Kiri was a
child prodigy and started lifting weights at the age of seven. At 19 years old in 1983, Kiri held a World Record in powerlifting in the
squat in
IPF competition, with a lift of in 125 kg weight category. In one of his first ever strongman competitions in 1985, he defeated the reigning World's Strongest Man
Jón Páll Sigmarsson. The 1.94 m (6 ft 4 in), prime Kiri is particularly noted for his static strength including a single-arm
deadlift and a raw
bench press. He squatted in the Dutch Open strongman contest of 1995 in a Smith machine apparatus. He also bench pressed raw in an official WPC meet along with many other records. For most of his appearances in
World's Strongest Man competition, Kiri was hampered by
ankle injuries. Although Kiri placed 3rd and 2nd respectively in
1993 and
1996, ankle injuries plagued him during both contests. In reference to the Car Carry event in 1993, Kiri's coach, Markku Suonenvirta, famously said: "His ankle is broken but he's a tough guy." Kiri's ankle was in fact not broken but badly injured and weakened. In the 1996 WSM final event (Power Stairs) Kiri was about to go head to head with
Magnus Ver Magnusson. However, just after the starter's whistle, Kiri dropped out due to another ankle injury. Kiri was also forced to drop out of the
1998 World's Strongest Man final due to an ankle injury, finishing in 6th place. His background is in security work, and he holds shares in
Gold's Gym-Helsinki. ==Personal records==
