Hi, My son looking for a free standing bag for workout. And after searching for hours on TH-cam I found your channel and I am very impress how easy and efficient you created this reflex punch bag. Thank you so much for teaching us 😊
Thank you for watching! 😀👍
Maaannnn this is great! I kept breaking my everlast and hyper flex reflex bag and got upset spending so much money on replacing them so I tried this out with a little different modifications and boom it’s working like a champ even faster then the expensive ones I already bought for way cheaper 🙏🏼 thank you
You’re most welcome 🙏
Impressive and creative Haha awesome stuff! Thanks for sharing and I'm definitely subbed and glad I came across your page this late night. Thank you so much. I Can't wait to see the body version. I love seeing your building evolutions. This was fun and you got me on a journey now. Thanks again my man.
You’re most welcome! Here’s the full body one in case you missed it: th-cam.com/video/uzBdTSSqAc8/w-d-xo.html

Glad you enjoy it!
Looks awesome!!
hey, thanks for this and other videos... in times like this this is really great way to make your own equipment for exercise...
You’re most welcome
i subscribe, because these DIY things that cost next to nothing compared to the arm and leg they charge for the real stuff that not every one can afford. thank you
You’re most welcome 🤙
I've subscribed purely based on how simply you break down each build. Brilliant ideas and for someone like me who doesnt have an ounce of DIY in me, i dont find any of the builds daunting.
Thanks mate
Any chance of a freestanding tyre heavy bag tutorial?
I love all your tutorials, it really helps me, thank you very much,.. all i can do is to subscribe to your channel. ❤❤🤜🤛
That IS so good!!

Nice job bro
Thanks bro!!!
Who’s watching this in Quarantine?
Keep it up
Thanks - i will for sure!!!
Thank you for posting! This is great. I’ve been trying to work out a version of this with a bit less give so that I can kick it. I was thinking to use a thicker pipe and wrap with foam. Would a 3in (75mm) PVC pipe work or would it take away all of the give/spring? Since the base will need to be really heavy would a tire/concrete base would work? Thinking to attach a threaded adapter to the pipe and set other threaded price in the concrete (about 6in deep) so I can screw and unscrew base. Do you think PVC can withstand a kick without cracking at the point where it’s connected to the bass?
You’re most welcome. The size I use in this video took quite a lot of testing and seems to be the ideal size for a heavy ball like a basketball. Any thicker results in too much speed- not practical. You could possibly combine a thicker pipe with a thinner one like I did in my vey first design: th-cam.com/video/UnKfsPsTAz4/w-d-xo.html
Okay. Thanks! I guess I was hoping a bigger pipe would move and bend a lot less. Is there anyway to get it to move less - be slower and more stable? I’m more interested in power than speed. Thanks again!
Also, I’m going to be making a body for this bag next for body blows. Not sure about kicks but will test.
Great video thanks you.
# I have some questions;
1. The piece you added with funnel which attaches to the pole, is it possible to go over this bit more slowly or show the sequence of which pieces need to be added.
2. Is it possible to provide links to size of funnel and black attachment bit you used for pole. Giving online links, Amazon etc.. will allow us to see exactly what you used.
Thanks you, videos are great. Keep it up and lookforard to rest of your videos.
You’re most welcome 😃 I’ll put together detailed written instructions with the list of items soon. Stay tuned!
@@Kewlus That's great, appreciate that bro. Take care and look forward to your next video
I’m not a fan of the platform but I think I’ll give this a go
Hey dude!! I really enjoy your videos, definetly great ideas 👌🏻 this heavy one is probably my favourite, i might try it. But there is one thing that concerns me. Does the ball hold on just with the rubber thingy, tape and the funnel?
Thanks for for sharing your ideas!!! 🙌🏻👌🏻👏🏼
Yes it does. To ensure the tape grips the ball well make sure to sand the ball like I did in the video
Cheers man. Ya I noticed that you sanded it. I might give it a try then. By the way, guess you know it already but just in case. Small tip, if you fill the bottles with sand + water you will get more weight per bottle 😉
Thank you for the tip. Didn’t know but now I do 🤙
this honestly looks like it works better than all the $400 reflex bags ive found... I’m almost done with my build, but I cant seem to find any 40mm pan cones in my area :( what would you recommend as a replacement?
