After 10 years of trying, I did my first pull-up thanks to this program.
That means - Jeff, you are doing some good work.
As I mentioned, I have been going to the gym for about 10 years, so I wasn't expecting any great changes in my physique. Boy, was I wrong.
My lats grew few centimeters wider, my back has a definition it never has. Honestly, I can stop looking at it, the difference is huge.
Also, the pull-up!
One star down due to lack of alternations, but you can find them in Jeff's newer programs. I have alternated some exercises due to lack of gym equipment (also I really didn't want to lay on the ground), but less experienced lifter might run into a problem.
Overall - if you already have some experience at the gym, this is a great, great program. Fully recommend.
