Khloe Kardashian first coined the term "revenge body" after she took up exercising as a form of therapy when her marriage to Lamar Odom went south. The concept is to totally transform your body to show your ex-significant other exactly what he's missing. This premise and Khloe's success with it has lead to yet another Kardashian led reality television called "Revenge Body."
The idea of working out for the sole power of showing an ex that he threw something [insert term for beauty, hot, and better looking here] is ridiculous. The notion is under the guise that it is empowering when it is far from it. My mother used to tell me that looks last only 20 minutes. Chances are that there are other reasons that you and your significant other didn't work out that aren't skin deep.
So what is empowering? Working out for yourself. If you want to work out because you want to feel healthier and feel better then that's a form of self-love. Changing yourself for the sake of getting back at someone for breaking your heart? Not so much. You shouldn't be hell bent on getting revenge on your ex.
When promoting the series, Khloe says, "Looking great is always the best revenge." No, it's not. You could be more successful. Or you could stop being so petty and get over your ex. Or maybe, you can learn to be more content with who you are. I'd like to think that the best form of revenge is just being yourself for yourself. Be unapologetically you. Don't think about what the ex thinks about you because you'll never be happy that way.
So if you want to be empowered, do things for yourself. Focus on your own confidence and security. Don't worry about your ex and whatever they're doing. Just focus on yourself, your friends, your family, and your own happiness. That's what empowerment should look like-- building up yourself and those around you.
