I see the “training” thing is still circling the drain of the Internet, refusing to go down. Maybe I can throw some gasoline on the fire.
Training is repeating an action until it becomes muscle memory. You can’t train for the unknown. You can only train for known, specific actions. Dry fire practice is training. Practicing your draw from a holster 10,000 times is training. Shooting hundreds of rounds a week is training.
Taking a class is not training. You may use the knowledge you gain from a class in later training but I’m betting you won’t. Nothing wrong with that, some classes are just fun.
But classes are not training.
