This is going to be great forZach Wilson.

At Miami Swim Week, Austin showed off her amazing figure while walking down the runway in a bikini.

They are the first mother and daughter to rock the runway together at an event.

Austin became a household name after making more than 50 fitness tapes, and her daughter followed in her footsteps with her own health focused app.

Austin said it was a once in a lifetime moment.

My daughter and I walked in the runway show. My daughter and I are in a bikini. It's pure joy.

It was a cute moment to hug my mom on the runway. We passed each other and said we loved each other.

I felt so grateful of the opportunities in my life this past weekend.

I guess those fitness videos work.
