Why is volume needed for strength and power?
I like 5x5 workouts. I have also done workouts involving 8 sets of 2 and 8 sets of 4, etc. But, why isn’t 1 set of 5 good enough or 2 sets of 2 instead of 2 sets of 8? What is important about volume?
Boris Sheiko has routines with huge volume.
But, then I read this online:
Many scientific studies demonstrate one set is almost effective as multiple sets, if not just as effective in strength and muscle hypertrophy (Starkey, Pollock, et. al. 1996). These studies have been criticized for using untrained subjects. Hass et. al. (2000) compared the effects of one set verses three sets in experienced recreational weightlifters.
Both groups significantly improved muscular fitness and body composition during the 13 week study. Interestingly, no significant differences were found between groups for any of the test variables, including muscular strength, muscular endurance, and body composition.
So, I was just curious why volume seems to produce the best strength and power results.
