MOMENTARY MUSCULAR FAILURE:
The point where your working muscle is fully fatigued to the extent that it can no longer complete another repetition. The muscles are so fatigued that you are pushing or pulling as hard as you can but unable to move the weight.
IMPORTANCE OF “2 MINUTES”
FAILURE = SUCCESS
“Your RESULTS from exercise are directly proportional to your INTENSITY OF EFFORT and have more to do with this than any other training factor…”
