Actress Jessica Simpson (27) says, “Skipping my strenuous workout routine is never an option.I basically work out two hours a day five to six days a week.“Last night I got to go to the gym at 10… and I was on the treadmill for an hour.I have a white-girl bootie so to lift it a bit, I do three sets of 20 reps of squats, lunges and jump squats.They kill me, but they really work.”
