Another drop of fuel in the Apple iWatch fire.

9to5Mac reports sources familiar with the matter say Apple is teaming up with professional athletes to test the iWatch "in intenest training environments."

Health, one of the features Apple announced at its World Wide Developers conference, will likely communicate with the wrist-mountable device, giving users the ability to track all kinds of personal health information. 

A writer for TechnoBuffalo says despite reports the iWatch will have at least 10 different sensors, this potential partnering shows Apple's focus is mostly on fitness. "The news all but confirms that the iWatch will serve primarily as a fitness tracker."

TechCrunch says the move is a brilliant marketing technique. With the Cupertino Company looking to push between 50 million to 60 million units in the first year, an iWatch is going to need some serious street cred. Enter sports stars, stage right. 

"Sports sells gatorade, and sports sells sneakers, and sports sells clothing and hats and TV trays and bottle openers and anything that has enough surface area to hold a logo." (ViaTechCrunch)
