AT&T posts new teaser, likely for the Galaxy S6 active

AT&T has posted a teaser that points to the imminent arrival of the Samsung Galaxy S6 active. Calling it "the only thing missing from your workout," the teaser doesn't explicitly show the device to which it refers. However it's very likely that it is indeed the rugged variant of the standard Galaxy S6.

From AT&T:

Previous reports have indicated that the S6 active would debut first on AT&T. The device is also said to have similar specs to the standard S6, though with a 3500mAh battery, rather than the S6's 2550mAh unit.
