Nice program, if you want to start it make sure to perfect your technique on the 3 main powerlifting lifts before starting it

This program is great for new lifters, albeit the full body aspect can be very taxing, especially if you have absolutely no prior lifting experience, I would suggest being very conservative with imputing your 5rm, and following the program protocols. I had some inconsistent experience prior, so I went with the 4 day a week version, and added in exercises that I wanted to get better on. I did add in pull ups as a finisher on the vertical back days, mainly cause I wanted to get better at the them. I was a bit extra conservative with my 5 rep maxes so the strength gains I made probably aren’t really that accurate as these were estimates based on 1 rep maxes I made. Especially on my deadlift and squats (i personally dont like doing them so I didn’t put in much effort when testing my maxes on them) however, in terms of the gains I made, after completing 9 weeks I still haven’t failed on my t1 exercises Bench = 95lbs 5x3 to 135lbs 5x3 Squat = 115lbs 5x3 to 205lbs 5x3 (just did day 1 of week 10) Ohp = 40lbs 5x3 to 80lbs 5x3 Deadlift = 155lbs to 235lbs 5x3 (it’s my strongest lift and I really underestimated my strength when inputting my max, I also estimated this one cause I I managed to deadlift 225lbs at 16 for 5 reps and I was about 155lbs at that time, so I made an estimate as I was lowkey lazy af and didn’t wanna go for a deadlift max test, and after 245lbs for 1 I just made an educated guess of what it was. Body weight - 127.5 (started at 123.8lbs) I’m 5’6” 21 year old male for reference I will say I can see my bench and ohp failing first, as they have already failed in my t2 exercises, However I definitely see myself running this program for as long as I can mainly for the flexibility and the experience I get in different rep ranges, and you can also swap exercises as you please as well which helps a lot, I will say I skipped the t3 optional squat leg exercises every week mainly due to how taxing they felt ( I struggled to recover from the volume, I don’t think everyone will suffer from the volume, and prior to this I mainly did low rep ranges for squats, so it was definitely very taxing, I think it’s definitely something you can get used to though. I definitely recommend this program to beginners as the philosophy makes sense, and as someone that wants to get stronger but also work towards an aesthetic physique, I would say this program definitely helps. Also milk this program for as long as u can, cause im pretty sure the rate of progress you make now will definitely change after about a year.

Significant modifications

I’m almost done with my first gzcl program and I’ve seen significant muscle growth. I wanted to do this as a way to raise my strength and I feel stronger but not as much as I was expecting. I’ll do a deload and try another 12 week program now that I’m used to the volume and see how I feel after.
