I redesigned your store page to make your products clearer, including the specs. I chose a font for headers that more closely resembles your logo and simplified to one additional font that is easy to read.

Customers can purchase directly from this page, or click on an item to get more info. I suggest adding photos of people using the bands to further illustrate the difference in sizes. Also, updating the product images to show the colors available. For instance, the small bands show purple, which isn’t an option to select.

I added a red menu bar to the main store page and each product page to help users navigate between sections.

I also suggest including photos of people using the grip tool for people (including me) that are unfamiliar with the tool.

I placed the safety and warranty information in an accordion box to help keep the text from becoming overwhelming.

Lastly, I updated the footer with contact information and icons to advertise that your products are made in the USA, latex free and 100% recyclable.
