Matt BLOXHAM is still the national U18 and U20 record holder with throws of 79,74m (5kg 2013) and 73,41m (6kg 2015). Unfortunately , for diverse reasons , he could not continue a career as senior athlete . But at the time he was certainly a world class young thrower. The document made by his coach D.POPPE during a biomechanical training session is a 4 pages commented PDF of the different phases of the throw , also with comparisons at key moments of the different turns (High point , low point , catch etc…) . Bloxham’s technique was certainly excellent with a great posture maintained all during the throw and great ”relationship” with the hammer.
