The evidence that multiple sets of exercise are superior to a single set for maximal strength gains, as suggested by Berger in 1962, is reviewed. The validity and practical significance of Berger’s strength training study are questioned. Well controlled, methodologically sound studies that minimise confounding variables are required to support the hypothesis that multiple sets of exercise elicit superior gains in strength. ..........................................................................

here is a pervasive misconception that multiple sets of a strength training exercise are superior to a single set for increasing muscular size and strength. The prevalent recommendation, which appears in exercise physiology textbooks and strength training reviews, is to perform multiple sets (at least three) of each exercise. However, there is very little evidence to support the preponderant belief that multiple sets are superior to a single set. Fig 1 illustrates the labyrinth of cross referencing by physiologists who recommend the execution of multiple sets. The only evidence cited to support their multiple set training philosophy is one strength training study by Berger,1 which is perhaps the genesis of the unsubstantiated belief that multiple sets are required for optimal gains in strength. Therefore, a close examination of this study is warranted. This retrospective is based on the original information published in Berger’s study,1 as well as personal written and telephone correspondence (1998) with Dr Berger in which he clarified specific methodologies that were not elucidated in the original publication. He expressed his opinion—both before his research and currently—that multiple sets are required for maximal increases in muscular strength and hypertrophy (personal communication; 1998).

BERGER (1962) Berger1 reported that nine groups of college age men (about 20 in each group) performed strength training exercises three times a week for 12 weeks. The students (n = 177) were enrolled in one of nine weight training classes and not equated or randomised before training. There was no control group. In addition to their regular weight training programme, which is not described in the report,1 participants performed different combinations of sets and repetitions in the free weight bench press exercise—for example, three sets of six repetitions (III-6). Berger1 used roman and arabic numerals to represent sets and
repetitions respectively. All nine groups showed a significant increase (p
