Looking for the perfect holiday present for a fitness fan? Gift offerings this year range from apps that can store a run in the country to be viewed later to gadgets so sophisticated they measure quality of sleep as well as calories burned.
There is also the revival of the humble foam roller, which experts say, like old-time push-ups, squats and planks, has never been more popular.
Anita Golden, fitness manager at a Crunch gym in New York City, said she'll be giving clients a foam roller called the GRID.
"We've always had foam rollers in the club but now more people are using them as a way to ease post-workout muscles, prevent injuries and exercise the core," Golden said.
When it comes to big-ticket items, Colleen Logan of Icon Health and Fitness, which manufactures a number of fitness brands, said the treadmill remains the most popular gift.
"Treadmills continue to lead the industry in terms of home fitness purchases," said Logan.
They account for about 57 percent of fitness purchases, while elliptical trainers and stationary bicycles are a distant second and third place at about 8 percent each.
The average home treadmill costs about $700, said Logan, but the technology revolution has transformed even this stalwart at the high end.
The ultimate splurge, at $4,000, she said, is the Boston Marathon Treadmill, which allows users to adjust speed in 1/10 of a mile per hour increments without touching the console.
It also lets users run a virtual Boston Marathon.
For people on a smaller budget, there is the iFit app that lets the iPhone capture a favorite vacation run or bike ride in Hawaii, store it in data centers all over the world which collectively are referred to as the "cloud," and download it to an iFit-enabled treadmill at home.
"You'll view the exact route and experience the same terrain again," Logan explained. Devices, gadgets and apps proliferate as tech-savvy fitness becomes more accessible, according to Jessica Matthews of the American Council on Exercise (ACE).
"There's a lot of interest in on-body monitoring devices as ways to motivate and track progress," she said.
"They run the gamut from basic devices to track hours, steps, and caloric expenditure to full-body tracking."
