Well, this sounds like what I call stimulus addiction and its something that can really limit, if not completely halt, your gains.
It is true that the capacity to recover to training is limited. Just because you can “do it” doesn’t mean that it’s productive. Adaptation needs to take place.
Furthermore, training has both local (muscles being trained) and central/systemic effects (nervous system, hormonal system, immune system, etc.). Just because you train a different muscle at each workout (for example) doesn’t mean that you can train significantly every day.
If training everyday on the conjugate system worked, the Westside guys would have started doing that long ago. Yet they still “only” train 4 days a week.
CAVEAT/however, some of the Westside guys do include extra workouts during the week. But these are not full on sessions. It’s minor, non stressful stuff done to non-fatiguing levels. These workouts normally last 20 minutes, and often focus on sled work, high reps resistance bands work or low stress machine exercises.
But here is the problem: a stimulus addict will eventually turn these sessions gradually into “real” workouts and run into trouble.
You can actually train 5-6 days a week. But when frequency goes up, volume MUST go down. For example in my “Best damn workout for natural lifters” article, there are 6 weekly workouts. BUT each workout only has FOUR total work sets (not per exercise, for the whole workout).
In fact, at the moment I am training 6 days a week (when I don’t give seminars I train 6 days a week, when I travel I train 3-4 days a week). BUT I’m only doing one big lift in the session and 1-2 minor assistance exercises.
The problem with stimulus addicts is that lowering the volume will also be hard for them over the long run and they gradually add more sets in and eventually reach a point where it kills their progression.
So in theory if you want to train 6 days a week you can… IF:
OPTION 1 - you only do minor stuff, not anywhere close to failure. Things you can train:
Forearms
Calves
Neck
Abs
Sled/prowler
Farmer’s walk
Band work
Isolation/machine work
And the volume of these workouts should be low, the duration not exceeding 30 minutes.
OPTION 2 - Lower volume
Increase the frequency of sessions, but lower the volume per session. The higher the frequency, the lower the volume can be.
OPTION 3 - Neural charge workouts
These are short, 15-20 minutes. Only uses explosive exercises and there should be ZERO fatigue in the session (go read the article)
The problem is that stimulus addicts will likely turn all of these solutions into workouts sooner or later, diluting themselves into thinking that they can recover from it and grow optimally. But they can’t. Unless they are on drugs.
