Final answer:
For muscle hypertrophy, approximately 3 sets per exercise are generally recommended and shown to be more effective than 1 set, although actual number may vary depending on various factors.
Step-by-step explanation:
For muscle hypertrophy, multiple studies have shown that performing more than one set per exercise tends to be more effective in stimulating muscle growth. Generally, it is recommended to complete approximately 3 sets per exercise for optimal hypertrophy.
However, this can vary depending on individual training history, intensity, volume, frequency, and other factors. It is important to note that while 3 sets may be more effective than 1 set, performing excessively high numbers of sets might lead to overtraining and potentially impair muscle growth. Therefore, balance and proper programming are key when determining the appropriate number of sets for muscle hypertrophy.
