Trouble finding dumbbells? Let's build some DIY Dumbbells out of concrete!
➡ Concrete Dumbbell Molds: bit.ly/3v7m6nW
Dumbbells are a staple in home gyms. But, they take up a lot space, cost a lot to buy and even more to ship. To fix this problem, were going to make concrete dumbbells via a do-it-yourself method. These are a fun project that with a little time and creativity can end up being used for nearly every workout you would use regular dumbbells for. Bench press, curls, and even goblet squats.
Let's do it!

Water First! Makes mixing way easier. Cement is very corrosive wearing gloves is Highly suggested. Concrete burns are not a fun time and can dig nice holes in you skin down to the bone if untreated. If you did end up burning you're hands use a vinegar & water solution to neutralize the alkaline burns.

Here are some protips from my experience: -why buy molds when plastic buckets are so inexpensive, if it breaks, no big deal -on handles, just make some serrations, its way easier and it will hold just fine (same as construction rebar steel) -metal corrodes from sweat, cut some pvc pipes and put it over the handle before making second end of DB -you don't need silicone to tack handles into place, use hot glue (way cheaper) -alternatively, if you make plates for DB/BB, use a round bucket to make plates and use piece of pvc pipe as inner sleeve. -you don't need wire/rebar for for concrete if you mix your own, sand+gravel and cement in 3:1 ratio is hard and strong if cured properly -mix in water carefully little by little until the concrete sticks to your fingers, that's enough water -use (kitchen) digital scale to get accurate weight of mix you put in the mold --if mixed like described, final dry concrete will lose 5-10 percent of the starting weight (water which has not chemically reacted with cement) -different batches of concrete will always lose different amount of water so always make pairs of components from same batch to get even weights -don't do let it dry outside in the cold and wet weeather, concrete will be weak and it will crumble -concrete gives away dust and can chip/crumble so you need to strengthen the surface, use a paintbrush and coat it with sodium silicate solution so that it gets into the surface and let it dryout, cheap solution and works great

@tomislavg9590 3 жыл бұрын

@@ElijahPrivetteRealEstateVlogs For 110lb (50 kg) DB you would definitely need some iron, lead or something like that. If you can get your hands on some solid metal bars (eg. car drive shaft from scrapyard, like I did) to cut handles from it and/or pieces to put into concrete, that's nice addition of weight. Average concrete density I usualy get is only about 2,2 kg/L (far from ideal, of course), dumbell would be simply too big and unusable for anything but perhaps single hand bent over row. If you are making plates for barbell its ok to make larger/bigger diameter plates. About 50lb (20 kg) is max size practical for various exercises (bicep curl, overhead press etc).

Although water does evaporate from concrete mixture during the curing the process since it's an exothermic reaction, it's actually not that much. Coop said to add 49 lbs to get a 45 lb plate, that's so wrong, your mix is way too soupy if that's the case. Most bags recommend using a quart or 2 of water, so 2 lbs of water max. Assuming all the water evaporates (which it doesn't) you'd need 47 lb of wet mix.....I've been messing with my own concrete plates so far and +10-20% water weight seems to be my sweet spot. So use the recommended amount of water (every bag and mix is different), and assume 10-20% of that water weight will evaporate, which is actually pretty negligible. Also I know we're all men, but lime doesn't care and will burn your skin, wear gloves or wash any concrete off your skin pretty fast, use vinegar for any burns that you may get. Lastly, I used my muscle gun to help vibrate the sides of the form, it worked great :D. - A civil engineer

@HickLif3 3 жыл бұрын

If you need them to be more “soupy” there are also additives to make them flow better without compromising the strength if it’s needed but a proper vibe with something like an orbital sander will make it flow pretty well and remove bubbles. For something like this fiber would be better than wire or rebar also

First day impressions:It arrived in a waist high box. kzfaq.infoUgkxP26Tir6n60vUkdtn4mbwhRO8cwuJQNy2 Each dumbbell was in its own foam box within the shipping box. Everything was secure and in good shape. No weird smells. The weight changing mechanism is really smooth and straight forward. Changing weight is really fast and easy. Though the handle is plastic, I don't think it will be breaking anytime soon. So far pretty impressed after my first session with them. I was afraid they were going to be too wide at first, but I didn't have any issues with them while doing upright rows.

I've just found this channel and it's amazing. Just a quick tip. Always clean your tools. When I went to work with my Dad and Uncle in the summer they always emphasised that clean tools are happy tools and they'll last longer as well. Also when concrete goes off the water doesn't evaporate it forms hydrate crystals with the chemicals the concrete is made of. Also Also, make sure to wash your hands because the crystal formation is an exothermic reaction and it can burn you of you leave it on your skin for too long.

