How do I know if I'm doing junk volume?

In the body-building world, Junk Volume refers to any training you do that takes up time and energy but has no actual benefit in terms of muscle or strength gain.

Is junk volume good?

It not only affects your recovery but also increases the risk of overtraining, plateauing, and injuries. In other words, you might be putting in the effort, but the returns won't be as impressive as they could be. Certain muscle groups are more susceptible to the negative effects of junk volume.

Junk Volume: Why You Must Avoid It For Max Muscle

Is too much volume bad for muscle growth?

One study says higher training frequencies improve muscle growth, the next says they don't. One study suggests the optimal training volume is as high as 45 sets, the next says doing more than 10 sets is counterproductive and reduces your gains.

What is the strongest muscle by volume?

Is 9 sets a week enough to build muscle?

The most effective range for muscle growth is noted to be around 5-10 sets per week per muscle group. The minimum effective dose for hypertrophy was found to be around 4 sets per muscle group per week, which delivered detectable improvements in muscle growth.

Is 4 sets per exercise enough?

4 to 8 sets per muscle per week is now your minimum. If that's what you were doing as a beginner, you'll want to aim for 8 to 15 sets per muscle per week. At this point, your weekly volume will be much more manageable if you train three to five days a week, working each muscle at least twice.

What is hypertrophy?

WHAT IS HYPERTROPHY? Muscle hypertrophy (known simply as hypertrophy) is an increase in the size of a muscle, or its cross- sectional area attributed to an increase in the size and/ or number of myofibrils (actin and myosin) within a given muscle fiber.

What is the weakest muscle?
