I agree and disagree with your comment below.. I think you're 100% correct if assuming failure means doing 4 sets of an exercise and on the 4th set or all the sets for that matter, the last few reps being with bad form, adjusting body postion to allow other unnatual movements to assist witheh push/pull....
To me going to failure is so misunderstood... In order for a muscle to be properly stimulated, it has to have stress put on it.. and damage has to occure in order for growth to take place..
IMO--- if you're working out and not going to failure your going to stagnate... and maintain... but again, going to failure means... pushing the weight until you're unable to do another rep with good form.. that's failure..
What Failure Isn't: loading too much weight on a bar and barely doing 2-3 reps while contorting your body and bursting blood vessals in your head trying to push it..forced reps.. is not failure.. Forced reps should only be done periodically and only if you have hit a platue.... You should also pick your battles and not do forced reps throughout your entire routine.. only on select muscles that are lagging.. and for a short period of time..
But the problem being.. most consider forced reps.. going to failure and they're two totally different training methods.. If that's what most consider failure then you're right.. CNS will eventually set in... but not in a few weeks..
I also disagree that you have to do 3 or 4 sets in order to have mass and strength increases.. one set to warm up and one set going to failure IMO will do that same as 3 sets of managable weight and then the last set being to failure..
I hear lots of talk about CNS and due to contrary belief, it's not something that is easy to acheive.. it takes months of pushing the body with massive amounts of weight to effect the central nervous system.. often mistaken for severe soreness, pulled muscles and tendons... not CNS...
Has anyone here actually suffered from CNS Fatigue? If you have to think for longer than a second.. you probably haven't..
Most people that suffer from CNS are advanced lifters that have to push their bodies to such an extreeemee degree in order to gain strength and mass..
Not the 145 lbs 16 year old who piddles around the gym 5 days a week 2 hours a day.....doing rear laterals with 15lb DB's..
Not meaning to insult any young guys or people who do laterals with 15lbs.... Just trying to make a point...
*CNS is very misunderstood..
*Going to failure is very misunderstood...
*Forced Reps are often confused with Going to failure...
*Formed Reps should not be done with every exercise you do.. pick your battles for forced reps..

As I posted before, failure is never the target of my workout.
First of all, you can't train to failure and train frequently.
Second reason, each workout's weights should be planned and increased systematically, so there is no way you can train to failure this way since you won't be able to increase the weights each time. Eventually you will fail, but not every workout. Failure for a few weeks usually means it's time to deload.
Third reason is that failure does not occur because muscle fatigue. It occurs in the CNS level which stops so it can rest and recover. Hencs, the stress failure produces is very high, while the effect is minimal.
