In all honesty, I think the typeface choice could be better for the brand/message you are trying to portray.
Overall, I can understand and appreciate the feminine feel/concept you are trying to create but the typeface is too elegant and overall too complicated. Your logo should be able to say "Personal Training" without you having to state it in such large subtext. There is also not much flow to it and a feeling of disconnect between the text/typeface and illustration.
• I don't find it clean and bold.
• Either the typeface or illustration should have prominence, at the moment they are both large (competing with each other) and the size relationship is not well balanced, this includes the subtext imo. If the name/ text had more prominence and connect to the illustration it might be more immediately apparent to the viewer that her company is in the business of personal training without having to state it underneath is such large text...
• To be truly unique among the competition I think you could look at reworking/revising the abstract character. Although I like the first character design (purple) the best out of the 3.
1. A logo must be describable.
2. A logo must be memorable.
3. A logo must be effective without colour.
4. A logo must be scalable i.e. effective when just an inch in size
Ask yourself if your logo meets the above criteria? Is it going to be clear, concise and legible at the size of an inch on a letter head, business card, pen, hat, etc. Very unlikely, especially with the font/typeface being so light.
I would likely suggest that you consider going back to the drawing/sketch board...keep the intended feminine or elegant feel to it but try to work on the points I have stated above and before doing so perhaps these links can be of some additional benefit:
