Prowess is the engine of chivalry—but without purpose, it corrodes. Drawing on themes from Chivalry: An Ideal Whose Time Has Come Again, we explore how true prowess blends physical training, technical competence, moral restraint, and service to others. We link the gym to the grail: daily habits, drills, and mindset work that turn strength into stewardship. Win the inner fight first; then use your power to protect, not dominate.
