women get in a little trouble when they hit 25. and a LOT of trouble when they hit 30.
metabolism ain't what it used to be... they can party and pig out and never train and look skinny well into their 20s, just like guys.
However, they hit age 30, and those bad habits start to take their toll quick.
Many women age TERRIBLY from age 27 to 32. that is when they gotta start showing up to the gym or they start looking like their mothers.
