A Typical Class

CXWORX® really hones in on the torso and sling muscles that connect your upper body to your lower body. It's ideal for tightening your tummy and butt, while also improving functional strength and assisting in injury prevention. It'll help you run faster … play harder … stand stronger!

Ground-breaking scientific research means Les Mills CXWORX® features the most efficient exercises for maximum effectiveness ... 30 minutes is all you need!

Like all LES MILLS® programmes, a new CXWORX® class is released every three months with fresh music and choreography. 


Your instructor explains which muscle groups make up the core and why training them is so important, then takes you through a warm-up designed to gradually activate those muscles before the real work begins.


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.


Before you know it, your 30minutes is up and the class is ending. Your body knows it has been tested, but as you regroup, you're mentally scheduling your next class.


Getting Started

How often should you take a class?

Because your core is challenged in CXWORX®, it's best to take a rest day between classes to give your body time to recover. You can also tack CXWORX® on the end of other Les Mills programmes, or before doing a cardio class.
