Whether it be CNS Fatigue or Muscular Overtraining, the problem arises due to one factor: Pushing too hard for too long without any respect for the recovery process.
Muscular overtraining occurs when you’re working any given muscle more frequently than what it’s able to handle and aren’t providing sufficient rest time between the workout sessions that you are performing.

CNS fatigue, on the other hand comes from performing general weight lifting activity too frequently. Since any time you lift a weight the nervous system is getting taxed, if you’re doing too much overall, the end result will be central nervous system overtraining.
Of the two, CNS fatigue can be way more detrimental to not only your progress, but ultimately to your health. Over train a muscle and, for the most part, you will find lack of progress being the main result (poor muscular growth and the loss of strength). Overtax the Central Nervous System and you will not only halt progress, but you will find yourself feeling overly fatigued in all aspects of your life, with a compromised immune system, a lower sex drive and a whole host of other issues.
Let’s have a look at three tips that you need to know in order to prevent CNS overtraining so you can be sure that this doesn’t become a factor in your life.
Take Complete Days Off
The very first thing that you should be doing to help prevent CNS drain is making sure that you are taking complete days off throughout the week. If you’re going to the gym each and every day, it’s not really going to matter what type of workout you’re doing. Working out 7 days a week can be a little too much for your body to handle.

Keep Your Everyday Stress Low
The second good idea to help prevent CNS overtraining is to make sure that your everyday stress levels are kept to a minimum. All forms of stress are going to impact your CNS so if you’re highly stressed out in other areas of your life such as with financial issues, relationship problems, or otherwise, this will add up and reduce the amount of training load that you’re able to tolerate.
As much as working out is a great stress reliever, it may not be enough to counter all of life's problems. If you are having issues in your life that are impacting your stress levels to a high degree at a high frequency, then you must look into new ways of coping or bettering your situation.
Focus On Quality Sleep
Finally, the last must-do if you want to make sure that you are preventing CNS fatigue is to focus on high quality sleep. If you aren’t sleeping enough throughout the week, this is also going to influence the level of recovery you experience and take away from the total results that you see.
So there you have the top things to remember to prevent CNS overtraining. As long as you keep these in mind, you can be sure that you’re on the path to success.
