Fans Predict Bindi Irwin’s Daughter Grace Will Be ‘Wrestling a Croc in No Time’ After ‘Training’ Video With Uncle Robert

If there were a "best uncle ever" award, Robert Irwin would definitely be a nominee.

The 20-year-old animal conservationist is known for doting on his 3-year-old niece, Grace (daughter of Robert's big sister Bindi and her husband, Chandler Powell ). Now it seems the former Crikey! It's the Irwins star is preparing the little girl for a future career in wildlife wrangling.

In a clip posted to his Instagram this week, Robert gave Grace a lesson in strength training that melted the hearts of fans everywhere.

The video showed Robert leading Grace in a series of weight-lifting exercises, though the toddler used a stick instead of an actual weight.

"Set your feet...you want your back to feel stable," Robert said, showing Grace what to do with a large water weight bag.

"Core engaged and up," he continued. "One, two, three...remember what we're looking for. When that weight comes up, elbow is the hinge."

After a few repetitions, the pair was ready to move on.

"Just worked biceps, what muscle would you like to work now?" Robert asked his young niece, who chose pectorals as the next area to focus on.

When asked how many reps she wanted to do of the pectoral exercise, Grace set her goals high.

"Could we do billions and billions?" she wanted to know.

"We can do billions and billions," her uncle agreed.

"Welcome to the first entry in Grace and Robert’s fitness show. There’s some serious training happening here! 😎" Robert captioned the cute footage.
