Build/Design Template for Shopify Website

Hello my name is Blake C. Burum! Hope you are enjoying your day. I have a Shopify online store called www.ztreads.com. The sites goal is to provide a wide range of cardio equipment selection from treadmills, ellipticals, and exercise bikes. The targeted audience is individuals with joint problems, obesity issues, and any other medical issue that can be helped with cardio. I used a theme for the shopify store provided by saleshunter. I have attached a few images of what the sight currently looks like and then a few examples of other sights design and layout. Essentially I want my website to somewhat mimic the smooth and professional design of these sights. I am a big fan of the nordictrack homepage and when you select a category it has an image below the navigation menu and above the collection name. I would love to have my website to have the same design/features.