Hi there. Great idea and great job. As an fyi, the concrete you mixed with water is wetter than it needs to be. Your cured concrete would be stronger if you had used less water. Another thing that is common with concrete is to use a stick to go up and down in the form to release air and cause the liquid to fully contact the form. Again, I love the idea... Also, if you blew compressed air between the cured concrete and the plastic form the form would likely release with surprising ease.

to get bubbles out you can use a reciprocating saw (adjustable speed one at a low speed is the best) take the blade out and just put the shoe against the side and turn on the saw, the vibrations push the bubbles out quite well, theres also professional vibrating tools that do the same thing but in a pinch recip saw is great

Coop I bought the Stix and Stone oly plate molds after seeing your video months ago. One thing to get exactly the weight you want for your concrete weights is to measure the dry amount of concrete mix. After drying then curing, all water weight is gone so whatever you are left with is just exactly what you pre-measured. Also, I use a fishing scale to weigh the mix + sleeve minus the bucket weight, super handy. We knurl everything!

This will sound weird but a good way to get bubbles out on a smaller concrete form is an old school bullet shaped vibrator with a prophylactic held on with a rubber band to keep it clean. Just turn it on and move it through the concrete for a few seconds at a time. Don’t do it too long or all the aggregate will settle on the bottom. You basically use a much larger version of this setup when pouring and setting larger concrete forms

If you're shopping from the home depot, i highly recommend buying your concrete from them. You need to buy the RAPID SET MORTAR MIX. Not quickrete. It's higher or just as high strength as the high strength quickcrete, but much smoother. It doesn't have as big lumpy stones, it hardens in 1 hour and is strong enough to stand on a 2inch table top mold. You don't need fiber glass or rebar. And when you add the rapid-set "set-control", it'll make it turn into a smooth creamy peanut butter consistency. Which will help it fill in the corners and crevices much finer. I would still use some sort of rebar or mesh or wire or fiberglass or whatever for good measure.

Have you tried the Rock Weights yet? The dumbbells are 40 lbs each as well as their 40 lb kettlebell molds that they have so far with more sizes coming later they say and you just keep the plastic around the cement after you pour the cement from the ends so it seems like they would be a lot easier as well as more durable with the thick plastic staying around the cement and you don't need to worry about the handle being straight or not because it's all part of it and you put a rebar through the handles on the dumbbells which is cool and I think it would help make them stronger as well but I'm just curious if you make the dumbbells and the Kettlebell from them what you think so maybe you can make a video on the Rock weights next possibly if you haven't already?

Buy a 4' piece and hacksaw to 8 inch sections. Third, spray truck bed liner on them when done. Last, i dont bother with release agents... Concrete doesn't really want to stick to plastic... But it probably depends on thickness.

Hey Coop can you do a video about rebranding barbell weight plates with your own logos? I have some branded plates (rubber coated) and I’d like to at the very least paint over the current branding (would black spray paint be a good idea?) and possibly spray my own logo onto them. Not exactly sure what I’m doing here and don’t wanna mess them up

If you're losing ~10% of the wet weight to evaporation, you're going way too wet. The strongest concrete comes from a perfect cement:water ratio, if you hit that you'll have barely any evaporation, but consistency will be horrible. To keep the cement:water ratio low (3:1 is an easy ratio to remember and decently close to ideal, should result in ~3% evaporation, by weight), but still have a workable mixture, you can add some superplasticizer. Only drawback to this is, if you're using a pre-mixed concrete, you may not know your exact cement content. Also, after 7 days of curing, you'll only have reached ~65% of the max strength of the concrete, commonly concrete is considered to have reached "full strength" (~95%) after 28 days.

Possible solution for holding the bar straight as it solidifies: cut a piece of 1/2" plywood the same shape and size as the top of that form (hexagon? couldn't tell from the vid). cut a hold in the exact center the same size as the pipe. cut it in 2 (so you can place around the pipe instead of sliding on it). when you put the pipe in, put the plywood on and tape it in place. between the nipple and the hole it should run square. It could also make lining up the second dumbbell easier if you use heavier plywood. Using medium link chain instead of the wire could also add to the weight if you wanted something heavier. I wonder if you could use epoxy? like a hard epoxy and fill the molds up with chain or something like that. Not sure if you could find an epoxy hard enough, but you could make some wild colors with it thats for sure...

I think that takes too much of the cheap out of this option. I would prob coat it with something like a rubberized coating(Flex seal or similar) or probably even better a cheap spray-on bed liner.

@scottmckinstry1698 3 жыл бұрын

General question - to mimic a rubber coating, couldn't you just spray a few coats of Plasti-Dip? Do you think that would work? Off-hand, I don't see why it wouldn't...
