Think it's a matter of opinion? Turns out, a group of British academics have developed a mathematical calculation that will tell how close to perfect your rear is.

The equation is:

(S+C) x (B+F) /(T-V)

Here's how to use it: first assess your assets on a scale from one to 20 (score 1 worst, 20, best), and figure out your scores:

S = overall shape ( a ripe peach is ideal)
C = circulation (rounder is better)
B = bounciness (less wobble is preferred)
F = firmness ( too much push to cushion is not positive)
T = skin texture (no cellulite if possible)
V = the ratio of one's hip to waist.

Now do the math. According to one of the academics, slender thighs and a hip-to-waist ratio of 0.7 will frame the perfect butt. A score of 80 is want you want, so start working those glutes! Good Luck!!

oh my!

I'm pretty close, 76, its all my glute work and cardio and of course my clean eating.
