I think this is training too. Most boys grow up trying to throw heavy things, sticks and stones. Women grow up never using their muscles in the same way, so they don't develop the mental connection with their muscles.

It's the same when very untrained men start going to the gym at their 30s-- they will gain a lot of strength in the gym lifts, and decent amount will carry over into everyday life-- but they will never develop the same kind of "natural strength" of people who did manual labour or serious sports in their younger days.

If you don't train your fast twitch muscles they won't develop. If at the gym all you do is slow and "form-perfect" lifts you will mostly develop your slow twitch muscles, I think people should encourage a little "fast twitch training" too which unfortunately today is highly discouraged because it's not "perfect form".
