ZULUL WARRIAS PREPARING FOR ACTION
In Africa, you don't sound African, where in Africa bra.im from South Africa, we never say we are from Africa, only outsiders say that. 😈😆
Look up Kulbila_Fitness on instagram.
Thanks, you inspired me to make my own dumbbells.
Pro Tip: Instead of cutting the bucket when you demold. Add some baby oil in the buckets before pouring the concrete in. Then lightly tap around the bucket when it comes time to demold, it will slide off so you can use it again. This will greatly reduce your cost basis.
Hey!! The reason I didn't use a release agent on the buckets was that I didn't want the dumbbells to be smooth. This is why I mixed the concrete in the original container. Closer to the end you can see a few closeups, and the sides look scratched up and more rugged which I think is a much cooler look than a smooth cast of a brand new bucket. Those same scratches and ridges make it extremely difficult if not impossible to demold without destroying the container.
Motor oil works also
WD40 too
I will have to try this then, cause apparently everyone is buying these disposable buckets out.
I recommend Vaseline because it won't run like baby oil.
ProTip. Spray your containers with silicone spray or cooking spray and you can re-use them multiple times
I recently did some kettlebells, great video 🙌🏼
Thanks for ProTip bro. You save me some bucket.
comment takeaways:
--If your worried about pvc pipe breaking with extreme weight... and dont have the tools to use EMT conduits (drill holes)... just get schedule 80 pvc pipe. most hardware stores will carry that too. schedule 40 is weaker than schedule 80.... albeit schedule 40 should be strong enough already aswell.
--Concrete in pvc tube wont make it stronger!!!
--Spray outside of finished concrete dumbbells with Line-X a few times and they will be much stronger
--Use hockey grip tape to wrap handles, electrical tape will come off after just one sweaty sessions
You basically summed it up :)
If you put some nails and concrete on that pipe it will make it stronger I believe but thanks for your insight
do you think a 3/4 inch emt conduit will be strong enough. Home Depot has 1 inch x 10 ft. but I dont need all of that to make a pair
D H depends on the weight. I would think up to 35lbs should be fine. I’m thinking of making 45 lbs in 1”
can schedule 80 handle 50 lb concrete dumbbells? If i stick the schedule 80 pvc pipe into the bucket of concrete I don't need to drill holes in and put screws in?
An old bro of mine works for a concrete and masonry company and he made his own dumbbells out of concrete, too, but they were all odd weights when he cast them. Each set weighs the same i.e. a 6.1 lbs set, a 13.7 lbs set, a 19.4 lbs set, etc, but, instead of marking the weird weights by their actual weights, he just labeled them #1, #2, #3, #4, etc, etc, in order of lightest to heaviest.
as you cant tell the bigger ones are heavier...
@@andreysilva8418 LoL
that's fucking hilarious
tbh that's just more efficient, the exact weight doesn't really matter (and if it does you can always go check your strength in a gym with proper dumbbells)
I have watched a ton of these and this is by far the best. Your instructions are clear and precise and the video matches. This is the first video i have seen to explain that concrete doesn't reach it's full strength for 30 days. Nice to see a small biz able to pivot amid the chaos, stay nimble!!!
Thanks for the feedback, I'm glad it was helpful!
Thank you for making this video, mate. Concrete and Masonry and anything related has fascinated me for the longest time.
Very interesting and informative. Yes you are very right about pandemic times and the prices of dumbells just exploded. That's actually a pretty smart idea to create own gym. Thanks a lot.
This is great! Thank you. I'm setting up my own garage gym but ain't paying $50 for a dumbell.
Happy to help!
If you dont cut the bucket all the way off, just cut the excess, you essentually have a rubber coated dumbell. You can also get some rubber paint for the outside if you dont like the bucket look.
Also, I would reccoment hockey tape over electrical tape. E tape will slide over time and youll get a greasy residue. Hockey tape is meant to be handled often and feels better on the hands.
This is a great video! I have been watching concrete dumbbell videos and this one was simple and easy to follow.
Awesome! Thank you!
