Would you guys ever use general strength with speed if you don’t want to hit the gym? And lets say you do speed endurance, would it be complimentary to do something like 3x20m walking lunges?
Coaching is part science and part art so why not? Learning from the science will help in constructing a program that hopefully optimizes performance and minimizes risk of injury. To me, your question falls under the art part which means it isn’t a dumb question and you could do it. In fact, if you’re training younger kids, then the “general strength” could become “strength” period and you’d certainly do that after speed.
