77-year-old woman takes charge of her health with CrossFit

CrossFit can seem pretty intimidating with its rigorous workouts and strength training.

But not for this 77-year old woman. Constance Tillet used CrossFit to get her health back on track after double hip and knee replacements, a rotator cuff procedure and a multitude of other health problems.

These days Constance sounds like a trainer herself -- and a tough one at that. She gave some advice in an appearance on "CBS This Morning."

"Get up and do it. Stop with the whining," Constance Tillet said.

CBS paints a picture of what Constance's life was like before she started exercising a year ago and lost 50 pounds.

"She took insulin over four times a day for diabetes and 60 pills to treat high blood pressure, congenital heart failure and arthritis," co-host Norah O'Donnell said.

Consider this your motivation to get a workout in this weekend.
