Long title. Longer question. I'm not going to pretend to have the answer either. I believe that like most things fitness related, there are multiple answers and models that will fit one person but not another person.
My goal is to find the best model for me. I have been looking for the model that will give me the best blend of strength, agility, and endurance. It's a hotly debated topic and there are several philosophies out there.
Over the next few weeks I hope to summarize many of those schools of thought here.
