Personally, I think in the long-run, a hybrid approach to training is a more efficient and effective systems training method than sole focus on power or max strength.
Here's a grid that I use for planning purposes keeping the hybrid idea in mind. This tool provides me a means to keep it simple, but maintain a precise focus. I keep copies in my coach's planner and have real-time access to work on training ideas and then test before rolling them out. Even after, I want to know, "what is the response?" I also maintain a file of these grid-cards for future reference.
I may not fill out every block during every session, but the construct helps me to keep seeking True North.
