Personal Training
Our certified personal trainers create bespoke fitness programs tailored to individual body goals and fitness levels. Each session combines strength training, boxing workouts, and nutritional guidance through a proprietary app. With small group sizes limited to five women, trainers provide focused attention while tracking progress meticulously to ensure continuous improvement.
Boxing Classes
Women-only boxing classes feature individual equipment stations for bag work, weighted conditioning, and abs training. Structured heart rate zone programming maximizes calorie burn while improving cardiovascular health. The non-intimidating environment with personal equipment ensures comfort for all fitness levels during these high-energy, fat-burning sessions.

Our habit-based nutritional coaching replaces restrictive diets with sustainable lifestyle changes. Trainers guide clients through personalized food plans using a habit tracker app, focusing on behavioural changes rather than calorie counting. This approach develops long-term healthy eating routines that complement individual fitness goals and lifestyle requirements.

Liverpool Personal Trainer Dave Mercer at Gym Reb3l
Dave is the best trainer I have ever had. He motivates me no matter my mood and so have seen amazing results from his training sessions and nutritional advice. He's always happy to help, even outside of the sessions keeping me motivated through the week. I would never go to another trainer. The classes are great too! A great way to mix with people but the class sizes aren't too big!

Great place if you are looking for a relationship based, dedicated PT service via Dave Mercer! Not only you get dedicated time and sessions, bonus is all the insight, information and understanding of your own body! You get to try and understand what works for you and focus on strengths with "off the grid" help from Dave! The result, not surprisingly, is an excellent state of mind and body! The whole place is friendly with good vibes! Give it a try.....

I have been working with dave mercer for just over a month. The improvement in my fitness and mindset has been fantastic. I love the personal training sessions and the gym has all the equipment you need. Also the one to one coaching and support from Dave has been amazing. Post baby I lost all confidence and was struggling to fit in exercise into my work and home life. I travel for work and this is an added complexity. Dave has given me home workouts which I can do easily wherever I am. The app which does this is brilliant. The nutritional support has been invaluable to me. I had found that I
