Yes. It's a long term plan, and an illustrative exaggeration. I don't expect a 34 year old designer at a software company to actually enter the NFL combine. But I want to reach for my max potential over the next few years. I'm 34.
"Max potential" will not happen in a few years. It will take a decade or longer. But yes, you will make astounding progress in the first couple of years assuming you stick to a proper meal plan (even if that's Soylent and hitting the right macros) and train appropriately (progressive overload).
I just want to reach for it. I don't need to hit it. I have a personal trainer 3 times a week who does HIIT and conditioning, with some weights mixed in but not as the focus. And then the endurance cardio I do on my own. I'll probably stick with the trainer for quite a while, I learn a lot and it's so convenient as the gym and trainer are at my workplace, it's a real sweet setup.
