Kate Lomas
As a busy health care practitioner who travels a lot I was finding it challenging to be consistent with my personal healthcare. Working with Oscar really helped me develop a consistent workout and nutrition plan that supported my health and wellness goals. No matter where I am, or how much time I have, I have learnt how to prioritize movement and dietary decisions to support my strength training. I feel stronger now in my mid-forty’s than I ever have and look forward to maintaining my strength long term. Thanks OSR!

I struggled for the past two years to lose weight that I've gained after having my son and also after having meniscus surgery. In 5 months I have lost 22 pounds and I feel great! OSR Fitness has helped me have a better relationship with food and learn about nutrition! Overall I have had such a wonderful experience. I've used personal trainers before but never had the best experience like I do with these guys.

Gosia
I came across OSR through friends while I was obsessed with running, having completed two marathons in a year but still feeling unhappy with how I looked and felt. On a whim, I decided to prep for a bikini competition and had one year to train. Oscar guided me every step of the way, teaching me about strength training, nutrition, and recovery. I stopped overtraining and shifted to smart, effective workouts. With his incredible support, I achieved more than I ever imagined. Preparing for that competition was life-changing, and Oscar was the perfect coach!

Since working with OSR Fitness, my whole lifestyle has done a complete U-turn. I used to be the guy necking 6-7 pints at the pub, but now I’ve found a new passion for working out and eating well. The best part? I’ve managed to strike a true balance. I still enjoy a few pints here and there and eating the food I love without messing up my progress. I’m happier, more confident, and wearing t-shirts proudly like never before!
