Thanks for the technological emotional support. I'm afraid I need it.
Under 5-3-1 you reset your max when you are not progressing anymore--ie you're not able to add weight and hit the reps you need through your next cycle. So, you take a step back so you can move forward. I like to think of it as getting a running start, which helps you break through a wall. But, I've tended to keep my "max" for each lift at a weight that I can hit for 4 or 5 reps. That approach hasn't really allowed me to make forward progress. As hard on my ego as it is, I need to make more of an effort to truly train submaximally. Someone else may be able to explain this better, but that is how I understand it.
I've heard that the running works against me with respect to strength gains. I don't really worry about that though. I love running. And I've been running my whole life. The strength training has made it even more enjoyable. I'm so light and strong; it often feels effortless, and I am running better than I ever have.
I am also really committed to the lifting. I struggle to balance all of my activities with each other and with the demands of my life. My schedule is not ideal, and I often end up compressing more physical activity than I should on my weekends. I'm trying to do better with that But I'm having fun, and feeling good.
