Gym-goers are helping boost the coffers of the Bradford Macmillan Appeal by taking on their instructors in a fitness challenge.

People who train at Club Indigo, including members of the Bradford Bulls Team, are signing up for the scheme which is backed by the Department of Health.

Members will donate £5 to compete head to head on the equipment to see if they can beat instructors in fitness tasks at the gym on Gallagher Leisure Park in Thornbury.

Fitness manager Lisa Salinas said the five instructors are all very competitive and gearing up for tough competition.

She said: "It is going to be fun but we are all fit enough to take on the challenge so it will be a bad show if we don't win. We are happy to be challenged on whatever the member wants."

Bulls players Brandon Costin and Lesley Vainikolo - nicknamed the Volcano - are supporting the scheme, called Commit to Get Fit Help your Body be Somebody.

Brandon said: "Any initiative which raises money for cancer charities is great. I cannot imagine how I would feel if someone in my family had cancer.

"I suppose it's two birds with one stone as well because there is a big problem in today's society with people eating fast food and not exercising. This gets people off their bottoms and away from the television."

Members will also take part in a fund-raising decathlon doing ten events within the gym and donating locker money to the appeal, which is raising £675,000 to fund specialist cancer nurses and an ethnic minorities worker.

Appeal manager Michelle Norcliffe said: "We are delighted people at Club Indigo are backing the scheme. It's up to each club what they do - and in Bradford they are really going for it."
