So I just started Foundation One, and one thing stood out to me. I've done some weight training in the past, and whenever I have done so it has been important for me to maintain a balance between horizontal push/pull and vertical push/pull. The concern I have especially regards the bent arm work. It seems to me that, since I will only be doing one exercise per three months (for example rows and pushups) for pushing and pulling respectively, this will create an imbalance, or not involve all my planes. And while I understand that these exercises will come later, if I only do one at a time, I will lose any progress I made in the last progression (and in that related plane) as I work the new one. It says in the introduction that I should add a previous exercise as a warm-up, but it doesn't specify which warmup exercise should go with which main exercise. It seems very arbitrary, and not as if this point has been taken into account.
Thoughts?
