Not all the way done but I like it so far, some small adjustments based on my personal goals.

In 6 weeks, my bench press improved from 1RM of 85lbs to 5 sets of 3 reps at 100lbs. I'm stoked by my progress. Definitely recommend this program if you've been in the gym for a little bit but haven't really consistently followed a program before.

Simple and flexible program to follow for beginners like me who only has time to workout in the morning. I was hoping for more noticeable muscle gains but I know its also because I’m not consuming enough protein or getting enough sleep. Highly recommended

About 6 weeks in I am enjoying this program. Good structure and I like that I am exercising each muscle more than once per week. I have added a lot of additional exercises to target areas that get less attention (esp arms) and to add some more intensity. I probably set initial 5RM too conservatively so have yet to work through the failure adjustments so can’t speak to how well they work.
