About Icon Training Icon Nutrition Icon Blog Icon


The KS Fitness family has many different characters with all kinds of goals, occupations and lifestyles. Everyone puts some seriously hard work into their training. Results always come with hard work and dedication, which is exactly what KSFitness is all about.

We welcome anyone - whatever your goals, needs, injuries or health issues. We love to help people "become a better version of themselvesโ€. That's the reason we do this for a living - there's nothing more satisfying than seeing clients change their lives for the better. It's great to see them enjoying life because they have so much more confidence thanks to having trained and reached their goals. Watching clients get fitter, stronger and healthier is what gets us out of bed in the morning!

There is so much more to training than people think. It can help with so many aspects of people's lives. The correct training can have an impact on blood pressure, confidence, posture, injuries, pregnancy, work life and social life. It's not just about being a bodybuilder or super athlete (although, if that's your thing, more power to you). Training has all kinds of layers to it, whatever your age. We train 18 year olds to 70 year olds with completely different goals and health issues. We work with yoga instructors, actors, music and tv producers, bankers and rugby players, to name just a few. They all have limitations to training with work, children and busy lifestyles but they find the time to get it done.

My name is Kev Selley and I'm the proud founder of KS Fitness. I've trained for over a decade and I've been a personal trainer for almost 5 years now. When I first started training, I made all the mistakes you can think of. I was falling off the Swiss ball, getting the Barbell stuck on my chest, falling off the treadmill, and executing a bad technique on everything! I had no idea what I was doing because there's so much to learn. Over time, I signed up with a personal trainer and started learning and doing things properly. I also began to gain an understanding of how to piece training and nutrition together.

My claim to fame is that I'm a former pro wrestler. Wrestling was very challenging but very enjoyable and I competed all over London, Spain, Italy and Germany. It helped me to focus on my goals. I knew then that I wanted to help other people discover the kinds of training and exercise benefits that I had found. I wanted to make a difference to people's lives. That's where my personal training journey all began and that's when the idea for KS Fitness was born.

Click on the names below to find out more about the KS Fitness family.

Team Fit Jamie Team Fit

I've been training Jamie for almost two years now, and we have certainly had a lot of fun during that time. When he first started training he was very hesitant to experiment with his workouts. Jamie stuck to the same type of plans such as running, rowing and bike machines.

Then once we got going his body gradually started to change. We introduced weight training, high intense drills, plyometrics and powerlifting. Jamie is Technically very very good with his movements and always tries his best for every session, even if he doesn't always enjoy them. ๐Ÿ˜‚

A pleasure to work with, Great guy! ๐Ÿ’ช๐Ÿฝ๐Ÿ‘๐Ÿฝ

  • BB Squat 80kg
  • Leg Press 240kg
  • DB Incline Press 22kg
  • BB Clean & Press 50kg

Iโ€™ve been training with Kev on and off for around 3 years now. I always thought running or some type of cardio would keep the weight off but after training with Kev it turns out that a mixture of cardio, weights and hiit training really does keep me trim, and on the plus side I really enjoy it! I would have never of entered the weight area prior to training with Kev, who encouraged and built my confidence up to train wherever and whenever on the gym floor!

Kev empowers and motivates me from the moment we start our sessions until the bitter end! Heโ€™s a brilliant and attentive PT who has become a friend over the years.

Team Lean Craig Team Lean

I first met Craig around 5 years ago when i was just starting out as a personal trainer at Romford Fitness First, on the very first session I could tell he needed some help with his training, and really needed some guidance with what to do.

Fast Forward 5 years and Craig is now one of my longest serving clients.

Craig has progressed unbelievably well over the years and improved on almost every aspect of training such as, Strength, Conditioning, Flexibility, Endurance and Technique. He lost weight, lost inches, built muscle, toned and shaped his body, Craig puts in the effort during training and doesnโ€™t shy away from trying new things and adding new plans to his workouts.

It's an absolute pleasure to work with Craig and see him becoming the best possible version of himself.

