My name is Stellah Kimathi, owner of Stellar Fitness and certified personal trainer. I train both private and group sessions. My love and passion for fitness is driven by my personal experience.
After reaching what I considered my fitness rock-bottom, I made a choice to work on my body and make it the best it could be. Through research and practice I started understanding health and fitness.
But this wasn’t enough. To get to the next level I committed to becoming a personal trainer. With this certification in hand it was now time to make a profession out of what I love doing everyday. I now draw satisfaction from guiding my clients through the fitness journey. Changing people lives and seeing them develop their physical body and emotional confidence is a constant source of joy.

This is not just a profession, it’s a lifestyle. Welcome to Stellar Fitness.

Love what you do, and you'll do it well

Personal Training

Through this process I will work to customize a fitness program tailored just for you. Begining with a fitness assesment and setting a goal we will execute on the strategy to get you there.

Group Training

Friends and family can motivate us in those day when we need that little extra push. I train small groups while keeping an eye on each individuals abilities and goals.

Corporate Team Events

Science has shown exercise increases productivity. Why not keep your team healthy and productive with a short get up and go exercise session? I design short engaging team building sessions.

  • Testimonials

    When I was looking for someone to help me meet my fitness goals, I found Stella online. Even though I did not know her I decided to put myself in her hands because her demeanour on first meeting inspired trust. After almost a year, I am meeting my goals and have confirmed that I made the right choice. Stella knows her stuff, she has an excellent work ethic and is pleasant to work with as well.

    Stella is an extremely professional personal trainer and someone I would highly recommend. She is highly knowledgeable on the different muscle groups and customizes exercises for each case. I was keen on developing a better posture, increased strength, enhanced balance, and improve flexibility. Stella has done a great job. I find her extremely reliable, committed and engaging.

    Stella is a great Personal Trainer. She is honest, principled and always punctual. She takes time to assess the needs of her clients and then develops an appropriate training program accordingly. It is not a one- size-fits-all.  She will graduate the intensity of the workouts in consultation with the client so the trainee is able to achieve a stretch without developing injuries. She will also research appropriately to bring fresh thinking to  problem  solving. I would not hesitate to recommend her to any client as a personal trainer.

  • Stellah is a brilliant personal trainer whose workouts are fun, diverse and tailored to my needs and abilities. She challenges me while providing really good guidance to make sure that I carry out all exercises safely and correctly. She is always on time and very reliable and I very much enjoy working out with her. Since I started training with her twice per week in May 2017, I have noticed steady progress in my general strength levels and physical improvements in the areas I wanted to focus on. I can definitely recommend Stellah to anybody looking for a personal trainer.
