The "Material Girls" actress and her ex were spotted at Rise Nation gym in LA, reported AceShowbiz.
Duff, 29, opted for a simple scoop neck black top with a pair of leggings, while Walsh sported a sleeveless black T- shirt, grey athletic shorts and white sneakers.
Duff also took to Instagram to share a group photo from the day. It also featured her former boyfriend.
"There was no option but to turn this photo black and white. I was literally purple this climb was so hard and it was so hot! Charity climb for the land that I love #houston @risenation," she captioned the black-and-white snap.
