The Core Master is the first fitness product that works the outer, middle and deep inner core muscles…. all at once. Due to the engineered registered design of the Core Master, it works better than anything similar on the market.


With over 100 different exercise variations, Core Master is suitable for all levels, from complete beginner to elite athlete.


The Core Master is a balance board with a centrally located ball which allows the user to roll, tilt and rotate the deck and plank whilst balancing and moving simultaneously through a library of traditional and exclusive exercises. 

Core Master exercises are both isometric and dynamic, not only working all the layers of the core, but every muscle in the body simultaneously.

The Core Master works not just your abs but your WHOLE core from inside out:


Planking works the middle core TVA (Transverse Abdominis) also muscles in the back, glutes, legs and arms.


Balancing, whilst planking on the Core Master, also works the deepest core muscles in and around the spine. This will increase your spinal strength and stability. This plays a major role in preventing and treating spinal injuries, making the Core Master ideal for physiotherapy and sports therapy.


Moving forward and backwards, whilst balancing and planking on the Core Master, flexes and extends the outer six-pack abdominal and back muscles. This is like doing sit ups/crunches and back extension exercises, therefore working those visible muscles too!

The sense of instability and movement the Core Master creates, forces your whole core to stay engaged, going far beyond the benefits of a standard plank or balance board.
