Nineveh 90 was inspired by Exodus 90 and includes both men and women.

"Nineveh 90 – the 90 days from January 1 to March 31 – is inspired by the excellent program – Exodus 90 – designed exclusively for men by Fr. Brian Doerr and others. Men may want to choose the even more demanding Exodus 90 […], and use it for our 90-day journey.
For our Nineveh 90 journey, which includes both men and women, we are embracing the great values of mortification, a support system, and the research in the behavioral sciences that says 90 days is about the time needed to change bad habits. We will also be using some of the tried and true supernatural elements. Namely, the Brown Scapular, 54 Day Rosary Novena, and the 33 Day Preparation for Marian Consecration."
Although it’s already begun for this year, maybe you could adapt it for a later start…?
My current life circumstances prevent me from attempting anything this rigorous, but perhaps in the future - I’m considering a major change this year which should free up the necessary time and energy. Blessings to you if you decide to do this or something similarly demanding!
