Olivia’s 16 ¼ Kg Weight Loss. Massive confidence, mental health boost - transform your body and health

"I lost 16 and 1/4 kg! My physical performance has increased dramatically. Seeing the difference in my weight loss each week gave my mental health a boost. My energy levels tripled which made me feel like a new person. The recipes were tasty which made the plan easy to stick to. The level of detail and knowledge he puts into his clients is to be admired. I trust Jazz wholeheartedly and would recommend his professional weight loss services in a heartbeat."

Jessica’s Fitness Transformation – Toned body, Faster, Leaner, Healthier Back and Strong

“My happiness level has increased 200%. I now have my period back, have more energy, reduced back pain, feel stronger, fitter, faster, healthier and feel that I have a way forward that is sustainable and a lifestyle change rather than a quick win or fad. My upper body endurance has increased between 200 to 300 %. My muscle tone has increased by about 200%. Sprinting – I am now 300% faster. Jazz is very motivating.”

Pain Rehab Fitness Transformation - Muscle Mass, Upright Posture, Leaner & Toned

“The customisation of this programme was so focused that only in a few sessions I began to feel the benefits very clearly. I would recommend Jazz to anyone needing training for injury or fitness. Now I feel very stable and pain free. My strength has improved hugely. His knowledge is vast and he will make you feel very comfortable and really focus on your goals.”

Jan’s Successful Back Pain Rehab Transformation Experience

"The inconsistencies and asymmetries diminished by 85-90 per cent very quickly. Pain also diminished to a final reduction of 85-90 per cent though over a longer period. My work is better because of this. I could potentially take up a new sport for example. Jazz commitment, knowledge and care are surely unsurpassable.  I would recommend Jazz without reservation. " My work is better because of this.

Nikki's Successful ACL Tear Rehab

“My strength has increased by 200-300% whilst both the training intensity and my training volume have increased. My training endurance is also at least double. Working with a trainer who listens to your needs and goals at the start and then follows that all the way through without going off tangent was exactly what I wanted and this was delivered with 100% focus and dedication.”

Michaela M – Successful Herniated Disc Rehabilitation

“After 12 sessions I experienced over 70% reduction of pain intensity levels, at least 85% decrease in episodes of pain while exercising and performing daily tasks and over 80% reduction of lower back tension. My rehabilitation has been very successful and now I can take my spinal rotations either to my 99% potential or get at least 70% further than I was able to after the injury. Jazz really provides a tailored experience for a client and makes sure that they walk away a way better, if not best, version of themselves.”

Ramona - ACL and Meniscus Injury Rehabilitation

I started to notice improvements after the second session when the restriction from the back of the knee vanished. The limping has been eliminated. The pain at my right hip and at the back has been eliminated. I’ve never met someone so meticulous and dedicated in his field. I’m so happy with my rehabilitation progress that I just bought another package of 20 sessions.

Mrs Taryn Stanley

I noticed results very quickly, both physically and mentally which was very surprising! Not only that, Jazz made my goals his goals, and was always so incredibly enthusiastic about our training sessions! There was strong support throughout, whether it be phone calls, messages, WhatsApp or via email. At the end I was able to complete 24 push-ups in a row and I developed a very strong core. I have been training with Jazz for over a year and achieved more than I thought possible. I cannot recommend him enough to anyone looking for the best personal trainer in London!

Franco V

I have one herniated lumbar disc and one herniated thoracic disc. My herniated disc rehabilitation has been very successful. I’ve had no flare-ups since training with Jazz. I have no more dullness or low level of constant pain on my back. I can move freely without thinking about movement. When I started training with Jazz I couldn’t do more than 3 chin ups at a time. I can now complete up to 10 in one go. My record to date is 12 chin ups in one go. That’s more than a 300% increase in strength in just two months! I can play with my son without fear of injuring myself.
