Gear Guide: NextFit Keychain Trainer Personalized Fitness Coaching


By Su Reid-St. John
I love the idea of exercising with a personal trainer, but as a working mom on a tight budget, it’s not really an option, either time- or money-wise. That’s why I’m loving this trend of “virtual” trainers: You download programs designed by experienced trainers to help you achieve your fitness goal, then do the workouts on your own time—all for a monthly price equivalent to that of two or three sessions with a live trainer. Time to test the newest entry in this crowded field, the NextFit Keychain Trainer.

The Keychain is about the size and shape of a cigarette lighter, and it can indeed go on your keychain. To keep it close by during your workout, it also comes with a lanyard and an iPod-style armband. (Take my advice and go for the arm band—hanging from the lanyard, the Keychain bounced annoyingly against my chest while doing the moves.)

When I first plugged the Keychain into my hard drive to download my program, I was taken directly to the sign-up page. I was asked a series of questions: my goal (“Shape and Tone”), BMI (body mass index, which they helpfully calculate for you), fitness level, workout experience, and preferred activities—plus, where I work out most, what equipment I own, and how long I want my workout to last. All good questions.

After registering my answers, the website gave me three program recommendations, each from a different “star” trainer. I chose the first option, a weight training/body-shaping program with Kathy Smith, star of a gazillion workout DVDs.

Then I clicked to download my first workout. And waited. And waited. It took about 10 minutes to load, which seemed like a lifetime on my usually speedy computer. (But, hey, at least I didn’t have to take the time to drive to the gym to meet with my trainer.) Downloading subsequent workouts took just as long, but were admittedly easy to do—I just plugged the Keychain into my hard drive, clicked on the NextFit logo, and was taken directly to my personal page where my next workout was waiting for me.

One of the cool things about NextFit is that they don’t just pair you with a trainer; they give you a choice. After three workouts with Ms. Smith, I was ready for a change—her tendency to vacillate inexplicably between cheerleader and let’s-get-it-over-with modes was beginning to annoy me. So I switched over to celeb trainer Ron Mathews, who turned out to be much more my speed and style, and whose workouts are a little fresher. Options are a good thing!

Another thing I appreciated: Each time I came back to load subsequent routines, I had the option of clicking on a link called “Improve your workout.” How could I resist? I was taken to a page where I was asked about the previous workout’s moves and intensity, plus whether I wanted full instructions before every move, how much motivational chatter I wanted to hear, even whether I wanted to hear my name or not during the session (no thanks—too contrived). I found it to be a really helpful way to make my workouts more like I wanted them to be—in other words, some different moves, more intensity, and fewer instructions and rah-rah talk.

Aside from the lengthy download time, I found only one thing not to like about the NextFit Keychain Trainer, and it’s minor: the earbuds. Now I’ll admit that my ears are a bit on the small side, but earbuds usually at least fit into them. These did not, despite persistent cramming. So I finally gave up and switched over to the ones I use with my iPod—problem solved.

Usually when I test this kind of product, I leave it behind once I’ve written my review. Not so this time around—I’m fully planning to continue following Mr. Mathews’ workouts throughout the rest of the month. And who knows? I might even renew.
