Two Romanian brothers - aged seven and five - might be the strongest children in the world. Giuliano and Claudiu Stroe, from Galati, both started lifting weights aged just two, reports The Mirror.

Trained by their father Iulian, the pair are capable of undertaking gruelling lifting routines with ease.

Some critics have questioned whether the children are too young to undertake such a tough training regime. But videos of their training work-outs have notched up hundreds of thousands of hits online.               –TM
