So are a lot of other runners, bikers, swimmers, and people just trying to lose a few pounds, as "wearables" - computer chips that, at a minimum, track steps taken, distance traveled, calories burned, and sleep had - continue to climb the It-o-meter in fitness and fashion circles.
Fitness tracking chips hit the market in the early 2000s, but they were geared to the techy fitness buff. I once tried attaching a chip made by Nike to my running shoes, but because I couldn't get the darned thing to sync with my iPod, I threw in the shoelaces pretty quickly. Then they were made to look like pedometers. Clearly, function trumped fashion.
This year, however, sales of activity trackers topped $100 million during the first quarter, according to the market research firm NPD Group. In 2013, total sales were $283 million.
"There's such a focus on fitness and how it integrates into our lifestyles," said Ben Arnold, industry analyst for NPD. "Trackers can monitor our heart rate and can tell you how long you've been in the sun. The new features are bringing the trackers into the next phase."
It also helps that the trackers - the Jawbone, Fitbug, Pulse, Fitbit, and market newcomer Misfit Shine - are becoming trendy must-haves like the recognizable Starbucks coffee cup, Bloomingdale's brown bag, or lululemon's horseshoe insignia.
"A Fitbit or [Nike] FuelBand says 'I'm active, I like to work out. I'm healthy.' There is an inherent status symbol in that," Arnold said.
And where there is cachet to be claimed, fashion is never far behind.
The most talked-about tracker-meets-fashionista collaboration of the year is between San Francisco-based Fitbit and Main Line-bred Tory Burch. Someone on the Tory Burch team, which apparently has a lot of Fitbit wearers, reached out to Fitbit cofounder Eric Friedman. After a few months, the companies settled on a golden cuff bracelet and pendant that can hold a Fitbit sensor.
"These are designed to be high-fashion accessories that can take your Flex tracker from day to night," said Melanie Chase, product marketing manager at Fitbit.
Misfit introduced its Shine tracker (battery-powered, so it doesn't have to be charged) in August 2013 with fashion in mind, said founder Sonny Vu.
The circular, hand-polished stainless steel tracker can be attached to a wristband or worn around the neck as a large pendant. It comes in 12 colors, including a blue one that resembles a piece of turquoise.
"It's perfect for business casual and dressy attire," said Vu, who introduced a flowery stainless steel necklace holder called Bloom in early May. "We wanted to make something that people would enjoy wearing."
There's also a race to marry tracking devices with apparel. Misfit sells T-shirts and socks with snug pockets for the Shine. Seattle-based Heapsylon introduced its Sensoria sports bra and shirt (both $79) earlier this year with sensors embedded in the fabric. Heapsylon will introduce socks in July; four pairs for $199.
The question is: Do trackers provide accurate data?
The consensus is that they work best when worn on the wrist.
In the newsroom, we tried the Fitbit Flex ($99.95), the Fitbug Orb ($49.95), and Withings Pulse ($99.99).
All three were pretty good for counting steps and keeping up with miles. Our Orb user liked how her device calculated how many of her steps were aerobic and became obsessed with getting 10,000 daily steps; in fact, she surpassed her goal every day.
I continually tapped my wrist just to see how many LED bars would twinkle - each of the five represent one-fifth of my 10,000 steps. (I tapped even when lying on the couch.)
They may be great at tracking steps, but other workouts prove more elusive. Although my Fitbit Flex was waterproof, I was too chicken to swim in mine, so Friday morning's workout was a wash. The coworker who used the Pulse never made her step quotient despite intense yoga sessions and 10-mile daily rides. She felt judged by her Pulse.
That said, she was impressed with its sleep tracker. She thought she was getting some good zzzz's until her morning stats informed her she was awake more often than she thought.
One night - maybe I tossed and turned a lot? - my Flex showed I could have been walking while sleeping.
Either it's a little bit off, or I've just learned something new about myself.
