How to modify Trainer pages?

Hello there guys. I have a problem with trainer pages of my "Power club" template. I have set the trainers correctly, but, by default, each trainer page has a contact form on the right sidebar and I don't know where to set it up. I need to change fields, set the right e-mail and most of all, add a check box for the privacy which is very important! Where do I set all these things? Can I set each form the way I like or do they have to be the same for all trainers? Thanks
