Sean O'Shea

I have 7 years of coaching experience here, helping busy professionals to drop unwanted body fat whilst building muscle, getting strong and improving 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. 

As a husband, a dad and a busy professional, I understand the need to maintain a healthy lifestyle, making your exercise routine and nutrition a sustainable part of your life around the time constraints with family and work life.

Drawing on my vast experiences of working with hundreds of different people, as well as packing on muscle myself, doing bodybuilding competitions and completing many educational courses over the last 10 years, I can help you get the best possible results!

Teaching you everything you need to know about lifting weights to train muscles effectively and get stronger, along with a training plan on my app, fully customized to your lifestyle and movement capabilities, taking away all the guesswork.

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