With a background in sports science, and strength & conditioning, Lewis began working as a physiotherapist in 2003 at NHS Forth Valley in Stirling. A specialist interest in football led him to work with elite youth football players at Motherwell FC and Rangers FC. Following this, he spent several years at Celtic FC where he designed and implemented the junior youth academy sports science program. In 2008 Lewis reluctantly declined the invitation to become Celtic F.C’s 1st team strength & conditioning coach, due to a desire to experience working in professional rugby. In 2009 he began working with the Scottish Rugby Union and provided physiotherapy cover for the Caledonia regional development programs until 2012. One of the highlights of his time at the SRU was being selected as the SRU’s physiotherapist for Scotland’s’ Youth Commonwealth Games 7′s team in 2011.
After a hip labral tear ended his MMA training with the Dinky Ninjas, Lewis turned to strength training, and started competing in Strongman in 2011. After doing well in several novice, and intermediate competitions Lewis finished fifth in Scotland’s Strongest Man 2013, and represented Scotland at the UK’s Strongest Man the same year. After a two year hiatus from competing again due to injury, he returned in 2016 to win the Scottish Natural Strongman title, and finish 5th at Britain’s Natural Strongest Man. Turning his hand to powerlifting in 2015, Lewis broke the Scottish BDFPA bench press record at his first attempt in the 145kg weight class, and won the Scottish Open in the 145kg class the same year. Despite qualifying for the British Championships in 2016, he sadly tore his left quadricep on his second squat of the meet, attempting a new meet PR of 272kg. Lewis recovered from this injury and went on to squat 282.5kg raw, proving that you can come back from a serious injury like that and best your old records. In 2017 he once again returned to Strongman qualifying and competing in Scotlands Strongest Man 2017.
Business partner Mark McKenzie, and Lewis formed Elite Sporting Performance LTD in 2012 with the intention of providing elite level physiotherapy services to athletes, and the general public.
