Do I rub coffee on my butt or exercise?

I may try the coffee.

According to Women's Health, a new trick to smooth out cellulite is to use ground coffee.   Natural beauty expert Renee Loux says freshly ground coffee works best.

Mix 1/4 cup of the coffee with 3 tablespoons of hot water, and let it sit for 10 minutes.  A paste will form.  Then mix in 2 tablespoons of olive oil to help bind the paste.

Clean the problem area in the shower, then apply the paste, massage in circles for 2 to 4 minutes, then rinse.
