'Iranian Hulk' Sajad Gharibi has admitted he often struggles to sleep due to the pain he inflicts on himself by throwing power punches.
Gharibi is preparing to face 'Scariest Man on the Planet' Martyn Ford in a bumper exhibition which will be staged in the UK in April.
His 'Iranian Hulk' nickname comes from his remarkable and powerful frame weighing approximately 177k while his opponent Ford stands seven-feet tall.
