Akzidenz Grotesk  Sugerida por donshottype 

This Fitness Water wordmark was not made by simply sloping an existing font, cutting creases in _P_ and _p_ and adding a top serif to _l_.
Here is the logo, skewed 22 degrees left, so that it is upright

Note that there is no harmony between any of the four curved corners on _o_ and _e_.

The only letter that resembles an existing font is the _r_, which is similar to the _r_ found in Akzidenz Grotesk, and various other fonts.
