.
