Luke later became more interested in the strength aspect of his training, entering, and winning his first contest, a local
deadlift competition in 2011 aged 27. This led to him participating in the 'Highlands Strongest Man' in 2012, held in a gym car park in
Inverness, where he again placed first. He then went on to secure 5 consecutive Scotland's Strongest Man titles from 2013 – 2017, and consistently improved his
Britain's Strongest Man (BSM) placing each year, reaching 4th by 2017. he gained invaluable experience and was starting to get noticed on the international stage. The following year (2017) he again improved on his BSM placing (4th) and at WSM he narrowly missed a place in the final, finishing 3rd in his heat behind future WSM champions
Hafthor Bjornsson and
Martins Licis. At this stage in Luke's career, although he was steadily improving his strength, it was not reflected in his contest results. In 2018, he again missed out on a World's Strongest Man Final qualification, losing out to four time WSM winner
Zydrunas Savickas and
Robert Oberst in the heats, and placing a disappointing 6th at BSM. Luke's job, where he would work offshore for two to three weeks at a time on oil rigs without access to the suitable strongman training equipment, was seen to be hampering his preparation for competition. However with training and competition hampered by the
COVID-19 outbreak, Luke was unable to enter Europe's Strongest Man, and failed to qualify from his heat at the WSM finals. That same year however, Luke established a British record in the log press, completing a lift at World Ultimate Strongman's "Feats of Strength" showcase. In WSM he was close to a podium position, however the extreme heat and the wrong tacky selection in the final event led to him slipping from 3rd to 7th, repeating his 2019 result, whilst brother Tom lifted the winner's trophy. In 2022 Luke gained a podium finish at the Arnold Classic in Ohio in March, taking 3rd place behind
Martin Licis and
Oleksii Novikov. Luke narrowly missed out on retaining his Europe's Strongest Man crown, finishing a credible second to Ukrainian WSM 2020 winner, Oleksii Novikov. At Worlds Strongest Man 2022, held in
Sacramento, California, Luke won his heat by a considerable margin allowing him to qualify for the final with an event to spare. In the final itself, Luke repeated his Finals success of the previous two appearances, finishing 7th in a line up that contained four previous winners. The competition was won by Tom for the second year in a row. After some time away from competing in the later half of 2023, Stoltman returned to compete at the 2023 Arnold Strongman Classic, where he placed 9th. This was followed by an 8th place finish at WSM and the Rogue Invitational. Luke started working with a new coach late 2023, which saw an early improvement with a 3rd place finish at the 2024 Britain's Strongest Man final, followed by winning Europe's Strongest Man for the second time. Stoltman qualified again for the World's Strongest Man Final in May 2024, where ultimately he placed 9th, the competition was won by his younger brother
Tom Stoltman for a third time. A bicep injury sustained at the WSM final kept Luke out of competition for several months, returning strongly with a 5th place position at the US Strongman Championship, 4th place at World Tour Finals, and notably a 5th place finish at the Rogue Invitational, where he was only beaten by the podium finishers of the 2024 WSM final plus 2018 WSM winner,
Hafþór Júlíus Björnsson. Luke started the 2025 strongman season with a win at what was his twelfth year entering
Britain's Strongest Man. == Family and personal life ==