Well done brother. ๐Ÿ’ช๐Ÿฝ๐Ÿ‘๐Ÿฝ

I have known Kev for about 5 years. I trained regularly with him for 2.5 years and have recently gone back to him. I had never been someone who worked out and working with Kev completely changed my mindset towards fitness. Over a short time my confidence grew in the gym and I started to see massive changes to my body. I was losing weight and gaining muscle - I was in the best shape I had ever been in. None of this would have been possible without Kev. He is very personable, understanding, encouraging and accommodating. Every session I had with him was clearly well planned and designed to help me reach my goals. I took a break from training for a while and have recently gone back to Kev and it feels like no time has passed. He is extremely professional and knowledgeable - even offering advice and help when I am not in a session with him. I would highly recommend Kev to anyone who wants to make changes to their body, fitness and overall health and enjoy it while they're doing it. All around great guy and trainer!

Team Strong Keelan Team Strong

Keelan is another very long serving client of around 3 years now, and he has really improved drastically Since the day I first met him.

Keelan had quite a bad posture when we first started training together and really needed some work to push everything back, He also needed to tighten up some areas of his body, but after mixing up his programme and tweaking certain parts of his nutrition he started to gradually change.

The before and after pictures is living proof that hard work pays off and Keelan still trains with me to this day whilst also training himself, itโ€™s a part of his life now.

Itโ€™s a pleasure to work with you buddy even though you support Arsenal. ๐Ÿ˜‰๐Ÿ˜‚

  • BB Deadlift 95KG

When I had my first session with Kev, I was in the worst shape of my life. Confidence low, size but no strength and cardio wasnโ€™t a word in my vocabulary. I never intended for personal training to be a long-term commitment- maybe a session here & there to get some tips at a maximum. We identified my goals and the sessions steadily became a fixture in my diary. Weโ€™ve continued to work together on a regular basis and the improvements in both my performance and confidence has been staggering. Strength training has clearly improved, with personal bests far exceeding what I ever thought I could achieve. My cardio has undoubtedly improved, I enjoy high-rep sessions and even leg days, when previously they were a source of fear. These improvements have poured over into other areas of my life, making me more active and confident while using these strengths to improve at other sports. While Kev has some questionable opinions with regards to football (Spurs fan), I value his help when it comes to discussing diets or tweaks to my workout routine. Working a full-time job with part-time studies, finding the motivation to work out in the evening can be a struggle, which is why Iโ€™ve previously excelled with a โ€œgym-buddyโ€. Having lost that previously, that motivation would sometimes slip. Working with Kev has allowed me to keep up that motivation, drag myself in and get my workout, even when it would be easier to keep my feet up at home. Iโ€™d certainly recommend Kev, and advise anyone who is interested in getting fit or improving their performance, but is apprehensive to give him a call.

Team Lean Colin Team Lean

KS Fitness's Colin

'The 70 year old that wants more results. '

Colin is a dedicated client Iโ€™ve been training for 1 year now and he continues to improve month after month. When we first started training he had some experience with how to work the body, but just needed guidance with different types of movements and styles of training to keep his body guessing.

His strength has improved rapidly going from 25kg deadlifts to 65kg deadlifts and bench press going from 30kg to 70kg. ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ Impressive stuff really considering Colin is the tender age of 70 years old.

He looks 10 years younger, he trains 10 years younger, he is โ€˜Colin the Crusherโ€™ ๐Ÿ˜‚๐Ÿ’ช๐Ÿผ


  • 48% BODY FAT DOWN TO 34%

Personal Bests


When I started Fitness from another gym, I realised that my training had become the same tired old routines and I also wanted to try to improve certain areas such as posture, fitness and more muscle if that was possible although this is more difficult later in life.(I am 70 years old). I saw Kev in the gym training others and got to know him through one of his clients. The program that Kev has designed for me has shown, after a year, that I have improved in all areas and more than I asked for. Every session we have is different with a big variety of exercises. I am constantly learning new ways to train and enjoy every session. Its a pleasure to train as Kev is personable, knowledgeable and encouraging, and I would recommend him to anyone looking for a personal trainer.

