Seeking insight from Woman that are into Fitness & Wellness

My Name is Jim and I am a Freelance Health, Fitness & Wellness writer that does articles mostly for blogs & ebooks.

I am currently trying to research a new topic, and I was hoping for some insight from the folks on this discussion board.

My target audience are Women in their 30's - 40's, that are into health and Wellness (Fitness, Nutrition & Alternative Methods).

I like to know what issues women are motivated to solve and having difficult time finding solutions to:

Some questions I am looking to answer:
1) What are women looking high and low for?
2) What information Woman cannot get and how badly do you want it answered
3) What is the biggest challenge you are facing in your fitness routine or in reaching goals
4) How hard do they work to solve this problem?

These are just some core questions, but if you have any additional items to add, feel free to do so.....

Thank you in advance for the information
