At the end of 2014 NBCUniversal launched a new digital fitness offering, called Radius. The multi-platform service provides consumers with unlimited access to fitness videos for a weekly, semi-annual, or annual subscription.

The media conglomerate's fitness app, available on iPads and iPhones, is part of a multi-platform fitness offering from the company. Subscribers can also access Radius via the web or during a three hour weekday block of programming on NBC Sports Network.

Radius offers a range of workouts, from yoga sessions to high intensity training. The app tracks the user's achievements based on goals the user chooses in the app. As users continue to workout, the app will update their progress.

Along with the launch, NBCUniversal announced a partnership with Under Armour. As part of this partnership, the two companies will create original content for Radius and also integrate Under Armour's connected fitness offerings into the app. 

"Radius marks an exciting evolution in the industry as we make premium fitness accessible to anyone, anywhere, anytime by leveraging our media platforms, technology, and partnerships," NBCUniversal President of Digital Nick Lehman said in a statement at the time of launch. "With fitness at the epicenter of today’s pop culture, now is the perfect time to introduce a new media brand that can capture and drive the explosion of innovation in the fitness space."

At the time of the announcement, Radius could sync with MapMyFitness, an app Under Armour bought for $150 million in 2013. Then, earlier this year, NBCUniversal launched a new version of Radius that syncs with Under Armour's new app, called UA Record.

It's likely that Radius will soon integrate with two other apps, Endomondo and MyFitnessPal, both of which Under Armour announced it had acquired this week.