You are a genius, bro! I too have noticed pricing on weights is now ridiculous. Much better to make your own. Great job! 👍
Yes the killuminatii want to Have heart attacks from their covid moonshots because we've spent all out food money on overpriced weights
Another pro tip you could add is to buy rubber coating spray paint to protect the concrete and make them last a bit longer :)
15 push ups(on dumbells) - 20 squats - 20 - lunges - 15 row - 15 narrew push ups(on dumbbells) 15 cheat curls - 15 glute bridge - 30sec dumbbell hollow hold flutter kicks repeat 3x beginner 5xnormal 8x extreem :D love the video:D
This is awesome!! 👏🏾 im gonna try cos here in Samoa it's so expensive but this is so easy and I can get the stuff to make it now im excited!! Thanks for sharing 🙏🏽
These look insane, good job.
They're so beautiful!
Are you taking orders? I want to open a gym. I can call it Flintstones. Seriously though, a great idea.
That is a great a idea not gonna lie, very clever
THATS A MILLION DOLLAR IDEA WHY WOULD YOU POST IT IN A UA-cam COMMENT😂😂
A tally not a bad idea. Hahaha you could go themed and get real creative with that.
Seriously, can we just order some for cheap from you
I was in the process of stealing ur business plan and putting into work since it was going to be very cheap i decided to intelligent plan for all types of licenses tho u will not be able to use them for liability issues 🙃
This is genius!!! Thank you for sharing. 👏🏾👏🏾☺️
I already have my own gym with concrete plates.,dumbells,wooden benchpress... your vid also great🖤👍🏻
Good video. Thanks. Leaving the plastic buckets on it could also work as a protection to the fragile concrete. Cheers
you did a perfect job, I used schedule 80 PVC because its stronger and I used screws but doesn't really matter. I bought liquid plastic to rubberize the concrete but honestly duct tape works great and if you accidentally drop them it'll break or chip but its covered with tape. Liquid plastic will get expensive. My first set looks like shit but I'm improving. Im gonna try to make fixed small barbells with rotors.
Thanks! a great way to make them indestructible without making them look ugly is coating the concrete with LINE-X. Just remember to wait for all the moisture to leave the concrete before spraying (3-4 days)
I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm-neither hot nor cold-I am about to spit you out of my mouth. You say, ‘I am rich; I have acquired wealth and do not need a thing.’ But you do not realize that you are wretched, pitiful, poor, blind and naked. I counsel you to buy from me gold refined in the fire, so you can become rich; and white clothes to wear, so you can cover your shameful nakedness; and salve to put on your eyes, so you can see. (Revelation 3:15-18) you cannot live for this world and not try to stop sinning (being cold) and only believing in God(hot) without turning from sin or sinning and saying God will forgive you after or not read the Bible, pray, worship/obeying God. Which is being a lukewarm. If we are neither cold or hot, God will spit us out his mouth.
Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders 10nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 1 Corinthians 6:9-10
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. John 3:16
Proverbs 11:2 “When pride comes, then comes disgrace, but with humility comes wisdom. ” Proverbs 16:5 “The LORD detests all the proud of heart. Be sure of this: They will not go unpunished. Proverbs 16:18 “Pride goes before destruction, and a haughty spirit before before a fall.
Genesis 1:26-27 - “Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.
Jesus is coming back soon!! Repent and believe!! Jesus loves you and wants a relationship with you 🫶🏽
Plis read revelation 3:15-18 on google if you don’t have a Bible.
(Exodus 20:7) You shall not invoke the name of the LORD, your God, in vain. Please don’t use Gods name in vain, it’s dangerous
Has a nation ever changed its gods? (Yet they are not gods at all.) But my people have exchanged their glorious God for worthless idols. Jeremiah 2:11) having idols of any kind isn’t good 🙅♀️
Shall a man make gods unto himself, and they are no gods? Therefore, behold, I will this once cause them to know, I will cause them to know mine hand and my might; and they shall know that my name is The LORD. (Jeremiah 16:20)
HAVING IDOLS IS A SIN JEREMIAH
16:20 , JEREMIAH 2:11
Revelation 3:15-18 explains that we can’t be cold and hot at the same time which is being a lukewarm. In other words, if we are hot, which is really repenting and turning from sin) if we are cold we just completely don’t really follow God. If we mix those together it makes a lukewarm which they will be spat out Gods mouth and won’t inherit the kingdom of heaven.
