Create a capturing logo for an online fitness business

A Beginners Guide to Fitness

I want to launch a website offering coaching for beginners to fitness
and exercise. This could be weightlifting, crossfit, any sports and
also nutrition. All visitors will get the opportunity to sign up for
my free 6 weeks beginners program. This will be a newsletter, where
they will get daily workouts and tips. The website will also have a
page where i post articles about training, a page where I sell my
e-books and online coaching, and also an online video library. My
target audience will be everyone who is new to fitness and exercise.
This will mainly be younger people (age 16-20), both boys and girls.
But there will also be some older persons (older than 20). We would
like to promote a healthy, balanced and sustainable approach to
fitness.
I want my logo to be modern, so that I don't have to change it the
next 10 years. I also want it to reflect that this is mainly an
online
business. The logo doesn’t necessarily have to include the whole
business name. I will be open for suggestions. Have not decided if I
want to incorporate the "A" in the name, and just go for "Beginners
guide to fitness". I know the name is a bit long and maybe difficult
to incorporate in the logo, so what about a focusing on what fitness
could be, or mean for someone? Could we make a image or a shape of
someone running, someone deadlifting a barbell, someone hanging from
a
bar or some rings or other kinds of gymnastics or someone holding the
barbell over their head as in a snatch? What about something that
incorporates gymnastics, weightlifting and powerlifting? The fitness
concept is much
broader then just lifting barbells....

Website design and e-book design needs to done after I have found a logo I like.
