The recommendation of three to four sets for each training exercise in strength training is supported by research indicating that this range is often optimal for promoting strength gains and muscle hypertrophy. When performing three to four sets, individuals typically engage in a volume of training that is sufficient to stimulate the muscles effectively while also allowing enough recovery time between sets. This balance helps to create a challenging environment that fosters progress without leading to increased risk of overtraining or injury.

Training with too few sets, such as one to two, may not provide enough stimulus for significant adaptations, especially for those beyond the beginner stage. Conversely, performing five to seven sets or more can result in diminishing returns due to fatigue and insufficient recovery, which may hinder performance and overall effectiveness of the workout. Therefore, the recommendation of three to four sets strikes an ideal balance for most individuals looking to enhance their strength training outcomes.
