Ok. If you are 150kg just walking around you will get stronger than if you are 50kg
If you are 50kg you will get stronger if you lift weights than if you don't lift weight. There is nothing you can do about other people but you can do something about you. So I don't know how inherent ability is a factor in your martial arts training.
Not generalist. Not even my idea. A whole thread full of people saying strength training makes you a better martial artist. All different styles and different cultures.
Which basically makes it an accepted idea in martial arts circles.
Martial Arts circles which is you! You are always citing others
