This program is truely amazing as I have been trying to shed some weight but was able to do so.
Through this program which I took over 2.5 weeks with a weight loss of 4.7 kg, I was taught how to eat healthy and also choose the right food. Even though my program has ended, I continue to lose some weight gradually with the same diet.
Thank you Isaac for your encouragment during my weight loss journey. I highly recommend this program if you are looking for weight loss. A little determination goes a long way towards your weight loss!

I am truly grateful for my weight loss journey with Rejuve8 program. In just 25 days, I lost 5.7kg—and the best part is that it was achieved without replacement meals. Instead, I learned how to eat healthier, prepare clean and balanced meals, and most importantly, adopt lifestyle habits that make the results sustainable.
The program has been incredibly effective, not just for weight loss but also in helping me change the way I approach food and health. Isaac and team provided excellent support, practical advice, and constant encouragement, which made the entire process motivating and enjoyable.
I highly recommend this program to anyone looking for a realistic, supportive, and lasting way to reach their health goals. It’s not just about losing weight—it’s about gaining a healthier, happier lifestyle.

I have been training with Isaac for a few years now. I met him at a time where I was transitioning from another trainer who wanted to do some other thing and the timing was quite providential. As most of us know, it is not easy to find a trainer that fits our training needs but I find that Isaac is flexible/adaptable enough to train with almost anyone.
He knows when to push me and when to not, and similarly, he’s very attuned to injuries or pains that my body may be going through at that time and adjust the workout accordingly.
There have been compliments from my colleagues as to improvements to my physique when I train with him. Something that was never the case with my other trainers. I think it’s also because Isaac combines or complements his workouts with tips on nutrition and dietary requirements.
No complaints from me except perhaps when he keeps adding to the weights on to the rack or bar 🤣

Working with Isaac Chang has been nothing short of life-changing. From our very first session, I knew I was in the hands of a true professional—someone who doesn’t just understand fitness, but understands people. Isaac brings the perfect mix of science, strategy, and soul into every workout. He meets you exactly where you are and guides you—step by step—to where you never imagined you could be.
His knowledge is unfathomable, but what truly sets Isaac apart is his ability to motivate without intimidating, to inspire without ego, and to listen without judgment. Whether you’re an elite athlete, a total beginner, or somewhere in between, Isaac will customize your plan with surgical precision and deliver results that speak for themselves. He asked the right questions. He saw me, not just as a client, but as a person with unique goals, struggles, and potential.
From our time together, he has helped me rebuild my relationship with fitness. He taught me how to show up consistently — not with guilt, but with purpose. His coaching is a perfect balance of technical mastery and emotional intelligence. He pushes you when you need it, pulls back when your body needs recovery, and always finds a way to keep you focused, empowered, and excited about the process.
Every session is purposeful, challenging, and somehow... fun. His energy is contagious, his professionalism is unmatched, and his belief in you—especially on days you don't believe in yourself—is what makes the biggest difference.
I've gained strength, confidence, discipline, and most importantly, a new mindset around health and performance.
Whether you're a total beginner or a high-performing athlete, Isaac will meet you exactly where you are — and then take you far beyond what you thought was possible.
If you’re looking for the best, stop searching. You already know where to look.

I started training with Issac because I was feeling weak and wanted to build up my strength as age is catching up. He has been very patient, encouraging, and always adjusts the training to suit my pace and ability. I’ve already noticed improvements in my strength and confidence, and I feel more motivated to keep going. Highly recommend Issac if you’re looking for a supportive and knowledgeable trainer! 👍💪
