In the situation of hypertrophy, is the total weekly volume still what matters even if you’re not able to keep the muscle groups together ?
Example , typically on my deadlift day is leg press / lunges and GHR. But I was stressed for time and decided to skip the ghr and
will do it tomorrow , will that still yield the same
results as if I did it today ?
Will this specific example yield the same results? Probably, because it’s one lift of one day on one week and overall is trivial.
If you’re asking if both scenario are equivalent from a stress perspective then the answer is no because there was pre fatigue from the other lifts.
All that being said, it is better to get the training in than not, but the program you’re outlining doesn’t sound like something I would recommend overall.
