Ex-Australian beach sprinter and fitness trainer Katie Williams takes on different diet and lifestyle challenges for 2 weeks at a time, to see if they help her think, move or feel better.

She speaks with experts to get the advice and support she needs before each challenge and afterwards she checks back in to see if she's better for having done the challenge.

Better For It - now available at LiSTNR.
