Fitbody Boot Camp About Owner

Darin and Marijeanne (Mj) Day

Hello! Our names are Darin and Marijeanne (Mj) Day and we are the owners of the new Sun Lakes Fit Body Boot Camp located in Chandler, AZ. We are very excited to announce that we will be opening August 1, 2022! Let us tell you a little about ourselves.


I am a wife, mother, grandmother, recently retired teacher, and will be the Client Coordinator for this location.

I am striving to get stronger and healthier in this next chapter of my life. As a United States Army Veteran, I have struggled for years with a back injury sustained during my time in the service so I know firsthand how challenging working out can be.

Fit Body Boot Camp doesn’t only offer personal training in a group setting – it offers life changing results in just 30 minutes per day. Once we open, I will be right there beside you working, sweating, and offering encouragement. We will all be in this together!


This may be a little repetitive, but I am a husband, father, grandfather, and sales director for UPS. I will be coaching and taking care of day-to-day operations.

My Boot Camp fitness journey only started in the last couple of years when a neighbor asked if I would like to try Fit Body Boot Camp with her. I had no idea what I was getting myself into but agreed to attend my first session a couple of days later. I was blown away by the workout and the changes I began seeing in myself over the next few months.

Being fit and staying in shape have always been a big part of my life not only for the physical aspects, but just as much for the mental ones. The self-confidence and positive attitude that goes along with being fit has a huge impact on your whole outlook on life.

Our Goal

We want to help others realize that they are not alone in their fitness journey. Almost all of us have fallen off the fitness wagon at some point in our lives, but that doesn’t mean we can’t get back on and start again – no matter what stage of life we are at. One of our main motivating factors for staying fit is our family. We recently became grandparents, and we want to do everything we can to be part of those little girl’s lives for a long-long time. We want everyone to realize that this journey is not only for yourself – it’s for your loved ones too.

We will strive to provide you the same results as other Fit Body Boot Camps have provided around the world! Our coaches will push and motivate you to be proud of your abilities every time you come in! We are so thankful to have the opportunity to do what we love, and love what we do. Fit Body Boot Camp is for all fitness levels, and we want every member to feel as though they are a part of our family. We look forward to helping you in your fitness journey. We will be right there beside you every step of the way.
