Are these toddlers the strongest boys in the world? (VIDEO)

Would you ever let your toddler lift weights? One Romanian father did that–and more! The dad has been training his sons since they were two year olds, and now, Giuliano and Claudiu Stroe, ages 7 and 5, are on their way to being the world's strongest kids!

The boys show off their impressive skills in this astonishing YouTube video. In the clip, both of the boys practice lifting themselves over gymnastic bars, using just the strength of their arms. Giuliano, the older of the two, has even broken two world records for hand walking and 90-degree vertical push-ups!

It's seriously crazy to watch! These boys haven't even hit double digits yet and they have way more muscle than I do…and they're both also super adorable! Still, I have to admit, I'm kind of shocked at the rigorous training the father puts them through. It doesn't seem entirely healthy, although no one can deny that both boys are capable of remarkable acts of strength.

Watch the video and be amazed:

What do you think of the father's training? Too harsh or perfectly healthy?
