The Diet and Fitness Roadshow came to Northampton and gave women a chance to hear talks about diet and fitness, as well as work out with Rosemary.

The 40-minute session saw Rosemary lead the 225 participants in a workout to a variety of songs, including Living La Vida Loca by Ricky Martin.

She said: "This is a motivational day for members of our classes and readers of our magazine. We are educating them about having a healthy diet and doing fitness. It's lovely to see all these people here, it's very exciting and wonderfully positive. It's a very fun day."

Participants at the roadshow came from Oxfordshire, London and Nottinghamshire, as well as Northampton.

Ms Conley said: "I know they get a lot from it. At classes, when they've done a roadshow they all lose weight.

"Exercise is absolutely crucial if you want to have a toned-up body at the end of your diet and it will complement weight loss."

Chris Powley, aged 45, a leather technician from Moulton, said: "There is diabetes in my family, I'm one of four girls and it looks like we're all heading the same way, so I decided to come - my sister had come for nine years.

"Today has been really good, they've really got everybody going and you see it's about being healthy."

She had bought her friend Yvonne Hawgood a pass to the roadshow for Christmas. Yvonne, aged 56, an administrator from Duston, said: "The talks were good and they didn't make us feel guilty. It's given us quite a strong message. The workout was really good."