For God so loved the world that he gave his one and only Son,that whoever believes in him shall not perish but have eternal life.John 3:16. Greater love has no one than this: to lay down one’s life for one’s friends. John 15:13
Romans 8:38-39 .. John 3:16 .. Revelation 3:15-18 Corinthians 6:9.. John 15:13 Psalms 23:4
Psalms 23:4 || Yea, though I walk through The Valley of the shadow of death, I will fear no evil: for thou art with me;
rod and thy staff they comfort me.
Deuteronomy 31:8. The Lord himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged.
Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus. Philippians 4:6-7
JESUS IS COMING BACK SOON!!REPENT BEFORE ITS TOO LATE!!🫶🏽🫶🏽 ✝️❣️…😊😊
So Boss thanks for the video Its great. As I was watching it at the point that you cut the buckets of the concrete I was anticipating what you said later on about not throwing them around as they will break up. As a person who works with up cycled HDPE plastic a lot I was thinking that you might try to de mold them with out cutting the buckets, then after letting them cure and get all the moisture out you could Remove the upper rim of the bucket and put the buckets back on them and then using a hair drier you can soften the plastic and form it over and around the concrete to enclose them and extend their shelf life a bit. Thanks again for the video, stay safe
Great tutorial! Very helpful - I think I might try this just for fun with a couple 30 pounders. THANKS!
Good luck!
This is pretty awesome. My dad long ago told me how he made his own weights in Puerto Rico now I'm gonna be doing the same
here i am, at 5am watching a video about making dumbbells *sigh*
As long as you get up the next day and make em, nothing to worry about! 💪😎
Thank you so much, so excited to try and make these! 😎
wow! love this video, good job man!
Great idea. One thing you will eventually regret, is the electrical tape on the bar. Speaking from experience here. Eventually, the tape will start to slide around slightly, just enough to expose the adhesive. This then leads to a sticky mess on your bar.
This is a great video. weights are way too expensive so I'm planning on making my own and have watched many videos on how to do it.
Since the buckets are getting cut up anyway, I just thought I'd recomend your local dollar store. I found some that are pretty much the same size at my local Dollar Tree. Even some square pots, which was tempting to try so that they don't roll around. Saves a few bucks.
I just used a 160mm ppr water pipe and it works great and i mixed white cement with gravel mix and its hard as a rock
Instead of containers i used 7 liter water bottle cut in half
This is really cute, I have made this but it took so long to dry it almost takes 3 days, I think it's because of the humidity of my weather that makes it longer to dry. And I decided to paint the Dumbless with colors to make them look even cooler! Thank you
What kind of paint did you use and how is it holding up? You posted this 8 months ago.
Can u give us any updates???
C'mon it's been a year
To add more strength to dumbbell you can add wire mesh to it.
How would you do that?
Your videos are the best man.. keep up.. your the best..
That's awesome! I'm going to try and make some of these.
Good luck!!
Very cool. I was thinking of spraying the concrete (once it cures) with plastidip.I also have some grip tape I got off amazon (same type used on handle bars and tennis rackets).
You can see how much eforrt you put.
Would love love to see ,how to make barbell
GAS PIPE . FORGET plaSTIC
I just got the same idea :) Thanks for the kinda instruction!
Beautiful Work! Real Deal!
I used crisco in the bucket. Worked like a charm to slide out the weight to reuse the bucket and smells just like cookies 😂
Easier : Drill 2 large drywall screws on each end of the pipe, similar to the nails you placed . let the screws stick out at least 3/4 inch from each side. Pipe will never move. I recommend putting chicken wire in the concrete, in case the dumbbell drops , the wires make it 50 times stronger against cracking.
excellent quality tw congratulations you are super, my question to give it different weight has levels inside the mold or are different molds, where you bought it I would like to acquire it
Really enjoyed watching this video 😁.
Thank you for the guide daniel radcliffe
Wow that was nice... Hope i can make a perfect one like this
Thanks :)
Great video man, gyms still not open in NY, crazy. What size container would I need for a 25lb dumbell? Is there a way to calculate how much concrete? Thanks for posting !!
Love this bro!👌 thanks very much!! & stay safe💪
Thanks, you too man :)
Instead of nails you can also use a bolt and use two bolt-nuts to position the PVC pipe exactly where you want it.
That was the original plan but these nails ended up being cheaper :)
What’s the container size for the 10s 15s and 25s ? much needed is thanks!
Dude that’s really impressive
Thanks!!
