Personal Trainer, Mat Pilates Instructor, and Pre and Postnatal Exercise Expert. 


As a professional fitness trainer my passion is guiding people towards a healthier lifestyle. Every body is unique and each with its own strengths and limitations. My method is to build a custom plan based on your current health and fitness goals and create a friendly and positive environment in which to train. The intention is not only to transform your body but to influence you in making more mindful decisions when it comes to your health and lifestyle. I am proud to have helped many women with their journeys to regain the pre-pregnancy fitness, lose weight, reduce their back pain through pilates, improve posture, and complete sporting achievements such as their first 5k or half marathon race, to name a few. Added benefits have included seeing women become more energised with improved sleep and  more confidence as they adopt a healthier and more active lifestyle.

ABOUT: Inner_about


I previously worked in London as a lawyer for over 10 years before following my passion for healthy living and fitness and becoming a certified personal trainer and pilates instructor. I trained and qualified in London and continue to gain qualifications and build upon my expertise every year. I specialise in pre and post natal exercise and am also qualified in nutrition and GP referral exercise which allows me to train individuals recovering from a range of conditions including surgery, strokes, back injuries, those with asthma, high blood pressure, diabetes and IT band syndrome to name a few. I am a qualified triathlon coach and apply this to provide specialist triathlon strength training sessions to athletes. 


Donna O'Shea Fitness was set up in early 2013 and its reputation continues to grow as one of the leading fitness providers in Singapore for pre and post natal fitness and pilates.


When I am not working I am busy buying more books than I will ever read, running in MacRitchie and running after my little boys : )
