About Osa/Reviews

Fitness and health are simply parts of Osa’s life – it’s a lifestyle. She’s originally from Sweden and has been an athlete from an early age: anything from swimming to track and field, from soccer to skiing, from floor hockey to the girls’ version of ice-hockey. In the past several years her love turned to competitive doubles beach volleyball. Osa developed a habit of an even more dedicated fitness lifestyle when she came to the US, and has since spent over 15 years helping others achieve their fitness goals in Los Angeles. Fitness By Osa, FBO, was created because of her love for helping and inspiring others to get healthier and more fit, inside – out. Osa expresses that;

“My greatest reward is seeing those I work with bloom into an overall state of well-being and seeing them realize their full potential.”   

Osa is very knowledgeable in nutrition and looks at it from a holistic aspect. She took nutrion classes in college and the research and work continues always. Many have benefitted from her approach to fitness, by gaining more confidence that spills over to other areas in life. She feels it’s  been, and is, fantastic to be able to provide one on one in home training to really focus in on the individual. She’s genuinely caring, so you’ll be in great hands when training with her! Osa is also a writer and her book “The Booty Chronicles”, with True North House Publishing, released in March 2016. She also has a published article in a health and wellness magazine, VividLife.me. Here’s the article: http://vividlife.me/ultimate/34063/the-power-of-focus/

Osa’s continued desire for, and dedication to, her own fitness lifestyle led her into the modeling world as well, where she’s still active at the age of 42.Those jobs, she makes sure don’t interfere with the training of her clients. She has been recognized for having a very fit and muscular physique, while still maintaining lots of feminine curves. She’s come to have a trademark too, and that’s her butt, which has been getting quite a bit of attention (hence the book title) 😉 Though she loves to train all kinds of clients, she’s got a special place in her heart to motivate, inspire and help women realize their full power and potential. To help them feeling fit, fabulous and empowered, no matter what age. She’s excited to start a movement, empowering young girls, which has been in her heart for many years!


“I worked with Osa for three months while visiting Los Angeles and she transformed my body. We had no gym and worked only with the equipment she brought to the house in a gym bag. Osa is extremely knowledgable and careful in her workouts. There was no chance of injury which was important to me. She was always on time, cheerful and inspirational. The hour together always passed quickly. I strongly recommend her as a trainer and coach.”
