The Fitness Industry Association will kick-start its Commit To Get Fit 2002 publicity programme with an email based viral marketing campaign.

It will allow participating sites to email members, potential customers and corporate clients with a personalised message urging them to take part.

'Emails spread like wildfire, and this will provide us with a nationwide communications network,' said campaign manager Caroline Richings.

Last year, 538 clubs participated, some substantially increasing revenue by generating more than 10,000 new members.
