I am a Personal Trainer from Winchester that offers 1-2-1 personal training, pair training, online coaching, sports massage, and boot camps. I run a personal training studio in central Winchester that specialises in GP Exercise referral. I studied at Bournemouth University achieving a 2:1 in BSc (Hons) Sport Psychology and Coaching Sciences. Whilst studying at University I also completed a Level 2 Gym Instructor and Level 3 Personal Trainer Qualification. Studying at Bournemouth University has helped me develop my knowledge of the human body and the science behind weight loss, muscle growth, correct nutrition, and sustainable results.

I have always wanted to help people achieve their fitness goals, whether it be via 1-2-1 or through the range of his online coaching plans. I am a committed individual that seeks to help others transform themselves both physically and mentally.

I’m currently completing my final year of a degree in sports psychology and coaching, along side personal training. This has helped me gain a deeper understanding into the world of sport, and also how our minds work when faced with exercise. 


As well as ensuring we set challenging but achievable, goals together during our sessions, one of my main tasks is to make sure you leave with a smile on your face! 

Fitness should be fun, not a task and that is something I strive by. 


I myself have fallen in love with, and understood, what the process of working out and exercise can do for you, both physically and mentally. I aim to spread a true passion for health and fitness, and this will be apparent in my coaching. 



Lift heavy, leave happy.

I can then transfer my knowledge to help people achieve their goals, feel more confident, improve overall mood, and lower stress levels. I have many specialities in different areas of the industry such as Pre and Postnatal training, Nutrition Coach, Lower back pain, GP referral, and level 4 Strength and Conditioning. By qualifying in these areas it has given me the experience to work with a variety of different individuals and their goals. By being a Nutrition coach I am able to combine nutrition and exercise together to achieve optimum results, whether that's a decrease in body fat,  weight loss, strength training or any other goal that you are looking to achieve. We will work together to achieve your personal goals and make sure that it is sustainable.
