The combat-based fitness facility Gymbox has opened its third centre after securing a £2.1m funding package from private equity group Hotbed and HSBC bank.

The newest 'New York-style' health club was constructed in the old bank vault of the former Lloyds of London building on Lombard Street, East London. It will join the group's two other gyms in West London's Covent Garden and Holborn.

All the clubs feature a nightly resident DJ, over 70 pieces of equipment, a Olympic-sized boxing ring, 25 punch bags and a free weights area.

It will also continue to offer over 100 weekly classes including ultimate fighting and the ladies only workouts.

The Gymbox was originally operated by Fitness First, until it was bought out by Gymbox CEO Richard Hilton in 2005. The buy-out was funded by HSBC and Hotbed, with help from accountancy firm Baker Tilly.

There are plans to open a fourth London site later this year.
