As part of National Fitness Day, fitness model Louise Glover is holding an impromptu fitness class at Tower Bridge in London at 1.00pm. Sky Sports will be there filming the event live.

If you're in the area today – you're invited to go along and take part.

Louise and a team of fitness instructors from Fit4less will descend on lunchtime city workers, getting them to take part, as well as encouraging members of the public to come down to the session.

Jan Spaticchia, CEO of the énergie Group, which founded National Fitness Day, appeared on Sky Sports News earlier today to promote the event.

Now in its third year and backed by partners Change4Life, ukactive, the énergie Group and Sanofi Inspires, National Fitness Day UK aims to become the biggest nationally celebrated fitness-focussed day of the year.
