New Expert Fitness Website & Podcast Needs a Cool Logo Design

SmartFitnessCoach.com

Long time fitness and medical professional, strength & conditioning specialist, and sports nutritionist starting a new website (site design after logo completed), podcast, and marketing strategy that will incorporate logo design into multiple marketing channels for promotions and product creation. This means that I plan to use the logo design on all marketing and promotional strategies, as well as on the product line of future informational products. Important to have a professional and visually appealing logo design for this brand. Looking for an innovative, cool, professional design.

Broad fitness market consisting of submarkets of weight loss/fat loss, strength training/muscle building, and some segments of the athletic training population. Age ranges of male/female prospects, approximately 30-55.

I would like to have a clean, professional look with a cool design. Thinking of having "SFC" as logo design, and then also stating "Smart Fitness Coach" probably on the right side of "SFC".
Color scheme with Blue/Grey or Dark Blue/Light Blue. The final design would need to be in Square (for the podcast that I could shrink image) and also done in rectangular image for website header. An image design may also be used, if fits the theme of Fitness/Nutrition. Another option for the image may also be an abstract, in that it doesn't necessarily have to be "fitness", but could be an "attention grabbing" abstract image that fits the cool, Smart Fitness Coach brand. Simple abstract image, if that is used.
Would like final image to contain one with tag line and one without tag line.
Tag line "Exercise, Nutrition, and Mindset for Smart Living".
I will provide feedback as designs come in, but hope this provides a good baseline for what I am looking for.
Clean, simple, cool design and powerful fonts. Visually appealing, professional.
