Simply put, when you empower someone, you give them the tools they need to do something. It can be spiritual, educational, or physical.
The ability to move your body a certain way, or being able to physically endure something gives you power. It makes you feel strong and accomplished. As a fitness instructor I feel empowered because my group fitness class is the one place where I can command a whole room full of people to move a certain way, when I say. Looking out at the faces in the room, seeing their smiles, their eagerness and joy is empowering. I did that!
Improving your level of fitness can be empowering. Every week you push a little harder and you eventually begin to notice that your form is improving (you're getting stronger), you're clothes are looser (you are losing inches), you're breathing a little easier (your endurance is improving), you're eating habits are improving and your sleeping better. That's Empowering!
