We have created various options, that will cater for all ages, bodies and fitness desires.

High Intensity Training

High Intensity Interval training (HIIT) is a training technique using quick, intense bursts of exercise, followed by short, sometimes active, recovery periods. The magic of HIIT classes, is that it keeps your body burning fat even after you leave the gym. It is extremely effective for transforming your physique. Whether you are a novice or an expert, the classes are designed to push you to the next level.



Stretching is usually used to warm up and wind down before and after a work out. You can also use stretching exercises to increase muscle control, flexibility, and range of motion. Your Trainer will guide you through a progression of stretches to improve all-round flexibility and mobility. You will see whole-body benefits, we place specific focus on the problem areas and muscle groups affected by the HIIT classes.


Punch & Defence

Punch: Our expert professional boxer and MMA trainer, has created a cardio punch session incorporating boxing movements.  He ensures his sessions are always hard but still fun, promising to get the best out of you.

Defence: Our Defence class incorporates a mixture of Kickboxing and Martial Arts to provide an enjoyable cardiovascular workout. The class is taught by our professional Mixed Martial Artist  with a current record of 4-2, IBJJF British National Jiu Jitsu Championship Gold Medalist, 2 time WCMMA Light-Heavyweight Champion and a Kickboxing Instructor to name but a few qualifications!

My induction session was fantastic, there was so much attention on me; most importantly I was listened to. I could see they wanted to ensure I got the best out of my time with them. I met with a physiotherapist who talked with the trainers to ensure I was having workouts tailored to my goals. I love the facilities so many special touches, like the basket of toiletries; such a personal touch.
