In addition to his four World's Strongest Man titles, he was also runner-up in 1992 and 1993. He has also won the Iceland's strongest man competition many times and the West coast Viking (Vestfjarðavíkingurinn) of Iceland nine times, he is considered to be one of the first modern strongman competitors, and is regarded by many to be one of the best strongmen of all time. He carried Jón Páll's formula of being athletic for the dynamic tests of strength and having tremendous static strength to out lift some of the best Powerlifters. He was able to easily out deadlift the favoured Wilson by 40 kg in 1991 and out squatted the world record holder in the squat, Gerrit Badenhorst , in 1995. After Magnus squatted kg, Badenhorst commented that he had previously underestimated Magnus' pure strength and that Magnus' squat was the greatest squat he had ever seen from someone of his bodyweight.