Wow I love this... I'll have mine done in no time
Hello your dumbells look perfect! I'm trying this too, thanks for the explanation. Just a question though, if I want 30lb dumbells I just have to measure 15 lbs of dry concrete on each side? The weight of the concrete doesn't change with the matter state?
Thanks! Technically it will be a little bit heavier but its unnoticeable. Maybe by a few grams
@@GlobMarble thank you for the answer!
@mr system yes I did
asys t How did it go?
@@angelayala7922 he was pressing it then one block land on his head
hey if you somehow can make a rubbery seal around it, then that makes them much less susceptible to cracking!
I just used plastic bags and then an extremely large amount of duct tape to pretty good effect. My weights were made of 'Portland cement' (plaster of Paris plus sand) which is weaker than normal cement but I don't baby them and they haven't broken yet after a year or so, the thick duct tape layer seems to work pretty well for protecting them. Ugly but functional :)
you are sooooo creative and talented!!!!!!
Thanks! :)
i love you man
for real ❤️
Looks sweet! Can’t wait to try it out. Do you know where I can get good concrete mix?
Thanks! Any home depot or Lowes location
home depot has it for $4.20 I bought the high strength mixture I'm gonna build this tmrw can't wait
Hi great vid, thanks !
Just a quick question : How much did the finished unit weigh when it dried and how much water did you add in total for each unit ?
For reference the min. water to cement ratio is 0.23:1 just for hydration ( the chemical reaction of hardening ), and 0.35:1 for a more workable mix. This doesn't include the aggregates like sand and stones.
You can add up to 0.5 but after that the concrete strength will be affected so they might break more easily.
You can mix only the water and cement together first, to make sure you get the water and cement mixing properly so that it will harden right, and then mix the aggregates in later.
It will be a pretty stiff mix though.
Thanks for the vid
Thanks , your video helped me to make these weights at home and save some money. Instead of cutting the bucket you can use M-oil and use hair dryer also
very nice video dude! amazing work! thanks a lot
Glad you liked it!
Worked out well! I’m gonna have to check out your other concrete work.
I’m thinking of buying a gallon of flex seal and dipping the weights in it.
@$30 a gallon I’m still waaaaaay ahead of buying a set of 25’s
Plus it may keep it from chipping etc
We’ll see.
That's a great idea, I never knew flex seal was so cheap
Where do you get flex seal at that price?
I erred
That was 32oz can for $30
Oh well.
@@bodiddley7404 oh man .... I was so looking forward to it.
@@bodiddley7404 look for liquid plasti-dip instead of flex seal. plasti-dip is usually sold in spray cans, but the liquid form might work better for this. typically people use the liquid kind to dip tool handles to add a rubber like grip to them, but I dont see why it wouldnt work on these weights if you completely encased the concrete in it.
this is so cool! i was just thinking about making some of my own
Thanks!
I'm about to do this too! .DIY is cheaper and fun.Someone said use rubberized undercoat to keep the chips to a minimum when done.And reuse the molds by using Silicon lubricant.I was thinking of using lead weights and shove them inside the cement and to unbalance the weights as not to roll away and makes the wrist stronger by using the weights gripping differently.
Amazing video, really inspired me for what I am planning to do
Thanks man, good luck!!
You have a bosnian surname and not bosnian name.
Thank you so much for this video! I just bought the materials for this here in Portugal! I'd like to keep the buckets though, so how do I go about it? What oil do I add and when during this process?
You need to add a release agent like oil to stop the plastic from bonding to the concrete. Also the main reason I had to cut them out was because I mixed the concrete in the same bucket which I casted in. This created a bunch of scratches inside my buckets which gripped onto the concrete. Instead you should do all of your mixing in a separate "mixing bucket" and pour it into a fresh casting bucket to reuse them :)
How do you get accurate weight measurements? What kind of scale do you use
Dude, its a dumbbell, not a laboratory standard. Close enough is good enough. :)
@@tonydiethelm8980 yeah you’re muscles won’t notice the 0.5lbs difference lol
Brilliant idea... Im after more weights.. for weighted dips it's just making sure I get the right formula to make sure the weight is right. Is there a rough guide for working out what weight you want...?
Great job, I’ll give this a go.
