In the United States, plastic surgery to remove excess fat and skin on the upper arms has gained appeal, say experts.
More than 15,000 US women had the procedure known as arm lifts, or brachioplasty, done last year, at a cost of $61 million nationwide, according to the American Society of Plastic Surgeons.
The surgery is most popular among women over 40, but a few hundred men had the operation last year.
Doctors say there is no single reason why, but experts believe the desire to emulate celebrities and their super-toned arms may be a factor.
The ASPS pointed to a recent poll that suggested "women most admire the arms of first lady Michelle Obama, followed closely by Jennifer Aniston."
"I think we are always affected by the people that we see consistently, either on the big screen or on TV," said David Reath, a doctor in Knoxville, Tennessee who chairs the ASPS Public Education Committee.
"We see them and think, 'yeah, I'd like to look like that.'"
The average cost for the operation is nearly $4,000. Upper arm lift procedures may involve liposuction or cutting away excess skin.
But Reath cautioned that there are drawbacks to brachioplasty, which requires an incision from the elbow to the armpit.
"It's a trade-off. We get rid of the skin, but we leave a scar," he said.
"So, as long as there's enough improvement to be made in the shape of the arm to justify the scar, then it's a great procedure."
