What is it?

Improving the functional fitness

The Less Mills CX Worx class is an intense thirty-minute minute core-training workout designed to tighten and tone your midsection in the shortest amount of time possible. The class utilises your body weight, free weights and resistance tubing to challenge your balance, co-ordination and to improve your functional strength. The class is based on cutting-edge scientific research. CX Worx is all about building core strength, improving the functional fitness of the abdominals, mid-section and glutes – as well as working the cross-slings, which run from the upper to lower body. Basically, CX Worx targets everything from the mid-thigh up to the shoulders (which is an area also known as your trunk). In this class you burn up to 200 calories and more – the same calorie burn that our Aqua Fitness class offers.

Who is it for?

Play harder, stand stronger.

The class program is designed for all fitness levels as every exercise has different levels to suit any participant to get the most benefits from this class. Our mid-section is our powerhouse – so you need to have a strong core and glutes to be able to perform day to day activities as well as training. A quick and efficient class, CX Worx is ideal if you only have thirty minutes to spare to make it into the gym. The class mixes choreographed routines with energetic and chart-topping music that will bring you back for more. It will help you run faster, play harder and stand stronger.

2- Your workout consists of exercises that both isolate (like crunches and leg extensions) and integrate (like standing balance and hovers) the various muscle groups. It challenges you and you really feel the benefits.
