Mom goes to the bathroom for 45 seconds and returns to find her toddler on a treadmill

If you've been around little kids for even a second, you know their greatest threat is often themselves. 

Madeline Valdivia was reminded of that yesterday, when she left her 1-year-old, Samuel, on his own for under a minute just to use the bathroom, and came back to this near catastrophe.

In the video, Samuel is crying as he runs on the family treadmill at a pace most adults would envy, hanging onto the bars for dear life.

As the treadmill slows down, Samuel's wailing stops and a small grin develops as he begins reaching to start it back up again.

Valdivia describes her son as fearless and said he's always doing "silly, crazy things like this".

"He likes to go on the walker and press start. He can’t reach the speed settings yet," Valdivia said. "The reason it was going fast is because my little brother was just on it and left it in a different setting so it automatically switched speeds after a minute of him clicking start!"

Valdivia's tweet has since gone viral with nearly 300,000 likes, and some of the reactions are golden.

Others are calling for this fitness icon to appear on The Ellen Show.

"I guess I could say his special talent for him to be on the show is speed walking or baby running," Valdivia said.

Who knows — we may be seeing more of Samuel's shenanigans in the future.
