The 1970s were the most successful in the club's long history. During that time Resovia led by Jan Strzelczyk and Władyslaw Pałaszewski achieved its biggest successes, winning four Polish Championships (1971, 1972, 1974, 1975), one Polish Cup (1975), and a silver medal of the 1972–73 CEV European Champions Cup. The team of that time consisted of such players like Bronisław Bebel, Stanisław Gościniak, Marek Karbarz or Włodzimierz Stefański who played a major role in the Polish national volleyball team, leading Poland to the titles of 1976 Olympic Champions and 1974 World Champions. In the next years, the club also managed to win 2 Polish Cups in 1983 and 1987 before being relegated in 1991.
