John Treharne, CEO of The Gym Group, commented: "We have made considerable progress in 2017 and were the fastest growing low cost fitness operator, substantially increasing our market share and rapidly expanding our estate. We continue to see potential for substantial growth in 2018 as we plan to open a further 15-20 new gyms and benefit from the profitability of those sites opened in recent years reaching maturity. We have had a strong start to 2018 and are excited about the future and confident in our team's ability to maximise our opportunity"
