Hello Kyle,
We have solved lz_fitness link issue and also sent an updated theme on [email protected], you may please download updated theme and use it.

* When I set the Header to sticky, it works but cuts the slider image in half. Should I add padding somewhere in the CSS?
–> kindly send us your wordpress website login details(including website url, username & passward) on [email protected], we will check it and setup the issue in your theme.

Thank you.
