The Gym Group continues to flex its muscles and cash in on the growing trend among Britons to get fitter.
The Guildford-headquartered company reported a 19.4% surge in members over the first half and now has 424,000 people on its books.
John Treharne setup the company in 2007 with backing from Bridges Ventures and the company opened the doors of its first gym in Hounslow in 2008.
The aim was to provide high quality gym-only facilities to a wide demographic through 247 opening hours, no fixed-term membership contract and an affordable monthly membership fee.
Founder and chief executive, John Treharne, said: "This is another strong performance underlining the strength of our business model, the power of our low-cost proposition and the success of our rollout."
Treharne added that the Gym Group is on track to meet full-year expectations, with analysts pencilling in pre-tax profits of up to £9m.
Last year, the firm recorded an adjusted pre-tax profit of £5.3m on sales of £60m.
The group, which listed on the stock market in November, opened six new gyms in the period, four of them within the M25.
The firm also announced a raft of board changes. David Kelly, founder of mydeco.com, has been appointed independent non-executive director and chief operating officer Jim Graham has announced that he will step down.
Former Mothercare man Nick Henwood has been drafted in to the role of operations director.
