Jessica Simpson’s Latest Cutoff Shorts Moment Will Make You Do Squats at Your Desk (PHOTO)

Will we ever tire of writing about Jessica Simpson‘s legs? Probably not, because each time she steps out in a mini or a pair of cutoffs, she appears to be even more muscular and toned each day.

Simpson selected a pair of her favorite denim Daisy Dukes (short enough to expose her pockets, of course — the lady loves a throwback look) plus a black tank and wedges for date night with husband Eric Johnson Thursday (photo above) and her stems have never looked more toned.

Her secret? Circuit training. Lots of it. “We alternate exercises every third day,” Teri Ann Krefting, Simpson’s trainer who works for Harley Pasternak, told PEOPLE. “So we’ll do squats and lunges one day for quadriceps, deadlifts or glute raises to tighten the butt and hamstrings the next day, and then plie squats, which are good for inner thighs.”
