It is true when they say time flies when you're having fun! Lurong Living Challenges and CrossFit Arenal have truly changed my life! I will be 51 this year and I am in the best shape of my life! I am doing things that I never thought possible like racing in my first triathlon. Thank you for being the absolute best support on my amazing journey! It has been an overwhelming, incredible adventure!
This challenge will change the way you look at food, and at your health, your strength and your determination. It will make you stronger in every way.
