World's First & Only!

The Kewlus cobra bag is the world's first & only modular freestanding reflex punching bag. No other cobra bag bag has such a high level of component quality and reliability. No other cobra bag offers you the ability to switch components in order to match your training goals. Now you can instantly switch from working on speed and reflexes using the Striker Spring and the Speed Target to working body movement using the Reacher Spring and the Prime Target to developing raw power in your punches using the Prime Spring and the Power Target. Unlike other cobra bags, the Kewlus system offers not just one, but unlimited training options.

Caring for the Environment through Sustainable Design

One major factor of the modular system is sustainability. Every part is designed to be replaceable. If something breaks or wears out, you simply swap out that one component instead of tossing the entire unit. This approach cares for the environment by drastically reducing waste while extending the life of your gear. By investing in a KEWLUS, you're helping to care for our planet.

Loved by Champions

Appreciated by boxing champions like Tim Tszyu, the McKenna brothers, the Moloney brothers, and embraced by boxing coaches worldwide, the Kewlus is revolutionising reflex training and is fast becoming the go-to training tool for the top athletes.

Pounders - Boxing & MMA Training Gloves that don't Stink

You’ve seen my DIYs for these — now be one of the first to witness the revolution. Pounders are the world’s first modular training gloves for boxing and MMA that don’t stink. No laces, no Velcro, no sweat-soaked padding — just pure, rinse-clean performance that lets you train harder and more often. A limited early release will be sent out free to selected boxing and MMA professionals — and a few loyal KEWLUS fans.

The Striker (KS3s)

The Striker (KS3s) is a more resistant and therefore faster spring that is able to handle heavier loads without compromising on speed. Intended to be used as an alternative to the Prime (KS3), it sets the stage for training with heavier targets while maintaining incredible rebound speed.

Now Available

The Reacher (KS3r)

The Reacher (KS3r) is designed to increase the reach and range of movement without compromising on speed. It's ideal for working on defence, such as evasive movements, footwork and learning to gauge distance to target.

Now Available

Power Target

The Power Target Ball is crafted from genuine leather, just like the Prime Target Ball, but it’s 25% heavier and slightly larger. Designed to boost your punching power, it’s the perfect companion to the Striker Spring for developing strength and impact.

Kewlus on TV!

Shark Tank Australia was a fantastic stage to showcase Kewlus, but our priorities diverged: the Sharks chased fast returns, while I’m committed to lasting innovation and community impact. In the end, they passed on my ethos, and I wouldn’t have it any other way.

What's a Cobra Bag?

Cobra bag is a name synonymous with the reflex punching bag. This is a type of free-standing punching bag that incorporates a punching target (often in a shape of a ball) on top of a rod or pole that is able to flex back and forth. The cobra bag is one of the best training tools for boxing training and is often compared to the floor-to-ceiling bag. It's ideal for developing a high level of hand-eye coordination and defensive boxing skills. The interactive nature of the cobra bag makes it fun to train with.
