Though many stars help popularize diet fads and the latest anti-aging procedures, Cindy Crawford evidently prefers to do things the old fashioned way. On Wednesday, the 50-year-old mother of two took to Instagram to prove that, for her, staying in shape is all about breaking a sweat.

“Hitting the treadmill hard today with @SarahPerla1,” she captioned the below ‘gram of herself making major progress on the treadmill in what we presume to be her at-home gym, with her go-to trainer, Sarah Hagaman. Don’t think Crawford forgot to throw on some killer workout gear for the cardio session. She sported a purple tank with black tights and colorful sneakers.

This isn’t the first time we’ve seen the supermodel work hard for her body. Hagaman has shared images of the brunette taking on a beachside run in a similar getup.

Keep on keepin’ on, Cindy!
