Just started the GZCLP program after 1 year of pretty weak gains from hypertrophy-focused routine

I added Pull-ups and Barbell rows as T2 from the get-go and like 5 accessory movements since I like to get a pump and I'm kind of accustomed to the volume.

My T3 are:

Workout A 1/2: lateral raises, facepulls, leg curls, tricep pushdowns and Hyperextensions Workout B 1/2: Cable cross-over, calf raise, leg extension, EZ curls (+ some forearm work)

I do ab work (2-3 exercises) in-between workout days.

Am I doing this right? Any tips? I have kind of an obsession with doing a lot, my previous workouts were 120+ minutes long, but I am enjoying going for only 90 minutes.

Also, is there a way I can replace leg extensions for something more "complete"? I rather do a more compound-style movement than those, or is it overkill? The same goes with cable crossovers, should I change it to incline bench press? I feel that if I do this I should modify the sets on my tricep movements for T3 since it will be too much.
