Due to the qualities of water their weight to size ratio is also greatly increased compared to ordinary punch bags and their better ability to absorb shock means a more intense workout and less swing movement. When you hit one of these bags for the first time, you will never go back to working out with a traditional heavy bag. You can also add the Aqua Training Bag Sensor to one of their heavy bags and get comprehensive feedback of your individual workouts via the phone app and track your progress over time.

Available in a range of sizes and unique colours, they’re ideal to replace your speed bag or heavy bag in both your gym or garage workouts.

Aqua Punch Bags are created by one of the oldest and well-respected manufacturing companies in the USA, they are incredibly durable and can withstand even the most impressive combos.

Aqua Punch Bags vs Traditional Punch Bags

Aqua Punching Bags or Aqua Training Bags as they are also known have become popular in boxing clubs and fitness gyms in recent years after gaining praise from many top pro-boxers and martial artists around the world. These water filled punch bags have a unique feel to them compared to traditional punch bags with many comparing it to more like hitting a real body, which makes sense when you consider the human body is made up of around 60% water.

Due to the qualities of water they absorb the impact of blows far greater than ordinary punch bags meaning less stress on the joints which allows for longer more intense workouts, which in turn reduces the risk of aching wrists, shoulder, and elbow joints often associated with heavy bag workouts. The shape of the bags also allows for upper-cuts to be practised efficiently doing away for the need to have a separate dedicated upper-cut bag.

As water absorbs shock far greater than the filling you find in traditional heavy bags the swing movement is also less noticeable on the heavier versions of the Aqua Punching Bags, which, due to the density of water, are very heavy indeed! Another added bonus is as they are delivered empty and you self-fill you avoid the "heavy item" shipping costs associated with normal heavy bags.

Being constructed from a heavy-duty UV resistant vinyl compound they are very durable and come with a manufacturer's warranty.

What size of Aqua Punching Bag should I choose?

Types of Aqua Training Bags

Currently there are five sizes of the teardrop shaped Aqua Punching Bags each available in various colour options. Due to the production methods for the multi-colour option bags each bag has its own unique swirling pattern. There is also the Aqua Bruiser bag which is a body shaped bag and is sized approximately to the head and torso of a 6' 1'' tall male. 

Aqua Head Hunter Bags

The two smaller sized 9 and 12 inch bags, (the inch measurements refer to diameter size), are called Head Hunters which are exactly what the name implies, bags for practising accuracy and timing to perfect head shots much like normal slip bags, though heavier due to being water filled. Aqua Head Hunters will swing gracefully or erratically based on the way you hit it or your trainer moves it on you, allowing you to also practise your defensive skills by honing your head slipping and bobbing. When filled the 9" model weighs 15lbs with the 12" being more than twice the weight at 35lbs.

Medium, Heavy, & Super-Heavy Aqua Bags

There's the mid ranged 15 inch model weighing 75 pounds followed by the heavy 18 inch and super-heavy 21 inch punching bags weighing 120 and 190 pounds respectively, as well as the body shaped Bruiser Bag at 150 pounds.  Keep in mind that if due to space restrictions you need to hang and remove your bag each time you want to use it then you might want to avoid the larger 18, 21 inch and Bruiser Bag versions as their heavy weight means it is no easy task. If this is the case then the 15 inch Aqua Punching Bag is ideal for this purpose as its 75lb weight makes it easier to manage.

The following table shows the various types along with their unfilled and filled weights in pounds and kilos, as well as a brief description of what each bag is suitable for. With the following links to the individual bag types:

What's included with the Aqua Punching Bags?

Each Aqua Punch Bag comes with instructions for installing, a steel hanging shackle to attach the bag to a chain, a nozzle used for filling the bag, (see the article below on what hose connectors are required), and a spare filler hole cross-head screw plug. NB.We also add a free connector to allow you to connect the filler nozzle to a hose.

How to Hang, Fill and Drain your Aqua Punching Bag

Hanging the bag


NB. For ease of use with the heavier Aqua Bag types it is best to hang your bag first and then fill it.

Hang your bag from a sturdy overhead beam or on a free-standing heavy bag rack for which the floor must also be strong enough to hold the weight. Make sure the overhead beam can hold at least four times the weight of the bag you have. Pick a location that is free from surrounding obstacles. You want a minimum clear area of 5 feet around the bag to work your boxing combinations. If you are also using kicks then this area may have to be greater depending on the kicking techniques you are using.

