Talk about our kinda guy, Chris Hemsworth would rather pack on the pounds than go on a diet.<br /> <br />The actor has transformed his physique by bulking up or slimming down for a number of roles and though there are advantages and disadvantages to both, he prefers to bulk up.<br /> <br />Chris had to gain 20lbs of muscle mass for 'Thor' and then he had to lose all that, plus another 20lbs to play his character in 'Heart of the Sea'.<br /><br />Gaining weight is always fun but losing it, another story altogether. <br /> <br />
