20 year old fitness model Jesus shows another amazing feat of strength, as he takes on a challenge to stack a load of heavy tyres. It’s not as easy as it might look, requiring strength, co-ordination and stamina - but it's just the kind of challenge this young athlete likes taking on.

This is one impressive all-round athlete.More at www.jesusalvarez.net
