Too early to give fair review. Consistency is easy though, I like.doing two compound lifts per day.

Great workout, Smartly planned well balanced. I really recommend to keep the rules, don’t increase workouts, it will bring results to beginner/intermediate

I had been training for 6 months when I started GZCL and have now run it 2x. I will continue to run it, switching accessories every 12 weeks. This program increased all my lifts but really helped me discover how much farther I can push myself. My squats and deadlifts really made big gains, around 70 lb increase on both. Starting at 85% of my 5 rep max really eased me into the program allowing me to work on technique before it got heavy. That being said, I had to run the program twice before I finally maxed out on both squats and deadlifts. I start my third round next week and am going to use 80% of my 1 rep max when resetting my Tier 1 lifts. I highly recommend this program as it has built in periodization and is structured to push you without burning out like a standard linear program.
