The Optimal Training Volume to Build the Most Muscle (Tons of Research!)

One of the most common questions among lifters is figuring out exactly how much volume or how many sets one should do in a workout.

On one hand, some say that doing a few sets close to failure is sufficient for muscle growth and doing too much can cause injury, overtraining, and excess fatigue. On the other, others say that the more volume, the more gains. Which is right and which is wrong?

The short answer is that there is no one-size-fits-all answer as different training frequency may work better for others. The long answer? Here we will look at some evidences to find out how many sets of workout you should do to optimally build muscle.
