Black Line Athletic Strength Arvostelua 

Fantastic personal trainer very knowledgeable and always very supportive and most importantly you can have good laugh with him.

Fantastic trainer with good knowledge that will help you achieve your goals. Solid app as well to help you keep track of your progress. Worth every penny.

I've just completed two months of personal training with kai, and I couldn't be happier with the results and experience.

From day one, he created a structured programme that focused on both strength training and conditioning, helping me build confidence, improve my fitness, and push beyond what I thought I was capable of. His knowledge, encouragement, and attention to technique made every session productive and enjoyable.

Kai is professional, motivating, and genuinely invested in helping his clients achieve their goals. I would highly recommend him to anyone looking to improve their strength, fitness, and overall health.

Thank you for all your support and guidance over the past two months!

Kai is very knowledgeable, has an excellent attitude with hard working approach and I would whole-heartedly recommend him as a coach for strength training.

I have been working with Kai for 3 months now. I approached him with a number of goals in mind, build core body strength, rehab to a calf muscle that wasn’t working correctly after an injury and to lose fat. Kai sat with me to tailor a programme. My progress has been outstanding, yes you need to put the effort in and yes Lai will push you every session to move you a step closer to your goals. He has advised on nutrition and he continues to adjust my programme to suit the changes in my performance. This keeps things interesting and varied. If you want a PT that is going to focus on you, your results and push to achieve these, this is the right place for you

I have recently started pt with Kai and have found him to be a pleasant and supportive to me. He pushes me into believing I can lift weights and show me how to use machines in the gym. And explains why and what the exercise equipment does to improve my overall strength. Kai is very good as a PT and would highly recommend him to anyone looking for a good pt.

I have been with Kai since the start of the year and I cannot recommend him highly enough. He is the best sort of trainer in that he gets the best out of you. He knows his stuff and I feel confident lifting the weights he tells me I can. He is firm, you have to put the effort in, but always encouraging and he pushes without bullying. I am looking forward to the rest of the year with him.

I’ve been working with Kai for 6–7 months, and he’s been transformative for me. I was dealing with perimenopausal symptoms—weight gain, high cortisol, brain fog, and low energy—but his guidance, training, and encouragement made a real difference. He’s helped rebuild my confidence, and I truly appreciate his evidence-based and explanatory approach. I genuinely enjoy working out now.

Not being in my comfort zone was not an issue which I thought would be . I was welcomed and enjoyed my experiences.
Long may it continue. It's TOUGH LOVE ❤️

I have been working with Kai since having a really bad time losing my husband , put on weight no motivation and my posture causing pain. Kai talked me through what we would do , the exercises , weights and using the correct machines. I have lost weight , my muscles which I didn’t know I had ! Stronger . Kai not only built up my fitness but gave me confidence to know I could do it which 100% has made me fitter feel stronger and walk tall as my posture has improved . I can’t thank Kai enough he is strict but fair !.

I have worked with Kai for 6 months. I never considered I could be confidently doing deadlifts and back squats in my late 40's as it was all new to me. Kai took the time to understand my strengths and what to focus on to make improvemts. After an injury sustained while on holiday Kai adapted his approach and patiently worked with me until we both agreed I was ready to get back to a full strength programme. He is honest about what I need to change to get the results I want which I think is great. I can see my strength improving and feel more confident going to the gym.

I started PT sessions with Kai late last year. He keeps me motivated to go to the gym 3 times a week with well thought out, constructive planned gym sessions and nutrition plan, working towards my long term goals of benefiting my future health. He is kind and funny, but also makes me work hard and to the best of my ability and pushing me past my limits whereas I wouldn't without his support. 100/10, I highly reccomend Kai.

Kai is awesome, even though he is stricked, doesnt let you slack much at all , which I tried to do alot lol , he is fun , understanding and gets you where you want to be . that is what I needed, I started doing pt sessions with Kai as I seen big results on my friend . And With in 3 weeks i could see good results on myself . I wouldn’t go to anyone else thanks kai :) I really enjoyed working with him and fully enjoyed the plan he set up for me to do .. x

I’ve been training with Kai for 5 months & can see an overall improvement to my physical strength & fitness. I have been a gym user for many years but felt I needed to be taken out of my comfort zone so approached Kai for help. I was reluctant to use the heavier weights. With Kai’s knowledge & encouragement he has pushed me & given me more confidence in the gym. The training sessions are challenging but beneficial, I am at an age where it it’s important to maintain my strength to protect my general well being.

After a number of years balancing work and a young family, I recently decided to get back into strength and fitness. Joining Kai’s strength and hypertrophy program has been one of the best decisions I have made. In a short space of time, I have seen significant improvements in both my overall strength and body composition.

Kai pushes you hard during sessions, but it is always done with purpose and encouragement. He is incredibly knowledgeable, not just when it comes to strength training and technique, but also on the nutrition side of things, which has made a huge difference to my results. The sessions are tough, but Kai’s personable and motivating approach keeps them enjoyable.
One thing I have really appreciated is how he has built a supportive environment. He paired me with a gym buddy who has similar goals, and the small group session on weekends adds a great social element. It has been motivating and a nice way to meet new people while still working hard.

I have also had an ongoing issue with weakness in my right calf that has affected my leg strength overall. Kai has taken the time to properly assess the issue and adapt my leg sessions to help target and improve it. Although it is only a few months in, I am already starting to see noticeable progress.

I am really pleased with how things are going and would highly recommend Kai to anyone looking to improve their strength, fitness, and overall health. Thanks, Kai!

I have been working with Kai (Black Line Athletic Strength) for 3 months. I had never even thought of working with a trainer before, mostly because I thought I was doing well on my own! But I now realise and I was stuck in a non productive rutt and routine! I have progressed massively in this time and I am really enjoying it to, it’s keeping me alert and excited for each session, there’s no chance for boredom or getting caught routine!! I can feel the health benefits to, I’m eating better with more thought to food quality with use of the app. Plus I’m sleeping more soundly and longer to. This all followed a simple friendly chat in the gym, now, although the sessions are tough, we have a bit of banter and a laugh together, whilst making use of Kai’s vast knowledge of health, fitness and training techniques. I highly recommend this to anyone at any level.

I approached Kai due to my need to improve my health, stamina and strength after 20 years of very little exercise. He is professional, clear and informative. He has created a perfect health and fitness program for me to follow and works with me as I lose weight, gain muscle and become more healthy.

Since joining I have made huge progress thanks to Kai’s guidance. I had always shied away from the downstairs area of the gym with free weights and concentrated on cardio. To be honest if I had done a barbell squat before I’d have probably just injured myself. Since joining Black Line I have gained confidence, strength, developed consistency and I enjoy the gym and seeing progress. Kai pushes me, mixes things up and keeps it interesting, as well as picking up when my form needs improvement. If you want to move on to achieve more at the gym or just need guidance Black Line Athletic Strength will help you achieve your goals.

The amount of benefit and growth I have achieved from working with Kai cannot be understated. I thought I was doing fine on my own until I started working with him, he really levelled up my fitness!

Only just met Kai and had a couple of assesment sessions and one working session after signing up which I was happy to after Kai appeared very knowledgeable in his field and shows understanding of individual needs..

Im very much looking forward to coaching sessions and the improvements to my physical wellbeing..
