Overflow Issue

Howdy,

Re: https://jencampbellyoga.com

When this site is viewed on an iPhone the viewport is off; meaning if you press and hold on the page and move side to side there is white space showing (compared to artbees.net for example, which does not have white space on the sides when viewed on an iPhone and move your finger side to side).

See images below.

I tired this CSS but it did not resolve the issue:
body {overflow-x: hidden;}

Please advise.

Thanks in advance,
Casper
