Chelsey Rose


My name is CHELSEY ROSE I am from San Diego California and I am a certified health coach, a certified personal trainer, an influencer, accountability partner and a health and wellness blogger. I have been creating online fitness plans and meal plans for women all over the world for the last four years! 


In college I had an interest in psychology and behavioral sciences but I also had a love for health and fitness and didn’t know which route to take. 


Helping women achieve their health and wellness goals by understanding the psychology behind why they do what they do and helping them understand how to make healthy choices has been the perfect combination of the two.I hope to continue helping as many women as I possibly can for years to come!



Chandler Mikos


My name is Chandler Mikos and I am so excited to share with you everything I learned over these years about personal training and nutrition! 


My life began not with fitness but with the pain and frustration of being unfit and out of shape. I truly believe the help I give to change someones life is based on my own struggles with health. It’s one thing to read and study it’s another to struggle and fight for your own goals. 


I wasn’t born fit. 


That’s what I’ve tried and succeeded in doing for so many clients over these years, help them avoid all the pitfalls I made and reach their goals, I can show you that you can have an amazing life and never diet ever again! 


Night and day, I’ll be that extra arm to get you to your goals!
