Coxswain on Rowing Team?

I'm thinking of trying out for crew my freshmen year of college in the fall. I emailed the coach and he said that I would be perfect for coxswain (I'm 4'10 and 110 pounds) and that he'd teach me everything I needed to know, so it's okay that I have no experience. It's still summer so I am gonna try to get in shape for the fall. So, does anyone know what exercises I should do in order to be in shape for the team? Specifically for the coxswain position? Thank you so much!
