It's been pretty solid. Probably the first program I've actually tried following as I'm not very good with following through with these. Pretty good all around.

Love the set up. Got injured different locations. shoulder, trap, neck, got hurt after a heavy bench session. Back issues from unrelated causes. Elbow issues after heavy lying French press.

Restarting after an injury over 2 years ago. Slowly but surely progressing. Some lifts are way too easy but wanted to make sure I don’t get hurt again. GZCLP is always a good start for beginners. Very squat heavy tho. But who doesn’t like huge quads glutes and all that hahaha. (I prefer pecs and bis tho)

I found that GZCLP is a great program for strength gains. My strength had plateaued due to a lack of consistency in my training. GZCLP is a simple program to follow once you understand the progressions. I liked that I could get a high intensity, mostly full body lifting session completed in about an hour. My strength has improved immensely thanks to this program. I definitely gained muscle, but probably not as much as I would have on a program more focused on bodybuilding. That said, I have definitely gained muscle and people that I know have noticed. I would recommend this program to anyone looking for a simple program that will improve their strength and get them in the gym a few times per week.

Really good program and more importantly you can complete it with minimal equipment. It never felt too boring because of the two optional exercises in each session.

It's a good program as it allows you to progress different sets and rep schemes for the same exercise, so you can track weight independently. The rules are hard to follow, especially it is not defined what a fail means and how to continue properly. I'm going to run it again, but I basically split each session in two days, first I do the T1 and T2 exercises, the next day the rest, that works evst for my body.
