One set or many? study tests best way for beginners to build muscle

This study aimed to find out if doing one set of each weightlifting exercise is as effective as doing multiple sets for building strength and muscle in men who don't normally exercise. Researchers divided 34 sedentary men into three groups: one group did single sets, another did multiple sets, and a third group didn't exercise at all. They measured changes in strength, muscle size, and physical performance over a training period to see which approach worked better.
