In addition to qualifying for the U.S. World Team and the U.S. Pan American Games team, champions from this weekend's Senior World Team Trials in Indianapolis, Ind. will receive another exciting new reward.     World Team Trials champions will receive a free one-year all-club membership to a 24-Hour Fitness Center. This added incentive has been provided by 24-Hour Fitness TeamSports, a corporate partner of USA Wrestling.    The Senior World Team Trials will be hosted at the Indiana Convention Center in Indianapolis, Ind., June 20-22.  The nation's best men's freestyle, women's freestyle and men's Greco-Roman wrestlers will compete. A total of 21 individual champions will be crowned at the World Team Trials, seven in each style.    "24-Hour Fitness TeamSports wanted to reaffirm its dedication to USA Wrestling and the Olympic Movement by supporting the elite wrestlers in their pursuit of World Gold," said Chris Feder, Vice-President of Team Sports and Sports Medicine for 24-Hour Fitness TeamSports.    Certificates for the one-year membership will be presented the champion wrestlers during the post-championship celebration on Sunday, June 22.    24-Hour Fitness and 24-Hour TeamSports are the official sponsor of USA Wrestling in the "Fitness Center" category.  In April, 2002, 24 Hour Fitness TeamSports renewed their partnership with USA Wrestling through 2004.
