I actually just finished writing an article on that subject. Overtraining does exist. But it is extremely rare. And it DOESN'T mean "training too much".
Overtraining is a syndrome and in many ways is similar to clinical depression. It is a physiological state, not an action.
I will be honest you are probably not overtraining. In my whole life I've seen 3 real cases of overtraining and I've worked with hundreds of athletes whop trained 20 hours or more per week.
Every stress can contribute to developing an overtraining syndrome. Physical, psychological, environmental, social, etc. Excessive training is only one contributing factor.
Real overtraining takes months to recover from.
Now, you are exhibiting symptoms of a problematic issue. But it is not likely overtraining. See you have three main systems involved in training adaptation/recovery.
The nervous system
And while they are independent they do work together and play important roles in adaptation to training.
From the symptoms you are describing you are likely overtaxing all three systems. The loss of libido shows that your testosterone levels are dropping and this is likely due to excessive production of cortisol due to improper (too much) training. See cortisol and testosterone are fabricated from the same mother hormone (pregnenolone) and over producing cortisol leaves less of that mother hormone to produce testosterone.
The lack of motivation to train is indicative of neural fatigue and could also be a problem with your immune system. An overtaxed immune system will leave you feeling sluggish, almost sick-like.
Your description of your training is not clear. But it sure seems to me like you are doing a ton of volume if you count the lifting and energy system work. That is likely the problem. Doing too much.
And if it is high intensity work on top of that you are not giving yourself any chances.
You mention started training again 2 months ago. Yet from your volume of work you have an immense training stress imposed on a body that is not used to training anymore.
You are just doing too much. Hard heavy lifting and hard energy systems work in the same session could be too much. And your lifting volume could be too much to depending on how many lifts you do per session.
While a supplement like PLAZMA will help you recover faster physiologically from your training it will not be able to solve the issue if the problem is excessive training stress.
Rhodiola will help boost your immune system and make your body better at tolerating stress. But my gut feeling is that you are doing too much for your level of fitness.
You can't use the same protocols as advanced people using drugs
You can't use the same protocols as those with an ironclad immune system that can tolerate stress more than regular people
You can't use the same protocols as pro athletes who do not have much stress outside of the gym
You can't use the same protocols as genetic freaks who can tolerate hours upon hours of training.
Not everybody is the same. This is true for one's capacity to build muscle, strength and power but it is also true for how much volume one can recover from. If you are feeling like crap, you are exceeding your body's capacity to tolerate stress. Do less. It sucks but that's just how it is.
I am finding this out myself. I had serious health issues and now I get the symptoms you mentioned if I do too much. I used to be able to train for 4-5 hours per day and feel good. Now I can't do 1/3 of that and feel good. It sucks because I love to train, but I have to restrain myself because I have more limitations now.
Changing your body is an emotional issue. We want to change RIGHT NOW and because of that mindset we end up doing way too much and sabotage ours gains and well-being in the process.
