Strength has a greater purpose.
The Kettlebell is an Ancient Russian Weapon Against Weakness

If you are wondering what 'strong' is, it is probably not you.
If you think you are only strong if you can lift a certain number, whatever that number is, you will feel pretty weak most of the time. Strength is not a data point; it’s not a number. It’s an attitude.
You can be anything you want… But you must be strong first.
