This US dad carries his six-month-old baby girl Alexa while doing pull-ups with ease.<br /><br />The adorable clip, recorded in New York on January 30, shows baby Alexa smile and swing her tiny legs. <br /><br />He said, "this is a pull up challenge - progressive resistance training (lifting increasing weight) is one of the best ways to avoid the dreaded "dad bod" which makes BABIES the perfect piece of workout equipment!<br /><br />"They gain weight and add resistance to your workout EVERYDAY!"
