I love leg day! To me, it's the best training day of the week. I literally run to the gym on leg days to warm up and get my blood flowing before I hit the weights. I train legs twice per week, hard and heavy. My favorite method for training legs uses supersets, so that's what I have in store for you today. 
Many women think that if they train their legs with heavy weight, they will get too big. Some ladies are afraid that hard training will make them look less feminine, which simply isn't true. Heavy lifting increases your metabolism, which allows you to stay in good shape much easier than women who never lift. Busting your butt won't make you a man; it will make you look healthy, fit, hot, and sexy! Lifting will also give you more confidence, I promise. 

LEG PRESS
As a WBFF competitor, I have to sport shapely legs that showcase a certain amount of definition and feathering. One criterion in the fitness category is to show nice definition in your hamstrings, glutes, and, of course, calves. 
To accomplish this, I train my legs regularly but give them ample time to recover between workouts. Muscles grow when you rest, and it is a big mistake to exhaust yourself by doing each body part every day. Be sure to rest 2-3 days between your legs workouts, especially if you train them heavy.
