Brand Name and Logo Project - Personal Trainer

Hey, I need a designer who can help with my brand name and logo design for my new Fitness / Personal Training Business. My name is Kimberley Rose, so would like KR in there. My brand will be targeting many different audiences, so something simple and bold would be perfect. Something clear, with a dumbbell or something similar, easily identifiable to the gym.
Words can also be used if you think this would look better. Open to suggestions, but have included some images as examples of the sort of thing I like!
