I am from Iceland, the land of ice, snow and a few volcano’s.
I started pretty late in the fitness industry, I did not find my passion until I was 27 years old and started training in a military style fitness center that concentrated on Boot Camp type training. At the time I was working in the film and television industry as an Assistant Director and not really the athletic type. But that was about to change. I trained at Boot Camp for about two years before I began coaching there. I have since been involved in many athletic events and in 2010 I was introduced to Crossfit. I have competed in the European Regionals five times, once as an individual in 2012 and stood three times on the podium in the team competition winning 3rd place in 2011, 2nd place in 2013 and European Champions 2014. I have also competed three times at the Crossfit Games in Los Angeles in 2011, 2013 and 2014.

I am passionate about suppoting people to make positive changes in their lives and achieve their goals. Having previously worked in the charity sector supporting homeless individuals I embarked on a career change 5 years ago, returning to my first passion health and fitness (I called it sport when I was young). I have 4 years personal training experience and have coached a diverse range of clients from experienced atheletes, to novices and individuals who are returning to exercise after a long break. I provide guidance and support in starting their journey.
I first encountered  Crossfit 4 years ago . I love the feeling it gives me of being able to push my body to its limits and the sense of community that CrossFit provides. It has constantly provided me with new challenges and areas for self improvement as both an athlete and a coach.
I recognise that people’s motivation to train differs and hence tailor programs to meet your goals. As a qualified physiotherapist I adopt an evidence-based approach to both exercise, health and nutrition. I believe the key to results is consistency, making gradual and sustainable changes to ones lifestyle. I remain very wary of any magic pills, fads or shortcuts.
I recognise that embarking on anything new is exciting but may bring up feelings of trepidation. I feel privedged you have entrusted me with your fitness and promise to guide you safely through your journey towards your goals and do all I can to make it fun, enjoyable and most of all effective

I started CrossFit two years ago out of sheer competitiveness with my younger sister. I tried one class with her and I was hooked! I love the sense of community that is so integral to Crossfit. I love the fact that Crossfit challenges me and brings balance to my life. I’m addicted to the feeling of physical, mental, and emotional strength that comes from catching a heavy barbell.

I love coaching because I get to help others push themselves and perform feats of strength and endurance of which they had no idea they were capable. I find helping someone increase their squat numbers from week to week or seeing a coaching cue transform someone’s snatch incredibly satisfying.

Before CrossFit, I was a self-professed cardio and yoga bunny. Now I can usually be found in the corner of the box practising Olympic Weightlifting or working through the Starting Strength programme.

I believe that a solid strength foundation is the key to any performance or weight loss goals. Whether it’s improving your deadlift or clean or simply getting your first pull-up, I can help you develop the strength to improve your overall CrossFit performance.

I have been in the fitness industry for 14 years, starting out as a personal trainer. I am also an amateur boxer. I have always enjoyed coaching 1-1 and groups. I’ve trained in various concepts including Pilates, spinning, circuits, UFC Fit and Crossfit Level 1. A few years ago I started working for a gym who’s equipment resembled at  ‘PT playground’ with fitness frames, Olympic lifting platforms, and a whole host of awesome functional kit that you just don’t see in mainstream gyms. There is where my passion started I started training with a coach and working my way through the WOD’s. As a boxer I have always enjoyed a challenge and pushing myself to the limit. This is what I loved about Crossfit alongside the technical aspect of lifting.  I absolutely love seeing people get sucked into it as I did and watching people improve week to week from coach potatoes to an athlete within their own right.

I also have a huge passion for food and nutrition. I am a certified Advanced Sports and Exercise Nutritional Advisor with the Health Sciences Academy. What and when you eat are important considerations when it comes to sports performance. Whether you are a competitive athlete or just enjoy regular workouts, a healthy diet will help you train with greater levels of energy, increase your strength and stamina and recover faster between workouts. It can delay the onset of fatigue during training and help improve personal bests.

I have worked with a wide spectrum of clientele. My aim with everyone is to teach them about food and nutrition and their training in a realistic, practical, interesting way.

I am a strong advocate of science-based advice and am skeptical of anything bearing unsubstantiated claims. I do not sell any nutritional product or supplements. I believe that physical activity should be integral in everyone’s lives no matter how old they are.

As mentioned I am an amateur boxer and as a competitive athlete myself I have also gained knowledge from my own personal experience. I understand the importance of athlete’s diet and how to ensure it provides enough energy and nutrients to fuel hard training and promote rapid recovery whilst maintaining body weight within safe boundaries for health and performance.

When I advise anyone on their nutrition and programming I monitor their weight and body composition and provide education and training to each athlete. I create customised diet and exercise training programs tailored for each individual, no matter what shape they are in. We all have different lifestyles, work schedules, eating routines and health/fitness goals. Everyone needs support and guidance to succeed in reaching their goals no matter who you are.

I’ve been involved in the strength and conditioning field for the past 20 years, both as an athlete and coach.  In my teenage years I started out by doing bodybuilding but soon moved towards powerlifting and Olympic weightlifting and have had the pleasure and fortune to train with and be coached by top international athletes and coaches such as Pantelis Filikidis and Dino Marcuz. I am still an active competitor in the Masters’ category and have held the British title for 3 consecutive years (’10, ’11 & ’12).

As a personal trainer and coach, I specialise in a number of fields including weight loss and weight gain management, strength and conditioning, speed and agility, increasing flexibility and raising energy levels.  I also coach Olympic Weightlifting in schools and CrossFit gyms in central and greater London.  I see far too may people training for years on end without getting the results they want.  Motivating yourself isn’t always easy and the next step takes knowledge and guidance.  Whether you want to improve your Olympic weightlifting and CrossFit WODs or increase your cardiovascular fitness, strength and flexibility in a fun and challenging environment, together we will design a fitness and nutritional plan tailored to your ability, needs and time requirements.  And we will get there.
