Text size way too big on cell phone screens

Hi. I love Illdy in so many ways. But, when I open up my website on a cell phone, the text size is unreadably large. Is there any way to adjust the text size as the template responds to smaller screens? my website is www.highvaluetraining.com. Thanks!

hey there

Hope you are having a good day and thank you for your question
