Best $20 I ever spent on anything related to bodybuilding.
I highly recommend you invest the time in reading and understanding it. The beauty is that it is a system that provides structure, yet leaves plenty of room for choice.
I've strayed away from following specific training programs in the past few years as I have some injuries that make specific movements very difficult to do.
This is not a problem in Fortitude, as there are no specific exercises prescribed. You're not forced to do overhead press for shoulders, for example, if that is a movement that bothers you.
I also love the variety it provides, as executing the same exercises for 8-12 reps every week can get very boring and lead to plateaus. Each of the 4 workouts is very different, and each week is also different, as you increase or decrease the volume, or change from basic to turbo.
Lastly, the autoregulation component of the program is what really makes it special. You decide how long your "blasts" last, where you are really pushing for all out progress. You decide how much volume you'll perform each week. You'll decide how and when to increase or decrease the volume. Of course, Scott provides guidelines and tips to help you make these decisions, but it is up to you.
In the past I'd do a program and due to outside stressors, being in a caloric deficit, etc. I'd fail to progress as I was supposed to after a while. Those programs did not have a "here's what to do if your progress stalls" section. There was no autoregulation. It was "here's how you should be progressing - period, end of story." So I just kept grinding out the same weights for weeks on end and burning myself out.
For those asking for summaries, or explanations of how it works - I like free stuff too. I'm not rich. But, I plan to adhere to this system for years to come.
I almost never review any sort of product or service, but I have gotten so much value out of Fortitude, that the least I can do is share how it has benefitted me.