You can also use a plunger, but cut away the rubber skirt so it sits flush on the ball. Alternatively any rubber pipe gasket that fits onto the PVC pipe should also work. Good luck 🤙
Would that work, putting the rod inside an umbrella base, then the PVC attached like you did? I really want to try this. Your DYI videos are AWESOME!
Thank you brother!!! Yeah should work. Next I’ll be testing different mast materials like fibreglass fishing rods to see what works best. Stay tuned bro!!!
@@Kewlus I got one of your builds finished, somewhat. I tried the pool noodles on the thicker PVC but it's not got the awesome action that yours does with the basetball. I think I will take off the pool noodles as they are almost too light on their own and add the basketball. Awesome work mate, I appreciate your help. I've had reflex bags for a long time but they are super slow compared to a double end bag, etc.. Your builds are super close, and about $270 cheaper than a Cobra reflex bag. You've saved me a lot of money. Great stuff Reedy. I've shared some of your stuff with some pro boxers here in the states. THey said that is pretty damn cool! lol
Thank you brother 🙏 More Cobra prototyping coming! I have some surprises to come on that. Stay tuned!!!
Sorry i didn't get what you put to speed up the bag at the end of the video? Rod?
The steel pipe that screws into the flange - changing the length of that pipe changes the speed.
Thanks what is the type if tape you used to hold the ball. Seems like tape wouldnt hold that ball for long
It’s Gorilla tape. Very sticky and doesn’t come off easily
@@Kewlus cool thanks I want to make this bag I just cant find a pan cone anywhere I cold a plumbing place and they never heard of one and a funnel with a wide enough valve most just go from skinny to wide at base. I could easily make the cobra bag but I think I will prefer this cause it will be a much more intense workout on the muscles. Your videos are awesome
Thank you. Instead of a pan cone you could use a plunger and cut off most of the cone just leaving about a 1/2 inch round the base so that it sits flush on the ball
Can you do a glove tutorial
Do you mean how to make boxing gloves?
@@Kewlus nvm I saw your video thanks
How long do they usually last ? Does the pvc and up breaking after a while ?
Yeah I found the PVC lasts just a few months if used daily. Instead I’d recommend using fibreglass like a fishing rod th-cam.com/video/3Bxnf90AyLU/w-d-xo.html or tent pole th-cam.com/video/D0XXoV7cp-o/w-d-xo.html
Cool thanks man, I'll be making a few different ones. Thanks for all the awesome diy vids !
Im from Brazil and gonna try It...
Good luck bro! 👍
Great! Gotta say your building skills look way better than your boxing lol
Thanks 😏
When I throw a jab punch, how do I move a fist, is there a specific finger to move it original? They are all moving, I'm very confused
Aim to punch with the middle knuckle
@@Kewlus Thank you
the bolts holding the flange to the mdf ripped right out of the mdf. will try mounting to concrete next.
Use large washers on the back of the board 👍
@@Kewlus Flat washer??
Yep
First here 🔥 vid
Legend!
Hi. This pvc pipe fiberglass plastic pipe? Sorry my english, i from hungary. Thanks
PVC pipe is made from tough plastic
@@Kewlus okay.. I`m go tomorrow and buy all ingredient. Thanks for everything.
You’re most welcome! Good luck 🤙⭐️
What is that a stand and what it is called
I use an MDF or particle board to make the stand, so I guess it’s called an MDF stand
@@Kewlus
Where to buy it sir
Hardware stores should have boards like that
Put sand inside and enjoy a Big Mace (Gada) ;)
made this. unfortunately the PVC pipe broke in my base. :( looks like I'm gonna make the one w/ the spring.
😧 that’s odd. I’ve never had a PVC pipe break and I go very hard smashing it. How long was your steel pipe at the base?
Likely your base steel pipe was too short- use a longer base steel pipe and just get another PVC pipe. PVC pipes are cheap. Springs and steel pipes are more expensive
Oh wow! Thanks for the reply back! Big fan, and you're seriously inspiring me! I think that's where I messed up. I didn't have a steel pipe at the base. It was just the PVC pipe. Haha
But now, I know what to do. But I actually just watched the latest upload. I know what I'm gonna do now. USE A FLANGE! Keep up with the great content!
Good luck 👌👍🤞
❤❤💪🇲🇦
Ha ha you are sick bro
Thanks bro 🤙
