It wasn’t a comment about this specific routine but more a reply to the GP.

One of the reasons why I don’t like this specific routine is that it doesn’t stretch under load, to actually improve mobility your stretches need to be accompanied with a dynamic load such as body weight, balancing, free weight or a resistive band or cable.

I also do not think that a routine that does not have a test to identify which muscles are too weak and which are overused and one which does not allow you to set specific mobility goals is going to be productive either.

I guess I agree and disagree with that sentiment. If you do at least this routine frequently, it'll probably be a good thing, but you won't necessarily progress anything in any measurable way.

Whenever I know someone who wants to become a bit stronger or feel better, but hates the routine or gym or doesn't feel like they have time, I always recommend just showing up to a gym as frequently as you can, but 3 times a week is a good number. You can't optimize what you aren't already doing, so it's not really necessary to tell someone to fet into any particular exercise until they're there and feel comfortable with that.

To that effect, this routine doesn't seem like it's for someone who already has literally any existing training experience, it's for someone who sits all day and doesn't really have anything in movement.

As for my comment, I just mistook you for OP, it was early.

I personally love pullups, bench etc.. and that changes over time, but I'm usually chatting with people at the gym and making connections, which inspires me to try what they're doing and keep the habit strong. If I wanted to apply more rigor to it, I'd probably note my progress in some meaningful way, try to ingest more protein, pay attention to more detailed nutrition elements, but that's like a tertiary optimization that doesn't interest me too much.
