So much emphasis is placed on the efficiency of a system. Most people focus on techniques—and proving that their techniques are better than someone else’s. Sometimes that difference is obvious. But techniques alone don’t determine whether a system works. The training method matters more. It must reflect the reality of who we teach: 1. Most of our adult students are 35+. 2. The average student trains twice per week. 3. Their average fitness level is low to moderate. A system has to work for real people, training under real conditions—not just for highly athletic instructors who train every day. The question isn’t only, “Does this technique work?” It’s also: “Can we teach it, retain it, pressure-test it, and make it usable for the average student?” That is the difference between teaching techniques and teaching a system.
