Perhaps unsurprisingly, breast augmentation is the most popular procedure. Plastic surgeons performed this particular operation 290,000 times in 2013. That's 580,000 breasts that are now bigger. Following somewhat close behind is nose reshaping (221,000) and eyelid surgery (216,000). And, in the spirit of trend forecasting, it looks like buttock augmentation and neck lifts are on the rise.
Of course, if you're looking for a nonsurgical way to improve you butt, we recommend you just try these exercises. (Time)
