Today, I was her

Today I was "her" at the gym.
You know.
The one who sweats and stinks.
You can see her clammy skin.
The beads of sweat on her bare shoulders,
Taunting you on your treadmill,
Saying "You should be working harder--
Like her."

Today I was her.
In sweat, if not in body or in glances.
Inside, I was a lithe ironwoman
with 10% bodyfat,
racing in the wind,
perfect stride,
hair billowing freely behind me,
muscles glistening.
