Sean O'Shea

I have 8 years of coaching experience here, helping busy professionals to build muscle and reduce bodyfat, get incredibly strong and improve both physical and mental health on their journey to being in the best shape of their life and becoming more confident in their own body.

Drawing on my array of knowledge and vast experiences of working with hundreds of different people, as-well as my personal experience of going from a skinny guy to packing on muscle myself and winning bodybuilding competitions, I can help you get the best possible results! And as a family man now with a toddler, I understand the need of maintaining a healthy lifestyle, making your exercise routine and nutrition a sustainable part of your life around family and work.

I'm a very supportive coach, both in and outside the gym, but also pushing you past your perceived limitations. I'll guide you with strategies of controlling your nutrition, strengthening your mindset and improving your habits, all whilst still enjoying your lifestyle.

I'll meet you on your level and teach you everything you need to know with lifting weights to work muscles effectively, get stronger and perfect your technique, so you can enhance your performance and movement capabilities without pain. Along with a customised training plan on my app, to give you structure, taking away all the guesswork and gaining confidence in the gym.
