Strength training programs vary in frequency, intensity, and volume (Vaughn & Micheli, 2008). There has been extensive debate over the optimal number of repetitions or sets required to improve muscular strength. Some believe that multiple sets are necessary to realize optimal results (Kramer et al., 1997; & Rhea et al., 2002; Schlumberger et al., 2001). Others contend that a single set per training session is all that is required and that it is no more beneficial to complete successive sets (Carpinelli & Otto, 1998; Carpinelli et al., 2002; Otto & Carpinelli, 2006).
