Newcastle United owner Mike Ashley is to open a chain of cut-price gyms charging £5 a month with a £10 joining fee. It is the latest expansion of his Sports Direct business after it acquired up to 30 sites from LA Fitness. The retailer claimed it would "revolutionise the market" with plans to open 200 sites charging a fraction of its rivals' prices. A flagship gym is to open at Aintree on Merseyside next month alongside a new Sports Direct store, with another to follow at Keighley, West Yorkshire. What type of integration is this?
