I’ve been going to Double Jab for just over a year now and it’s honestly one of the best decisions I’ve ever made. From the very first session the gym has felt welcoming, inclusive and supportive. The coaches are not only skilled but genuinely lovely people who create a positive community where everyone feels encouraged. Before joining I could never stick to exercise. At Double Jab I am always learning, always challenged and always motivated to come back. The impact on my physical and mental health has been huge. I feel stronger, healthier and more confident than ever! The membership is also really affordable compared to most places, especially considering the quality of training and support you get. Double Jab isn’t just a boxing gym, it’s a community that truly lifts you up. Highly recommend to anyone thinking about giving it a go! More...

This boxing club is amazing. The coaches are knowledgeable and motivating, and they really push you to get the best out of every session. The workouts are very hard but rewarding, and the environment is supportive. I encourage everyone to try at least one session. More...

Started training here a few weeks ago and I’ve been blown away by the level of professionalism and support offered by the coaches, staff and club members. No overblown ego’s - just really enthusiastic people who will push you to be the best you can be. Highly recommended for beginners. More...

childrens classes are over crowded and i obseved over my time being there that only what looked like favourite children being focused on. I even witnessed a parent pointing this out vocally at the edge of the ring. I travel an hour to get there and longer to get my child home. Not any more. More...

Q&As

By listening to each client as an individual, and working around your life style in terms of energy levels, capacity and time you are able to dedicate.

Training efficiently and consistently rather than far and few between intensely.

I love boxing, I love working with different people, helping people with different life styles find the most efficient way to reach their goals, I see my clients goals as my own personal goals that need reaching too.

Being in control of my schedule and being able to be a professional boxer around that.

I have over 10 years experience as an athlete and continue to compete today as a professional boxer.

I have also been lucky enough to work with all kinds of athletes ranging from beginners all the way to olympic and professional athletes in different sports.

I have worked with many different body types and abilities, as well as faced many different challenges and obstacles with my own training and clients (injuries and illness) making me confident whatever your goal is, I can help you.

I provide an online service, where I will write you a customised program over 4 - 8 weeks, you will be able to see this on your phone though an app called TrueCoach. I will be able to see your progress as you go, send you messages, and we will keep in contact every other day to see how you are feeling, and if we need to make adjustments based on your energy levels and life around training.

I have been vaccinated, I am a young healthy guy and have had covid twice. I understand people have different symptoms - please let me know if you are worried about catching covid and I will do all I can to make you feel comfortable.

Services

One to one boxing coaching is the fastest way to improve your boxing skills.

Whether you’re a complete beginner or seasoned fighter, I can help you improve your skill with personalised pad work, drills, and eventually technique sparring (sparring at 50 - 70% with drills and techniques in mind) .

I will also show you unique warm ups and mobility routines used by boxers to gain range of motion and fluidity when fighting, as well specific strength and conditioning routines for boxers that will optimise power and volume in punching.

Personalised training programs to reach the goals you set.

I will send you your personalised program through the app TrueCoach, and we will keep in contact every training day to monitor progress and make changes if need be.

Whatever your goal may be, whether it is to rehabilitate from coming back from an injury, increase your bench press, shave off time running for a marathon, or fit into a dress you used to wear. I am confident I can get you there with personalised strength & conditioning sessions built around your individual needs and goals.
