Hi Fitness Coach,
The site looks good, like what you did with it. Here are my suggestions.
1. The Pop-up Capture on the home page comes up too quickly, you may want to delay that a bit.
2. When you click on some off your tabs/pages on the top, the other pages/tabs are no longer available to click on at the top, you may want to make those available. This will make it easier for visitors to browse your entire site.
I just did an entire 5-Class Boothcamp for FREE on how to build a site to brand YOU and YOUR business, I went into alot of details on marketing and SEO in this class. You can check out the course schedule and the entire training here>
