Giuliano Stroe aged 6 and his brother Claudiu, 4, show off their muscles and tricks at their home gym. The two brothers ,aged just 6 and 4, are trained intensively for hours each day by their father Iulian, 35. He is determined to turn his boys into stars, known for their displays of strength and agility- doing tricks that many adult athletes would find impossible. Showing off his six pack and muscular arms, Giuliano is an Internet hit on sites like youtube, where his videos have over six million views. He claims the boys love working out saying, "you can't force a child to train if he doesn't like it?"

Giuliano Stroewhen he was a 5 year old he was in the Guinness Book of World Records for fastest 10m hand walking. Giuliano has been working out since age 2 and is now a bodybuilder.

These kids started theri work out at two years old, and follow their father, Lulian's, weight routine for two hours each morning. The two are incredibly strong, with Giuliano holding the world record for 90-degree vertical push-ups and the human flag.

Whether it's normal or healthy for their father to be putting them through the routines is another debate entirely, especially when he apparently admits he hopes his sons become stars.

But it's still amazing to marvel at what they're capable of accomplishing.
