Muscle Failure And Training Intensity

Build Muscle With Hypertrophy Specific Training

The key to muscle growth is to push your muscles to a point where it is forces to recruit all muscles fibers, thereby shooting the intensity.

Temporary Muscle Failure

I will explain this with help of the basic barbell curls. Suppose you lift 60 pounds on this exercise for 8 reps, and when you try to push one more rep, you find that you cannot lift your arms to the fully contracted position (top of the concentric movement). This is the point of temporary muscle failure. In other words, when you cannot perform any more rep for any movement (fully contracted position), it is known as state of temporary muscle failure.

How To Build Muscle Fast: Exploring Tension & Stress

Isometric Phase

During this phase, the target muscle is stimulated. As a result, force is generated, minus joint movement.

Eccentric Phase

Negative Resistance Training involves controlled lengthening of the target muscle. When you lower the weight, the muscle lengthens to protect you from getting injured (due to sudden fall). Negative Resistance Training is the same as eccentric muscle action.
