4-coachingBased on how much brain power is going into creating health and fitness technologies, you’d be surprised that there’s an obesity problem in this country.

Nearly every week we come across a new application in the health, fitness and wellness arena. This week, for example, we’ve already written about Mindbloom’s Proof which allows users to set up challenges to prove that they can run a mile or do 50 pushups.

Now, here comes another app. It’s called Cody, and it was developed by former Microsofties Pejman Pour-Moezzi and Paul Javid. Unlike services such as FitBit or Nike’s FuelBand, Cody doesn’t focus on measurement of every movement. Instead, the iPhone app, which is launching today, is a light-weight way for folks to share workouts with friends.

“Existing apps go deep on metrics and performance, including things like GPS tracking and route maps. This is great for enthusiasts, but intimidates the mainstream,” says Pour-Moezzi. He notes that Cody, which is the name of the virtual personal trainer in the app, is more about sharing than stats.

Just finished a grueling 30-minute session at Crossfit or completed a favorite yoga routine? You can post it on Cody, which is kind of like a Foursquare for fitness.

“Instead of sharing your location, you share your workout,” explains Pour-Moezzi, who previously worked on Bing at Microsoft and is now working out of the Founder’s Co-op space in South Lake Union. The company previously raised a $200,000 seed round, and is considering looking to raise new cash. It also plans to work on an Android app next.

Cody could face competition from existing social networks, including Facebook and Twitter as well as the online efforts of companies like Nike and FitBit.

“We are trying to build the social graph around fitness, and these other devices could integrate into it,” he said. “This is where you will set up your friends, which could be Nike users, RunKeeper users. It is going to get really fragmented with so many devices out there, and so you need that one central graph.”

As for those services like Mindbloom’s Proof which are trying to gamify the fitness arena, Pour-Moezzi thinks they will serve a purpose. But he thinks they are more for a niche-oriented and competitive audience.

“I think there will be a general fitness network, and then these guys will get folded into it,” he said. “The big question for the industry is whether it will be Facebook or a Twitter that do that, or will it be independent.”

Here’s a closer look at how it works:
