‘Izaak has not only helped get me into a proper exercise and nutritional routine that has shown results, but has actually made me enjoy doing it! I look forward to our sessions, always feel pushed and my improvements celebrated, and have made amazing advances in both losing weight (9kg down) and building strength. I could not recommend Izaak enough to anyone who is new to exercising/weight training and looking for that extra guidance and support.’

I’ve been training with Izaak for a couple of years now and I can’t recommend him highly enough. We train twice a week and alongside a personal nutrition plan he provides constant guidance. The results we’ve achieved are far more than anything I anticipated at the start of our partnership. Izaak is supportive and motivating but does not let me get away with slacking or putting in low effort! If you want a personal trainer who will get you results along with being a really genuine, nice person, Izaak is your man!

I can't recommend Zak enough! He took the time to understand my goals and created a personalised plan that was both challenging and enjoyable. His knowledge, motivation, and support allowed me to make lots of progress in a short period of time, and after 15 years away from the gym, I have a newfound confidence in my own ability. If you’re looking for a trainer who truly cares about your progress and pushes you to be your best, speak to Zak.

‘Has helped me work on my calisthenics movements and progressions. I highly recommend Izaak.’
-Shay
‘I decided to get a personal trainer to help me build functional strength, without getting injured. I wanted to be sure I was using the weights correctly and doing the most effective routine for my limited time. Despite having been exercising for decades, I was still doing a lot wrong. Izaak has been amazing. He has fixed my bad habits, maximised my workout times and ensured I stay fit and healthy while I work on my goals. Thanks Izaak, you are a star!’
-Albert
‘I had Izaak as a PT a year or so ago, and honestly couldn't recommend him enough. I gave him such little time to get me in shape before my impending holiday, and he gave me all his effort. Down to earth guy that doesn't make you feel like you're out of place, super helpful with tips outside of the gym too and was always on hand when I had any questions!’
-Jack
‘Collaborating with Izaak as my personal coach was extremely beneficial and encouraging. He demonstrated straightforward workout techniques, and then I took the initiative to explore further. I would highly recommend you to others because you possess the right mindset, presence, and a supportive, determined character.’
-Chitra
‘I had never had any PT before but Izaak listened to what I needed and my concerns with post spinal rehab. He taught me how to move with weights and to push myself bit by bit. I now have very valuable training techniques that I use most days to stay fit and most importantly, pain free. He’s a good’n and I would highly recommend his training support.’
-Stephen
I have taken personal training sessions from many trainers, but I recently found a fabulous trainer, Izaak, and have been training with him ever since. I have set clear fat-loss goals for myself, and I’m currently on that journey. So far, he has been extremely motivating and supportive.
He is very strict during sessions, which helps me stay disciplined and focused on my goals. He also actively follows up on calorie intake, exercises, and overall progress — not only during sessions but outside of them as well.
I’ll definitely share more reviews as time goes on, but based on my experience so far, I highly recommend him!
-Sasikala
‘I've been training with my personal trainer since October 2025, and the progress I've made in a relatively short time has been amazing compared to the years I spent going to the gym on my own and just doing classes.
My main goal has been building stronger legs, and every session is tailored to suit my needs and ability. The workouts are always progressive, challenging in the right way, and adapted as I improve.
He's knowledgeable and observant, and great at what he does. I'm always encouraged to give it my all and my results speak for themselves. I’d highly recommend him to anyone looking for a trainer who really listens and helps you achieve your goals.’
-Sara
‘Like most people who join a gym I didn't really have a clue what I was doing, over a couple of years and alot of Google I sort of got things in some sort of shape.
But something was missing, so after chatting to a couple of PTs is signed up with Izaak.
We want through what I had been doing and I had the basics right but Izaak started to tweet things and.... well what a difference.
I went from "going to the gym" to actually training, with results.
I have been training with Izaak for a few years now and can honestly say it's the best thing I have done.
He listens, understands my goals and works with me to try and achieve them.
I would highly recommend anyone to take on a PT but especially Izaak…’

“Izaak is a brilliant personal trainer - I have been working with him for nearly 2 years so far, and I always really enjoy our sessions (even when they are hard). He is thoughtful and creative in working around my various injuries and weaknesses. His online tool and diet plan really kick-started my weight loss journey, and he is always super helpful and supportive both in and outside the gym.”

“Izaak is really considerate as a personal trainer, it's not something I'd have expressly looked for but now I wouldn't do without it. From day one I had to be the client that said "I won't run on a treadmill, I won't do pushups, i have bad lower back problems, my shoulder is currently injured, etc..." I hadn't exercised routinely in almost 10 years and I was in truly dreadful shape and roughly 153kg or there abouts. It's been about 6 months since then and I'm currently 140kg which is around 2 stone lost. I'm in much better condition, my lower back problems have gone, and my strength has really increased a lot. I'm still not going into the gym as often as I should, except for my weekly PT appointment with Izaak. But that's been enough to see huge improvements all round. Some of the sessions that stick out in my mind are our PB beating sessions, the ones where we broke 100kg lifts, and the one where we went through a bunch of shoulder rehab exercises to work on fixing my shoulder.”

“After a few years of going to The Gym Reading West, I signed up with Izaak to answer a fundamental question..."what am I doing wrong?" The answer came back "not a lot". So I have spent most of 2024 working with Izaak on form, tweaking a few bit here and there, adding exercises into my routine and I'm pleased to say the results have been positive. Izaak has been a great mentor & coach who is happy to chat and help anytime, not just in one of our PT sessions. I would definitely recommend Izaak for anyone wanting to improve at the Gym.”

‘I have trained with Izaak on and off for 3 years and could not recommend him enough. On top of being extremely knowledgeable with health, food & fitness - he is friendly & approachable which makes going to the gym a lot more fun.
Most recently, I hit my goals under his training, losing about 10kg and putting on some good muscle mass. I took a few breaks over the years and went from no kids and all the time in the world to train, to having 2 kids and Izaak was always able to adjust my workouts, plans and food to fit an increasingly busy lifestyle!’
- Kevin
Izaak has been my PT for 6 months now and in that time my eating habits have become more cleaner, training has been more structured, intentional and focused. My personal eating and exercise plan compiled by Izaak has been tailored to my needs of improving my exercise, loosing weight and building strength. I am particularly grateful for his patient when I complain and don’t meet the targets set, but he gently encourages me to keep going while holding me accountable and pushing me to do better. Excellent coach
-Jariatu
‘I trained with Zak for over a year, starting initially as a complete beginner to the gym. Zak made me feel very welcome and helped me build confidence, teaching me how to use equipment and explaining why we were doing certain exercises. Our focus was mainly building strength, especially in my knees as they are hypermobile and I noticed significant improvement within a few months. Zak also tailored my training when I was pregnant, allowing me to train right up until the end of my pregnancy which put me in a great position for postpartum recovery. I would recommend Zak to anyone looking for a friendly and knowledgeable PT.’
-Grace
‘My wife and I have been training with Izaak for the past few months, and he’s been fantastic to work with. He’s supportive, dedicated, punctual, and genuinely committed to helping us reach our goals.
He closely tracks our workouts and progress, gives practical diet guidance, and regularly follows up on calorie intake and training. He’s also very flexible with scheduling, which has really helped with my wife’s changing work hours.
What stands out most is his commitment — even during holidays, he checks in on our gym sessions and progress, which shows how responsible and dedicated he is.
We’re very happy with our progress and would highly recommend Izaak. His session rates are reasonable, and he also offers discounts for bulk bookings.’
Thanks, Izaak, for all your support!’
— Srinivas‘When I first started out in the gym I wanted some guidance on workouts and creating a routine. Izaak was very helpful and gave me the confidence to do more on my own and feel confident in what I was doing. Would recommend to anyone whether you’re just starting out or a regular gym goer!’
-Ellie
‘I’ve been going to the gym for years and was already motivated, but I wanted to get more out of my sessions with better execution, smarter adjustments, and proper technique. Working with Izaak has genuinely levelled up my training. He’s great at breaking things down visually, giving small cues that make a big difference, and helping me understand how to perform each movement properly. Really approachable, easy to ask questions, and clearly knows his stuff. Highly recommend.’
-Mark
‘I am a male of 50+ years of age and I have been working with Izaak for a couple of months and have seen good, positive results already. With a drop of 10kg and definite change to shape, strength and posture. A very friendly and knowledgable trainer who listens to your needs, being mindful of medical conditions and puts together programs that suit and benefit the achievement of your goals and targets. As well as the traditional training he is also working with me to strengthen a decades old knee issue that I have. He monitors the session closely and practices safely with his clients best interests in mind. Money well spent in my opinion and I would recommend to all. Keep up the good work.’
- Dave
‘I've been working with izaac since november and have lost over 2 stone and more importantly kept it off.
His plans are realistic, easy to follow and have really worked. Highly recommend.’

Since I’ve started training with Izaak my lower and upper body strength have improved significantly, and mostly my confidence has increased! Izaak is very professional, but also fun to train with! He has been challenging me gradually but also always listens to my body I couldn’t recommend him more!

Izaak is a fantastic trainer with a keen eye for detail when it comes to his clients, with a fiery passion when it comes to his profession. Izaak has been training me consistently for over a year now and he always makes me feel at ease and confident to trust in his advice and training/diet plans, I’ve never felt uncomfortable or that judgment has been passed in my efforts even if they where sometimes half arsed. He always puts 100% into our sessions which usually occur late evening, even if he’s had a hectic day already he’s always dedicated, driven and ready to push on with his clients personal development. Overall I would confidently and highly recommend Izaak to any one of all ages that’s interested in being a better version of themselves with his guidance and wisdom.

‘After surgery and 6 months of drugs to treat me successfully for prostate cancer, I had no energy, aches and pains all over and had gained a lot of weight due to inactivity and eating too much and the wrong foods.
I joined a gym in February 2026 and decided to engage a personal trainer to help me on my journey to lose weight, become healthier, fitter, more toned and regain energy.
I contacted Izaak because his specialist areas are weight loss, muscle gain and strength and conditioning – He seemed to be a perfect fit for what I was looking for.
Izaak listened to my medical history, understood my goals and reassured me that he could help me after getting approval from my GP to begin what has been a very successful journey and collaboration.
I was given clear goals by Izaak which included activity targets and a detailed diet. Originally, I had 2 training sessions each week with Izaak but that quickly became 3 sessions each week because I really felt the benefit of his expert guidance on techniques, the motivation he gives me and the fact that he knows what I can do and pushes me to always do better.
After 10 weeks of training with Izaak, I have lost 8kg and feel so much healthier, fitter, have more energy and general feel better. I am also a lot happier with the shape of my body and everyone has commented on the visible changes that working with Izaak has produced. I really look forward to our training sessions.
My workouts are tracked in an app, I follow the diet sheet given to me, I visit the gym 7 days each week (doing cardio on the non-training days) and have committed to taking note of what Izaak tells me and showing up every time. The results that I have achieved speak for themselves and although I have put in the effort, I could not have done it without Izaak.
My journey is not over yet and I know that Izaak will be with me every step of the way.
I am so glad that I chose Izaak to help me to regain my health and strength because not only is he a great personal trainer who covers all areas of health and fitness, he listens and caters the training programme to each of his clients and is great fun to train with. His warm personality and sense of humour make every session fun and I whole-heartedly recommend Izaak to anyone who wants to improve their health, lose weight, gain energy and feel better in themselves and with their body.
Thank you Izaak!
