Ladies and Gentlemen: Start your stepcounters.
“12,000 Steps #HappyMonday,” Simpson, 37, wrote.
“I walk three miles a day,” she previously told PEOPLE. “Eric and I love taking the kids out for long walks in the neighborhood. And chasing them around our yard is a workout all its own!”
Simpson, who designs an athleisure line for Macy’s, said that exercising is part of her daily to-do list.
“Maintaining a healthy lifestyle is important to me, and fitness has been a priority in my life since having my kids,” she said.
Simpson gets her workouts in with celebrity trainer Harley Pasternak, and often focuses on leg movements.
“We alternate exercises every third day,” Teri Ann Krefting, a trainer who works for Harley Pasternak, told PEOPLE in 2014. “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.”
They’ll also do an hour of cardio four to five times a week.
“She walks on an incline, which helps her calves” Krefting said. “And she’s obviously genetically gifted with those legs!”
But one question still remains — is she wearing Vibram shoes on her walks like her husband?
