A question i have that I haven’t seen fully explained is why you have to train only after you have fully recovered when training separate body parts.

I understand CNS fatigue, and I understand growth happens at rest, but the part I struggle with I guess is why can’t the body do both at the same time.

For example, let’s say you do legs Monday, and they aren’t fully recovered by Thursday, but maybe 85%… then you blast Chest….

Obviously now the body is recovering both chest and legs at the same time…

What I’m getting at is that I understand by training chest before the legs have fully recovered means the legs still haven’t grown, or overcompensated, but why can’t this happen still over the next 3 days alongside the chest.

I guess one would assume Mentzer would just argue it’s not optimal based on client experience but it would be nice to know for sure if this worked also, and of course which is truly more optimal.

For example let’s say you’re doing push pull legs with 2 days of rest in between… maybe your not fully recovered on each body part during the week, but once you complete the rotation maybe give yourself another day or 2 to get over the accumulated fatigue before starting the rotation again?

Could you get better frequency while maximizing intensity and recovery… can the body do multiple things at once?

I’m up 66% on lower body reps in 3-4 weeks already. (Squats/Deadlifts)

Week 1 squat 205- 1 set of 12
Week3/4 squat 205 1 set of 20

This stuff definitely works. But you do need a lot of rest if you’re taking things to true failure. I’ve been surprised how long it takes to recover.

Also the mindset of having to set a record every week is gold. I’ve probably done countless wasted volume in my life.

To be fair I’m a former athlete so some of these gains are muscle memory to be sure, however still surprised at how fast it’s progressed already. And still getting used to training 2 to 3 times every 8/9 days.
