I Tried The Crazy-Looking Device Kate Hudson Uses to Tone Her Entire Body

Meet the HydroCore bag. - by Kristin O’Brien

I have been a movement coach specialising in unconventional training modalities for quite a while, and I thought I had seen it all until I came across the HydroCore bag around 8-months ago.

Kate Hudson, who took to Instagram to share a new workout she’s been doing, filmed herself spinning with what seemed to be a water-filled device, around her head in circles, with direction from her trainer Brain Nguyen. “This gives ‘staying centered’ a whole new meaning for me,” she writes in her caption. “First time taking this for a ride, definitely not the last.”

I am a big fan of any weight that throws your body off balance and forces your core to kick in, and will often use sand bags or a mace in order to achieve this, but the HydroCore bag is unlike any other training tool I have ever used – so I had to try it.
Here’s how it went.

Changeable weight 

The unique, water fillable design allows one to easily adjust the weight to fit their ability.  It was quickly apparent that I did not require a lot of weight to get a phenomenal workout as the movement of the water adds an element of difficulty that requires full body engagement. 

Encourages correct movement 

The moving water within the bag gives immediate feedback that lets you know if you are moving correctly or not.  Whether your goal is to keep the water still, allow it to flow or force it to crash, the water does not lie.  

The clear belly of the bag also allows you to use the water as a visual aid that teaches us how to move.  It will expose errors and imbalances in your movement patterns! 

The HydroCore’s soft make up and easily adjustable load make it the perfect tool to learn complex swing patterns and introduce rotational strength.   One must learn to work with the movement of the water to create a smooth execution.  There is also a great deal of carry over into other modalities such as bulgarian bags, mace,  clubs, kettlebells, ropes and even barbells making it a very versatile weight.

It’s easy to transport

Having every weight from a kettlebell, to a mace and a sand bag with you can take up a lot of space, whereas the HydroCore can be filled and then emptied making it easier to store it and easier to travel with. Therefore it is a good option for people who like to bring their equipment and train outdoors or travel with it. 

I originally purchased the Hydrocore as a lighter alternative to a bulgarian bag. I quickly learned that it is it’s own beast with it’s own unique set of values. 

Hydrocore is also now available in Australia. You can purchase one by reaching out to them via the HydroCore Australia instagram page.

8 Of The Best Exercise Shorts That Will Power You Through A Summer Of Movement

It’s official: Shorts Season is officially here. While lockdown has seen many of us realise that activewear is less something to be worn for a workout and more a uniform we choose to do any and all daily activities in, when the warmer temperatures roll around, that favourite pair of sweatpants and leggings sometimes don’t cut it. Sure, they might be a staple in any wardrobe, but the Aussie sun doesn’t listen to reason, no matter how comfortable or cute it might be. And when it comes to summer, working out in leggings can feel like being trapped in a sauna, the sweat pooling at your ankles and around the waistband – as well as those other areas we won’t mention here. 

But as we transition from leggings to shorts, it becomes clear pretty quickly that not all shorts are created equal, and certainly not all shorts are fit for a workout. Take it from us at Women’s Health HQ, we’ve been there, tried it and lived to see the consequences. From the shorts that look cute but ride up to show your undies on the run, to those that feel like being strapped into a harness that’s digging into your hip bones. Then there are the fabrics that can cause chafing – a big no – and those that basically shine a spotlight on any area you might be sweating. 

Thankfully, a number of brands are here to cater to your exercise needs with innovative materials, fabrics and sustainable options to see you through a summer of movement. Regardless of your workout preferences or daily activity, we’ve selected the best shorts that will ensure you feel good in your body, shorts that get you excited to embrace the day and attack it with energy, that make you want to get outside and enjoy the outdoors, whether it be walking, running, or socialising in the park. Here are our pick of the best bike shorts below. 


Uptown Biker, $240

What says summer more than a pop of orange and the sleek shape of these Nagnata biker shorts? With its mid-length and horizontal raised rib side detail, these are shorts you can wear both for a workout and out to meet the girls. Made in Australia with a technical knit fabrication, the double-layer jacquard provides gentle sculpting qualities for the body, making it an excellent choice for light to moderate fitness activities like yoga, pilates or barre.

New Balance

Q Speed Fuel Short, $70

We love the colour of these shorts from New Balance which are cut with a sleek, speedy look that also helps to elongate the legs. Featuring NB DRY moisture wicking fabric, these are the shorts you want for high intensity exercise or long runs, keeping you comfortable and dry. There’s also an interior brief for added comfort and a stash pocket to keep your essentials. 

All Access

Ultra High Rise Zip Front Biker Short, $78

Yes, the colour is amazing but the fit is equally sensational on these All Access shorts. For those who love a high-rise fit and wide waistband that holds you in at the waist, look no further. The sleek, shiny look offers mid-compression and the fabric is moisture-wicking, so you can stay comfortable even during your sweatiest workouts. 


Nike x Naomi Osaka Utility Short, $90

Few things are worse than heading out the door for a run and realising your shorts offer no pockets for those essentials you need. You’re left to hold your iPhone, keys, and anything else you might need in your sweaty palm. Thankfully, Naomi Osaka knows what we need when it comes to exercise shorts and these utility shorts from her collaboration with Nike offer all that and more with a relaxed fit and elastic waistband. 


Session short Tights, $72

When it comes to bike shorts, you want to feel supported and held in but you also want to be able to breathe. These Tracksmith session short tights are exceptional in offering support while still ensuring comfort remains a priority. Forget about chafing, these shorts won’t ride up and down and the fabric offers more coverage and support against the body. 

Outdoor Voices

Relay 3” Short, $48

Who said summer shorts have to be boring? Outdoor Voices brings fashion-forward style and playfulness to their collections with fun prints and exciting colours. We love the relay 3” shorts for their ultralight, quick-drying fabric that also happens to be made from recycled polyester. But more importantly, we love the print and Poppy Swirl is as good as it gets. There’s even a hidden pocket for your valuables, too. 


Align High-Rise Short 6”, $69

If you’re familiar with the buttery-soft feel of Lululemon’s tights, you’ll want to get your hands on a pair of their shorts, too. Made with the same Nulu fabric that their tights are known for, these shorts feel weightless and super soft. They might be our go-to staple for any workout, but the feel is so second-skin that it’s hard to not wear them for every other activity, too. 

Spiritual Gangster

Seamless Biker Short, $112

These biker shorts from Spiritual Gangster move with you, thanks to a three-tiered compressive waistband that offers a flattering high waist that hugs you in all the right places, without proving constrictive. They offer medium compression but are built for all day comfort, and the colour is a true summer staple because, let’s face it, who doesn’t love tie-dye?
