  • Sesa fitness has really helped me understand my physical ability and how to push in incremental steps to help achieve my goals. It has taught me a lot about myself and my capability! Thanks Sesa Fitness!

  • I've been following an 8 week nutrition plan designed for me by Aleks from Sesa Fitness....an easy to follow plan with a variety of foods has kept me motivated and feeling satisfied after every meal. I can already feel the weight coming off - thanks Sesa Fitness!!

  • My name is Jacob and I have a Down syndrome. After just few months of training with SESA Fitness, I became articulate as my muscles were sore. I am now more confident in my strength and physique. I am not afraid anymore to show the world my body. My energy levels have increased and my health improved. My muscles have developed and I am now more knowledgeable what I put into my body.“Aleks shows me how to do the training and I love it!”

  • I was never confident to do training in the gym due to my disability. Aleks understands my disability and I feel comfortable with her. I love my training with Aleks. She is a good trainer and she is explains to me how to do the exercise in a safe way. I now understand different muscle groups and what to do when I am sore. I love to do the stretches and have the exercise in my own home where I feel the most comfortable.

  • I love to train in the local park with Aleks. When I am in school I think about my training that I will have in the afternoon. I look forward to my sessions each week. I am grateful that I have NDIS funding because it gives me the opportunity to look after my health and well-being.