Thanks man I’m gonna make some weights are 4-6$ a lbs where I am rn
No problem! :)
( 4:50 ) spray the mold with PAM or any other cooking oil and reuse them
You can get it out without oil. Plastic wont stick to concrete. I had to break it because of the ridges and scratches from mixing inside the bucket. No release agent would help in demolding them
@@GlobMarble Couldn't you just pour the mixed cement into the molds to reuse them, and designate a container for mixing?
truck bed liner spray works great on giving the concrete a nice nonslip surface- and also protects the surface! just a thought!
This was a very helpful video. Thank you.
Glad it was helpful!
Apply oil layer inside of the container. Then you can easily remove the container without braking..
When do I apply it during this process?
@@miguelbotto2849 before fill concret , apply oil inside of the container .
Heat up the nails and push them through instead of heating the pipe.
quick question, I honestly don't know who to ask about concrete stuff, but is it better if I use large metal screws instead of the metal nails he used because it gives it more surface area or will that weaken the dumbbell
Nails that huge have a lot of thermal capacity he did it right
You would waste a lot more gas doing it that way tho

Thank you so much for sharing this!!!
You're welcome!
Epic that Going to try it soon
If I want the weight on one side of the cement block to be 20 pound, does that mean I only mix 20 pound of cement with water? thanks
Take approximately 19 pounds of cement and 1 litre of water
@@yashkelaskar8943 1 liter of water weighs 2.2 lbs.
@@mckenziekeith7434 thats why he said approximately
@@yashkelaskar8943 I thought the water would evaporate and eventually 19 pound of cement + 1 litre of water would weight 19 pounds.
Make sure to mix only half since you'll be curing one side at a time.
It's 2 AM and I'm watching how to make dumbbell at home ........
Very cool idea, thanks for sharing!
Thank you :)
Hey just thought I'd clarify that the water doesn't evaporate from the concrete, it sets with it to form the hydrates that give it strength. The weight of the water needs to be accounted for in the final weight of the dumbell.
If i were to do this how heavy could i go? Would the pipe break during a workout if were to cast a 40lb dumbbell?
I doubt it, I have a 35 lb one, but to be on the safe side you can use EMT Conduit instead of pvc :)
@@GlobMarble would steel pipe work?
@@GlobMarble thank you
@@python9657 I was thinking the same thing but he didn't reply. I would like to know myself cause it should be a lot better than the PVC.
What do I do if I don’t have a drill?
Easy! Get much thinner nails, but still long enough to almost stretch the whole distance of the bucket. Use a hammer to nail them in. You will need much more nails, closer to 12 nails for one bar instead of 4.
@@GlobMarble just take a cutting player to hold the nail and heat it till hot and insert it, it will slice in like butter, immediately pour water too cool it... Problem fixed...
lovely home made dumbells mate
Thanks!!
Great video bro, but you also can re-use the bucket mold putting engine oil burned inside the bucket before adding the concrete mix and then when concrete is cured, just pop up the bucket without cutting it off
Just use EMT Conduit instead of PVC it's a lot safer and more sturdy!
Maybe so! Still, I haven't had any problems with mine yet :)
It would be interesting if you left the bucket on somehow, trimmed it and left them “plastic encased”.
@@garnetsteen that would be a great idea
i like the idea but can u get the nail to fit in as tightly? or would that be a none issue with it being in concrete?
Might as well go rigid conduit so you never have to worry
6:57 are those numbers in lbs or Kg ?
Lbs
I love this. I'm going to make mine 🙏
I made this after seeing your video works great
Great!! if you like to drop weights after using them, you can give it a good double coating of flex seal to make these indestructible :)
That's the biggest 35lbs dumbbell I've ever seen
Need How To Tutorial for Thumbnail’s amazingly life like Concrete Cat Sculpture
Add latex concrete additive for more durability/shock absorption. Great vid 👍
Nice....Lots of love from India
As an added bonus, you get to give the finger to “Made in China”.
0:38 So they can fit without touching any corners
... in a round bucket. 😀
lol you got me there :) I meant to say walls
Wow you are awesome 👌 man thanks for sharing 👍 😀
Great great great video!!! Cheers from Amsterdam!
Thanks for watching!
Bro love your stuff
I appreciate that!
Would 90 lb concrete dumbbells be completely unfeasible? How massive would they be?
I love it... I am going to do this.... Thank you so much.
Good luck!!
very cool idea im gonna do this one for sure!
Go for it!
