Only 4 weeks in, had to start at lower weight than usual due to the percentages. Finally starting to feel like I’m pushing more weight. Gonna continue the program for another 4 weeks and see how it feels then.

I liked how modular it is. I can easily swap out t3 exercises for wtv exercise goals or fitness goals I had.

Gained a lot of muscle mass quickly on this program. Strength gains are marginal, but could definitely see strength blowing up if I hopped on a powerlifting program right after finishing this! Loved how it was able to help me break my year long bench plateau!

Really fun program with great results. I love the different rep schemes - prevents boredom and I got better than expected strength gains. Recommend reading through the program overview to understand the failure protocol. It’s super simple, I just didn’t realize that there was more info to be found there, and it’s definitely helpful. Highly recommend.
