That’s not it, the article you shared is a program that last only 4-6 weeks.
It’s also a program that has both a brutally high frequency and high training volume.
Unless you are enhanced or have an amazing tolerance to high volume training sessions, I would not do this program or at least modify it.
I counted 36 sets in one training session that was not whole body. A lot of lifters can’t even sustain that amount of volume in a maintenance or bulk period, let alone while cutting.
EDIT: Well OK, on the pump days you have supersets and trisets so the 36 sets could actually mean 15-18 sets because the supersets and trisets count as extended sets. But even then the total weekly volume would still be between 90-100 sets.
I can vouch for https://thibarmy.com/product/get-back-in-shape-blitz-program/ ; really good program. I’ve edited it for a 2nd go round (against advice etc); but 1A/B etc dual exercise pairings are alot better than 1 straight exercise (for me, anyways).
