Key factors for developing muscles

• high capacity muscles (the amount of work that
muscle makes a certain amount of time)
• calories
• THE amount of training
• heavier, MAS REPETICIÒNES
• recovery
• "over-spending"

Fallen muscles
To increase the size of muscle, I have to reach muscle failure?

Imagine if these same in the midst of a series. With each repetition you do, this muscle is putting more and more weak. Notes that beams the sixth repeticiòn quite difficult. The seventh repetition you is extremely hard to complete, but what you gain. Trying repetition # 8. We give these to you all. It feels as if your whole body is shaking.
After giving 100% of you, all your heart, soul and mind, muscle basically fails. You can not complete the repetition number 8. You have reached the limit of that muscle.

You have reached the point of the series called "muscle failure". Bug muscle is when you get to the point that you can not complete or a little more repetition, no matter how much you try. You have reached its limit.

So to answer the question, yes, it is extremely important each series to the point of muscle failure. The reason is that when you take the series until that point you're sure you used and worked for the largest amounts of muscle fibers in that area.

If your blank number 1, 2 or 3 repetitions of the ruling BEFORE muscle, leaving a large amount of fibers without work / training, meaning that a large portion of muscle train ran out.
