WARRENSBURG A large and comprehensive fitness center is scheduled to open during late February in the new River Street Plaza now under construction in Warrensburg. Called the River Street Athletic Club, the enterprise is designed to accommodate a wide range of fitness goals-- including weight loss, toning, aerobics and body building -- for people of all ages, Athletic Club Manager Kate Yarmowich Belden said. Featuring new fitness equipment and a variety of classes, the Athletic Club will likely attract people from all over northern Warren County, which is now lacking any such facility, she said. Fitness nowdays is so important in peoples lives, she said. Well be here to encourage healthy lifestyles. The top-of-the line fitness equipment will include strength-building machines, free weights, treadmills, elliptical trainers, and cardio machines, Kate said. The Club will have 2,500-square-feet of workout areas and separate locker rooms on the first floor, plus 1,500 square feet of studio space on the second floor. The upstairs studio will accommodate a variety of activities, including classes in yoga, pilates, and spinning; a 50-plus fitness group; and perhaps karate, she said. Classes are expected to cost $5 to $8 per session, Kate said, and yearly memberships will be $320, with shorter durations available. A target date of March 1 has been set for the Athletic Clubs grand opening. A fitness trainer may join the staff of the Club, owned by Tom Grace of Warrensburg and his brother Mark Grace of California, who are developers of River Street Plaza. The retail and office complex iis primarily housed in the historic building that was once the Warrensburg Dress Factory -- and known regionally during the last half-century as the Outlet Barn. The Plaza is situated just southwest of downtown Warrensburg, across the Rte. 418 bridge, overlooking the Schroon River. A 2002 graduate of Warrensburg Central School, Kate played on Warrensburg Centrals 2001 Varsity Field Hockey Team which won a state runner-up title. She continued to play field hockey at St. Lawrence and Oneonta, where she earned a degree in Marketing and Public Relations.
