Health club operator Fitness First has secured an agreement with BBC Worldwide, the UK broadcaster's commercial division, to offer new exercise classes based on Strictly Come Dancing.

The group classes are designed to encourage participants to improve their fitness levels through a range of dance moves and disciplines, including the cha cha cha, the waltz, the quickstep and the jive. Strictly Fit classes are free for members of Fitness First health clubs, although non-members will be given the opportunity to sign up to the classes with a five-day pass costing £25 for a limited period.

Fitness First's UK national fitness manager, Derek Crawford, said: "The nation is already gripped by Strictly Come Dancing and now everyone can get involved - and get fit at the same time." The health club operator is one of the largest privately-owned in the world, with more than 425,000 members at 164 sites across the UK.
