DIY Make Your Own Aqua Punch Bag Hack with Polyform Water Buoy

James DIY’s his own Aqua Punch Bag out of secondhand marine parts for £10.
The buoy used in this clip is a Polyform A4 20” rubber buoy. The hoseline adapter came from an airbed.
According the Aqua Bag manufacturers, the more water you add, the harder the bag is, less water = softer bag.
If the bag reaches your desired hardness, but is still saggy or wrinkled, you can inflate with air to tension the rubber bag.

About to do this with a Taylor Made A4...paid full price for the buoy but still $100 cheaper than buying an Aqua bag...Thanks for the vid!

[@martial_life]

No problem! Thanks for watching!

[@jakemcleavy4992]

bought one of these cause they was a cheaper alternative to the overpriced aquabags, which are just bouys with a price tag, amazing piece of equipment.

[@martial_life]

Exactly the reason I did this. It was 16x more expensive to buy an aquabag!

[@retroking949]

where have you been ? Love this video , you should make videos of you just punching and kicking bags . Your style is unique and as an itf tkd fighter myself this is inspiring.

[@martial_life]

Thanks! I’ve been so busy with life lately I haven’t had time to film anything worthwhile, although I still try and get on to keep an eye on comments! I have an ITF background myself, but also both Shotokan and Wadoryu karate and kickboxing! I have plans for more videos and budget DIY training aids, so hopefully will be able to post soon!

@@martial_life Thanks for responding to my comment ! I love your videos and fighting style . What belt are you in itf tkd?

[@martial_life]

No problem, you took the time to comment, it’s the least I can do. I made it to 1st Dan in ITF, but I struggled in classes as I’d done karate for 11 years in Japanese at that point before switching to learning ITF in Korean! 😂

@@martial_life haha i’m going for the 8th kup at the end of the month. I am building a gym at the moment and was looking for an aqua bag and then found this video and am so glad i did !

[@michaelokeeffe7132]

Nice job, i have purchased an A4 buoy, just waiting on my wall bracket to be made. Quick question, what nozzle did you use on the hose to fill it up? Thanks.

[@martial_life]

I used an adapter from an air bed air pump, it wasn’t ideal as it had 2 small holes in, but it did work. A small funnel would do just as well

[@mikecoots7003]

Nice one great idea. Just got an A2 size. what size shackle have used?

[@martial_life]

I’ll have to measure it. The shackle on it was already on when I picked it up (the joys of second hand goods) and the chain was from my old dead heavy bag. I’ll check it out and let you know though!

[@martial_life]

I remembered to check! It’s got a 50mm D shackle on it, about 10mm thick

[@user-xr5sj2jt2p]

How do you fill it up with water? Any other ways to fill it up with out breaking it?

[@martial_life]

I used a nozzle designed for an airbed that fitted the hole. You can buy some specifically for hoses but I was trying to do it on a tight budget. You don’t really need to break it, only the little rubber one way valve inside the fill hole to get the nozzle in properly

[@charlesterwilliams1736]

I need help. I have the exact same buoy but for the life of me I cannot find a anchor shackle to fit over it, None of the Home Depot and Lowes ones are wide enough to fit over the opening. Where did you get your anchor shackle from. I really need your help

[@martial_life]

I got my buoy 2nd hand and it came with the shackle and chain already attached. If you haven’t filled it yet, it might be worth taking it with you to Lowes or Home Depot to see if the store assistants can find something that fits?

[@cb3557]

What is the clip called that is around the loop on the bag? And where could I get one? It looks different from the average carabiner clips I see

[@martial_life]

It’s a D ring / shackle on the bag itself. My bag came with it already attached, but you can get them on ebay/amazon/ hardware stores

[@LeftHookLegend]

Dude put on gloves

[@martial_life]

I didn’t have mine with me when I filmed this. I’ve used them with it since and it’s alot more comfortable!

[@hobocheez]

Hey man, great video! When you’re throwing elbows and knees, does the rubber grab your skin any more than a regular heavy bag? I’d like to buy one, but I’ve never seen one in person and I’m trying to not get raw elbows and knees! Haha

[@martial_life]

Great question. This one doesn’t grab, but it’s more a type of flexible plastic than rubber. It should be fine for elbow / knee sessions

[@hobocheez]

@@martial_life Awesome! Thanks for the reply, man! I really appreciate it!

[@sren1446]

Great. How much water is in the Ball ??

[@martial_life]

It’s about 3/4 full. I just kept going until most of the creases were out. The more water you put in, the harder it is. If it’s too hard, you can remove some water and use an air pump to inflate it to remove the folds.

[@rexetswah4740]

@@martial_life you are correct. I've got mine just over half full and seems just right for me, not thinking of filling to the top anytime soon though 😂🤣

[@martial_life]

Sounds sensible! I only found out about using air to remove the creases after I’d filled mine.

[@rexetswah4740]

@@martial_life it's all a learning process I guess lol

[@vugarmammadov]

Where can I buy this?

[@martial_life]

I picked mine up second hand on facebook, but amazon sell them as Polyform Water Buoys quite cheap

[@vugarmammadov]

@@martial_life Thanks for information

[@user-xc7gb8gj6r]

How did you fill it with water, What hose attachment do you use ?

[@martial_life]

The adapter I used was actually an airbed pump adapter, it worked, but it wasn’t perfect. You can get some of those quick release style garden hose adapters that fit well though

[@yetigriff]

What attachments did you use on the hose?

[@martial_life]

It was the air nozzle from an air bed pump. It wasn’t ideal, but it did the job on a budget!

[@yetigriff]

Thanks mate How did you attach it to the hose,

[@martial_life]

It sounds crude, but I just wedged the hose into it, no proper fitting, which is part of the reason I spilt so much water filling it

[@deep-boxing2530]

Where did u get it by 10eur?

[@martial_life]

2nd hand on Facebook market place

[@martial_life]

Hi everyone, thanks for watching! For my next diy budget project, I’m considering either a break board holder, a makiwara, or possibly a reflex bar. If anyone has any other suggestions, feel free to leave a comment!

[@hansen704]

Great video. Is it possible to put evt other things Then vater in the ball

[@martial_life]

@@hansen704 I don’t see why not. You could use antifreeze or maybe a slime mix. It’s also possible to use just air, but it won’t be as heavy or have the same feel

Do you recommend a A3 buoy or an A4 ?

Either really. The only difference is the size of them

Is this a 20" or 50"

This one is a 20” buoy
