BIGGEST Loser fitness guru Richard Callender was in Sawtry on Sunday to put weight-watchers through their paces.

The celebrity personal trainer ran three classes, Armageddon Circuits, Urban Funk and Total Body Workout, in an effort to raise the profile of exercise as part of a healthy lifestyle.

More than 150 people attended the event at Sawtry Leisure Centre, which was co-ordinated by Sawtry WeightWatchers leader Liz Stannard.

"The objective of the day was to encourage people to try something new and let them see what they could achieve in a fun environment.

"May is also Weight Watchers Move More month, so it tied in nicely."
