In contrast to Hunyuan strength, regular strength would be called sectional, broken or one-sided strength. It is not to say that regular strength can't be strong and forceful, only that the entire body is not contributing to whatever function the strength is required for. With regular strength the majority of the load is born by the local muscle groups in the limbs. With Hunyuan strength, the majority of the load is carried by the legs, waist and back. Regular strength is delivered directly, like a ram where the force is the inertia of the weight moving forward. Hunyuan strength is delivered indirectly... the inertia of the weight moving away from the target is more than that moving into it.
So, as a student of Cheuk Fung, *how* is it done? I personally think that all of these various descriptions can be reconciled (the ones that are correct power and not just talk, of course).