NB. Aqua produce their own Aqua Bag Hanging Kit which has been specifically designed to take the weight of the heavier Aqua bags.

Overhead Beam Hanging:

There are three ways you can attach the bag to the beam:

NB. The loop-over or eye bolt options should be used when hanging the heavier bag types, the eye lag screw should only be used for the lighter Head Hunter models

Hanging Height

When using the Aqua Punch Bag Hanging Kit attach the quick connector at the swivel eye end of the chain to the shackle on the bag and use the quick connector at the other end of the chain to attach it to the eye bolt. If you find the height of the bag is too low you can raise it by choosing a different chain link to attach to the upper quick connecting link . On high ceiling fittings an additional chain may be required. The height of the bag can be varied depending on your training style, though usually the top of the bag would be set at your head level.

Safety Tip: Always wear hand protection when using the Aqua Punch Bags. Repeatedly striking the bag bare fisted may result in sore knuckles or abrasions. Wearing padded gloves which also support the wrist are recommended and also allow the user to train with greater intensity.

Filling the bag

Tip: As mentioned earlier you should fill the heavier types of Aqua Bags once hung; otherwise it can be a two or even three man job to lift them into the hanging position.

NB: Always ensure the bag has been stored at room temperature for a few hours before filling.

A cold bag will seriously resist expansion making it more difficult to fill with water.

Tip: If working in cold conditions placing the bag in a bath of warm water for 15 minutes will make it more pliable allowing it to expand easier when filling. Avoid overly hot water which could cause damage to the seam.

It is also helpful (but not required) to inflate the bag with air to expand the cavity before filling with water. That is just an extra step to keeping those pesky wrinkles at bay. Having a buddy to help makes the process much easier, however, it can be done!

Next follow this step-by-step to fill the bag:

Draining the Aqua Punch Bag

Draining the smaller Aqua Bags is just a case of removing the filler screw and turning them on their side to allow the water to drain out. Doing the same with the heavier bags is not as simple, especially if working alone. If you don't have help at hand to help unhook and lower one of the big bags then a solution to make it easier is to siphon the water out whilst the bag is hanging. You'll need some 5mm hose to insert into the filler hole and a container placed on the floor. If you've never tried siphoning anything before here's how to do it. Feed the hose into the bag until it reaches near the bottom, keeping the other end of the hose lower than the base of the bag, you then suck on it to start the water flowing. Once the water comes through it will keep running as long as the exit end of the hose is kept lower than the end in the bag. Depending on the size of your container you're using to collect the water in you may need to repeat this several times until sufficient water has been removed to make the bag light enough for one person to handle.

CAUTION - you should not use the siphoning method if you have added an Ethylene based antifreeze for cold weather use as it is poisonous (more information on antifreeze types can be found at

How do I connect the Aqua Punching Bag filler nozzle to a hosepipe?

We include a free hose connector with each Aqua Bag order which allows you to attach the filler nozzle that comes with the Aqua Training Bags. We provide two types of connector, a Male Hose-Tail that fits directly to the hose, or if you have a Hozelock (or Hozelock compliant) connector already on your hose then our Hozelock Adaptor will do the job.

Can I leave my Aqua Punching Bag outdoors in winter? 

Yes you can leave your Aqua Bag outside during cold spells, or in an unheated outbuilding, but if you want to ensure that the water in the bag doesn't freeze (it won't be much fun hitting a block of ice!) then you need to add some antifreeze.

Antifreeze in general gets an excellent rating(1) as being safe for use with PVC, however it should be noted that ethylene glycol based antifreeze is probably your best bet as ethylene glycol in its neat form also has no adverse effects on PVC material. Propylene glycol based antifreeze is far less toxic, but it should be noted that propylene glycol in its neat form has been shown to have a moderate effect on PVC when used for long time periods and may cause some weakening of PVC materials.

The table below shows the approximate filling capacities of the different Aqua Bag types and the different ratios of antifreeze required for each bag depending on how much cold protection you require. The table shows the amount of antifreeze required to prevent freezing for -5, -8, & -10 centigrade temperatures, if you really want to train in temperatures below minus 10C then get in touch and we'll workout the ratio you'll require.

NB.The nature of the vinyl skin means it will be less pliant in colder temperatures and therefore even with antifreeze added the bag will have a harder feel to it compared to when it is hung in a warmer environment.
