As others have mentioned, making your profile page look more attractive and being a better trainer are two different things. Here are my comments on your profile page.
1) In the “about me” section, there is an option to write a paragraph about yourself. You might take advantage of that space to write about your training style, your specialties if any, and the radius within which you travel.
2) You might consider having a photo with a lighter background, and perhaps smiling.
3) As already mentioned, if you have any clients who are willing to give you testimonials, that will also help potential clients by reading what it is about you that they appreciate.