Team Lean Esther Team Lean

KS Fitness's Esther

'The One thatโ€™s Crazy but Hardworking. ๐Ÿ’ช๐Ÿผ๐Ÿ˜‚'

Esther had a few doubts whether working with me would help her or not, she suffers from numerous menopausal symptoms and severe aggravation in the legs and hips. It affected her everyday life and was starting to really bring her down, until she did something about it.

Iโ€™ve been training Esther for around a year now and in that time we have seen significant changes to her body. Weโ€™ve straightened up her posture, improved strength around her hamstrings, back and core and most importantly changed the way she feels about herself. Esther has made significant changes month after month to her body that she is now reaping the benefits for, and itโ€™s all testament to her for wanting to make a change.

Itโ€™s a Pleasure training you BOSS. ๐Ÿ˜‚๐Ÿ˜‚

Menopause symptoms have hit me hard, my hips and legs cause me the greatest pain, sitting down or up. At my lowest point of finding no solution to my painful symptoms, an advertisement from Kev appeared on my facebook and the words x1 free session caught my eye. Iโ€™ve been in a gym before and understood the connection between wellbeing and fitness. With nothing to lose I signed up for the x1 free session and asked many questions relating to if he had trained anyone in menopause and other injuries I have.
Nearly ten months later I am nearly free of pain, for me a miracle, on many levels. The qualities Kev has shown me are: - Knows his anatomy and somatic. - The muscle function and reaction to different exercises. - Is a good listener to the clientโ€™s concerns and wishes. - Recognises when moral support is more important than the training that day. (Kev pep talked me through two very low days in my training.) - Feedback after every session to develop the next training with you. - Texts you the night before to confirm the training times. - Enjoys a good professional relationship with his client. It is a joy to go every time to train with Kev with his happy, cheerful manner. I personally feel I am blessed to have found such a dedicated personal trainer.

Team Lean Vicky Team Lean

KS Fitness's Vicky

'The one who made training part of her every day life.'

Weโ€™ve been working together now for almost a year and Iโ€™ve honestly been so impressed with how Vicky has taken to the training. She puts so much effort into each session we do and even when she canโ€™t quite do something she always gives it a go.

The training we do has constantly been updated and tweaked to give her body maximum benefit, with different variations and changes to keep the body guessing. Vicky is always willing to try new things and push herself, and itโ€™s a pleasure to work with her so often week in week out.

Her results speak volumes and all the hard grafting is paying off. Well done Vicky ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘Œ๐Ÿผ๐Ÿ‘Œ๐Ÿผ๐Ÿ™Œ๐Ÿ™Œ๐Ÿ’ช๐Ÿผ๐Ÿ’ช๐Ÿผ๐Ÿ’ช๐Ÿผ

After struggling to find some consistency in training and nutrition, I decided that enough was enough and it was time to invest in myself. After browsing instagram/stalking his website, I contacted Kev about getting started with some sessions.

Iโ€™ve used a few different PTs before, but I can honestly say that Kev tops them all! Heโ€™s super knowledgeable, experienced, and reliable - as well as a genuinely great guy. Itโ€™s clear that Kev loves what he does and has a real passion for helping people. I feel like whenever I hit a PB, or my measurements have gone down, Kev is just as happy about it as I am! Our sessions are varied and challenging, but genuinely a lot of fun and I look forward to them (burpees aside, obviously!).

Iโ€™m so thrilled with how our sessions have been going and how my body has changed as a result. I feel so much more confident in myself and have fallen in love with training. Kev has helped me to finally find the consistency that I was looking for which Iโ€™m so grateful for (even if Iโ€™m constantly having to buy smaller sized clothesโ€ฆ)

I honestly canโ€™t recommend Kev enough - if youโ€™re sat browsing his website/instagram like I was, 100% get in touch - you really wonโ€™t regret it.

Thank you for getting in touch. We'll get back to you as soon as possible!
