Used the 6 days a week variation for >2 months, still a beginner powerlifter with >6 months experience. However, the program worked great! Increased my bench from 85 lb to 130 lb (as of now and still increasing), my squat from 205 to 255, and my deadlift from 185 to 270. Part of it was due to that natural increase in strength when you first start out, but it did fix my muscle imbalance between deadlift and squat. Can be a little intense as I had to skip or lower reps a few times.

I like it. Easy to set up in the gym, not boring. Just not that many weeks yet, hard to assess results. I am focused on my relatively weak core now, this I am running for basics.

Bench has been going up steadily all upper body days I add easy movements like 20 rep band face pulls between sets. Lower body ive been doing my own thing due to past injuries.

I like the simplicity of the program. While I train mostly in my garage gym it is very convenient if you share a gym with other people as you do not have to move around so much. I added chin ups or pull-ups, as I think the pulling in the program falls a bit short. I also included a unilateral leg day with lunges.

I started this program at 32 years old. I went from a max benchpress of 205lbs to 320lbs, 315lb deadlift to 600lbs, 250lb squat to 520lbs, And 150lbs OHP to 240lbs in about 3 years. I like working with percentages personally, they keep me honest and make me push harder. Modifications I made to improve my recovery ability. On squat day I do RDLs 4x10 for accessory. On Deadlift day I do Goodmornings 4x10. If I hit 15+ reps on last accessory set increase weight by 5lbs next workout. This program gets tough the further you advance. What I found worked well for me was deloading lifts by 15% if I failed to hit all sets for 2-3 workouts in a row. Deloading by 15% and slowly building back up usually lead to new PRs each run. Eventually you hit a point where you're scraping to add a pound to your lifts while risking injury. That's the name of the game. Enjoy the process and know when it's time to switch your goals to something new. Push yourself to see what you're capable of, there is something beautiful in that process. Cheers.

This program was amazing. Havent trained for 6-7 months seriously. When i broke up with my Ex, and joined the program in hopes of just kickstarting my CNS, this blew my mind. My Squat and Deadlift are almost fully reset to my prior PRs. But my bench surprised me much more. (Note, I pretty much did the program back to back working out 6-7 days a week, with only a little rest day sometimes.) anyway, my bench went from a rusty hard 80kg being difficult. To, repping 100kg with much more ease than ever. Prior to the program, and relationship. So a year ago. My bench pr was 105. These 8 weeks made it jump to 115 fast rep, on the edge to 120kg Bench. I loved this program and I will definitely do it again. It made me enjoy working out again like never before

If you are trying to actually get up your compound lifts, this is exactly the workout you should do. 10/10 strength gains.
