Thank you!

Had to search for this one, being a bit of a couch potato myself:-)

Another option...

Women with moxie (but this is slang). Suerte ;)

http://www.thefreedictionary.com/spunky

mox•ie (m k s )
n. Slang
1. The ability to face difficulty with spirit and courage.
2. Aggressive energy; initiative: "His prose has moxie, though it rushes and stumbles from a pent-up surge" (Patricia Hampl).
3. Skill; know-how.

Adj. 1. spunky - showing courage; "the champion is faced with a feisty challenger"
feisty, plucky
spirited - displaying animation, vigor, or liveliness

2. spunky - willing to face danger
game, gritty, mettlesome, spirited, gamey, gamy
brave, courageous - possessing or displaying courage; able to face and deal with danger or fear without flinching; "Familiarity with danger makes a brave man braver but less daring"- Herman Melville; "a frank courageous heart...triumphed over pain"- William Wordsworth; "set a courageous example by leading them safely into and out of enemy-held territory"

This might be a good term to consider.

Celebrating The Nigerian Political Amazons
It’s also pertinent to state here that the travails of the Nigerian Amazons, as far as political struggles are concerned, have not been an isolated case. All over the world, the fundamental attitude of people to democracy has always, at best, been misogynistic.

For instance and ironically, the United States of America is acknowledged to be the bastion of democracy, freedom and civil rights. Yet, in the year 2005 of the 21st century, there are many Americans who still cringe at the thought of a woman president. Whereas, in some Third world nations such as Sri Lanka, Israel, India, Philippines and even Liberia, women have aspired to and held the highest positions in their respective lands.
