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 qualites 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.

The swaying movement that you get with normal hanging bags is also less 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 heavy-duty UV resistant marine vinyl they are very durable and come with a 2-year warranty.


What size of Aqua Punching Bag should I choose?


Types of Aqua Training Bags
Currently there are six types of Aqua Punching Bags available in various sizes, weights and colour options.Due to the production methods for the multi-colour option bags each bag has its own unique swirling pattern.

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 practicing accuracy and timing to perfect head shots much like normal slip bags, though heavier due to being water filled.

Medium, Heavy, & Super-Heavy Bags
There’s the mid ranged 15 inch Energy model weighing 75 pounds followed by the heavy 18 inch and super-heavy 21 inch Punching bags weighing 120 and 190 pounds respectively. The final model is the body shaped 150 pound Bruiser Bag. 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 it is best to avoid the larger 18″, 21″ and Bruiser versions as their heavy weight means it is no easy task.

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:

How to Hang, Fill, & Drain your Aqua Bag


Hanging the bag

  • Location:

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:
  • Option 1 – Loop the chain around the beam and attach with a quick link.
  • Option 2 – Eye Bolt – Drill a 1/2 inch (13mm) hole through the beam and insert an eye bolt through the hole. tighten the eye bolt by first placing a washer over the top and tighten the bolt with a spanner or socket.
  • Option 3 – Eye Lag Screw – Drill a hole 1/8 inch (3mm) smaller than the diameter of the screw’s thread through the beam and screw the eye lag into the drilled hole. Place a bar or screwdriver through the eye to fully tighten the screw into 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.
Tip: Always ensure the bag is at room temperature before filling. A cold bag will resist expansion making it more difficult to fill with water.
  • Remove the filler plug using a No.2 Phillips screwdriver. NB. When removing the filler screw you may see that the rubber filler plug seal has remained in the opening. If so use a pair of long nosed pliers or tweezers to pull the plug from the hole and push it back into the screw so that it is ready for refitting.
  • Attach the supplied sweeper nozzle to a garden hose NB. See item below “How do I connect the Aqua Punch Bag filler nozzle to a hose?”
  • You may wish to place a container beneath the bag to catch any water that will drip off the bottom should you overfill it.
  • Insert the filler nozzle into the bag and slowly turn on the water. Note: If you don’t have a water flow control fitted on the filling end of the hose then this process will be a two person task, one to hold the filler in place whilst the other turns on the mains tap.
  • Do not press the nozzle too far into the opening as air needs to be allowed to escape through the same passageway as the bag fills.
  • Turn off the water supply once the level of the water reaches the fill hole. Note: A bag does not have to be completely filled. A full bag will have a firmer feel when struck. If you prefer the bag to have less firmness then try a three-quarter fill .
  • Replace the filler plug and tighten gently. Do not overtighten or you will risk damaging the plastic screw head.

Tip: Tip: On the Bruiser Bag model once filled you can fully inflate the head area by using a hand pump that has a needle nozzle, as used for footballs, which can be inserted into the hole in the filler screw. This can also be done on other models to keep the top of the bag wrinkle free but it is not essential.

how to fill the Aqua Punch Bags

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 or Methanol based antifreeze for outdoor winter use as it is poisonous (more information on antifreeze can be found at

Can I leave my Aqua Punch Bag hanging outdoors during winter?

  • Filling capacities
  • Antifreeze ratios

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. 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 10 C then get in touch and we’ll workout the ratio you’ll require.
