The Knoxville Recreation Center is hosting their second annual holiday challenge beginning later this month. The theme of this year’s seven week challenge is “Keep it lean, win a flat screen”. The average person gains 7 pounds during the holiday season and those who participate in the challenge and are able to maintain or lose weight between November 14th and January 3rd will be entered into a drawing for a new flat screen television. The cost to participate in the challenge is $5 for members or $20 for non-members which includes 10 visits to the Recreation Center. Initial weigh-ins will be held November 11th through 13th.
