Little bodybuilders train every day and show defined muscles.

Claudiu and Giuliano Stroe are two Romanian boys, seven and nine years old, respectively, who devote two hours daily to an exercise routine that would make any sedentary adult jealous. Surprisingly, both boys gained strong, defined muscles - which earned them the nickname "Hercules."

Coming from a family of bodybuilders, the boys train to pursue their parents' careers. Iulian Stroe, 35, accompanies her children's training every morning and is determined to make them famous.

Claudiu (below) and Giuliano (above) have been doing stunts and lifting a few years. Even Giuliano has already broken a record for his incredible performance. Claudiu wanted to follow in his brother's footsteps and began training at just 18 months. The brothers' exercise routine includes doing pushups and lifting 4kg weights to define the chest and biceps.

There is no doubt that boys 'performance is enviable, but parents' attitude divides opinions since such an intense routine can be considered harmful to children. Ileana, the boys' mother, defends the trainings: "They have a natural ability for this, nothing is forced, that's what God wanted for them."

Check out a video taken from Giuliano Stroe's official channel and impress yourself with the skill and strength of the Romanian brothers. And then be sure to record your opinion in the comments.
