Get Kristen Fit


Kristen Collinson (Leontie)

Motivator/ Trainer/ Instructor/ Coach

Hi!  I’m Kristen, the face behind the GetKristenFit brand, which I officially launched in April of 2014.   My whole life I have been an avid athlete (track, soccer, distance running) and a fitness enthusiast. In 2009,  I received my Bachelor’s degree in Health Science from Northeastern University and in the years following I gained experience and expertise by working  full time as a personal & small group trainer, and group fitness instructor.

The health and fitness industry is  always evolving and I work hard to stay educated and approach my work in fitness with the mentality that there is more than one way of doing things.  There are many methods and systems that work and that are safe and I truly believe that the best trainers have an open mind and tailor their programs to the specific needs of the client(s)  or audience at hand.

      I take extreme pride in the pact that I have a thorough  understanding of anatomy and physiology and the science that determines how the human body works, how it responds and adapts to stimuli, and how to design programming to yield specific results for clients. 

The best recipe for success when it comes to your health and fitness is to find something that is challenging yet enjoyable and maintainable long term.   GetKristenFit is a lifestyle that incorporates the things your body needs to function optimally, (purposeful exercise & 80-90% clean nutrition) with the things that make you feel happy (less functional exercise & 10-20% happy food/bev).   

       My motivation style is: NO EXCUSES.   I myself have always been internally motivated, especially when it comes to fitness and performance.   There is a plan for everyone, there are modifications for everyone, there is a way for everyone to feel and look their best but you have to be willing to put your excuses behind and  GO FOR IT!!!!!

I will be your motivator, your cheerleader,  and your drill sergeant when you need it ……. because  at the end of the day I see the potential and desire in everyone and it is my mission to bring out  the best version of you!!!!!!!
