According to Jeanette Ross, there are no age limits to faith, fellowship or fitness. In September, the Cambridge woman celebrated her 92nd birthday. She continues to lead an exercise class twice each week at the Cambridge United Methodist Church, at 120 W. Exchange Street. The group, which ranges up to eight participants, meets at 9 a.m. on Tuesdays and Thursdays in the second level fellowship hall of the church. "All ages and all denominations are welcome to join us," Ross says.
