Sierra taught me to believe in myself! She pushed me to my limits and encouraged me all the way, to get stronger, both physically and mentally! I highly recommend Sierra as a trainer, if you are looking for excellent results that stick!

4 weeks consistency and showing up for myself, completing your beginner build programme, pretty chuffed with the results so far, 14lbs down. It might not have been fun to take those first pics but it's a good reminder how far I've come still a way to go but on the right path!

DOWNLOADHey! I'm Sierra Flint, a mother of two & a certified personal trainer & nutrition coach!
I’ve been to both ends of the spectrum, underweight, focusing on too much cardio and too little food and constantly anxious to the other side where I gained almost 70 pounds with each pregnancy.
Not only have I been studying and applying fitness and nutrition to clients for almost a decade but I've also lived through and experienced what it takes to get the results.
I understand being a busy mom and having all the things on our plates. I’m here to lead you and show you how to create the energy, strength and confidence you deserve in a simple, effective, time efficient way that you can actually maintain over time.
We focus on simplicity that WORKS.
