Fitness trainer to the stars Mark Anthony is planning to expand his low-cost gym concept Rush Fitness in sites across the south east of England.

Having launched the first two Rush Fitness sites – Uxbridge and Southend – in 2013, Anthony will now open a new health club in Aylesbury this August, with at least one more to follow this year in London Woolwich.

Anthony previously owned his eponymous club in Notting Hill – where he trained celebrity clients including Katie Price, Billie Piper and Lucy Mecklenburgh – before selling the site to Heartcore Fitness in July 2014 in order to focus on Rush.

The independently-owned Rush clubs are a low-cost, no-contract proposition, with a notable emphasis on group fitness. The Aylesbury gym will offer pre-opening membership from £12.99 per month, rising to £24.99 per month when the club opens.

“We believe that results driven by motivation, not a 12-month tie in, should be the catalyst for a long standing gym membership, so there will be no joining contract,” said Anthony.

“And unlike many low-cost gyms, Rush Fitness will offer a wide range of classes free to all members, including Spinning, Fast & Furious, Boot Camp, Mind & Body, Rush Hour and even Look Good Naked!”

Leisure design and build specialist Createability has started work on the Aylesbury club – a £450,000 project to develop the 1,000sq m (10,764sq ft) site in Friars Square shopping centre.

The development includes entry pods for 24-hour access, colour-led zoned areas for strength work, CV and functional training, an aerobic/spin studio and two changing rooms.

The club will feature more than 120 CV and strength stations, plus a 94sq m (1,012sq ft) functional training suite. Intenza Fitness will be the main equipment suppliers.
