Condensing Hypertrophy I from 5-days to a 4-day Program

Hello, I just bought the Hypertrophy I program and am looking forward to starting it next week after a deload. I would like to know if I can set it up to a 4-day program instead as it fits my schedule a bit better. I’m new to the GPP concept so I’d like to know how that fits in there.

Monday:
High Bar Squat
Seated Barbell Overhead Press
Lat pulldowns (this can be substituted in as a “Supplemental Pull in place of RDLS”?)
Leg extensions
Arms GPP

Wedenesdat:
Larson Press (had a pec injury in Novemeber so wanting to use lighter loads)
Leg Press
Low incline DB bench press
Cable flys
Upper Back GPP
Abs GPP

Friday:
Good Mornings
Close-Grip Bench
High Incline DB press
DB lateral raises

Saturday:
Upper Back GPP
Arms GPP
Abs GPP

Steadt-state cardio on off-days.

Is this a valid way to set it up? The Hamstring and Lat volume seems a bit low, no? Is there room to add leg curls and back extensions? More vertical pulls? Haven’t done any conventional heavy deadlifts in awhile due to the pec injury I didn’t want to pull heavy loads. I’ve been doing Good mornings, back extensions and leg curls in the meantime. Somehow even doing Ab Roller the other day brought back a bit of nagging pain. Seems to have recovered well, though.

I think it’s fine to mix and match GPP stuff as needed to get it all in.

I don’t think the hamstring, lat, or vertical pull volume needs adjustment. You might find that trap bar DL is accessible for you vs. good mornings.

Thanks Jordan, I will follow as close as I can to how the program is laid out. I like trap bar deadlifts a lot, only issue is the one at my gym is one of the smaller ones that can’t fit too many plates on either end.
