DIY Kettlebells for under $10

While looking for ways to change up our current workout program, I came across the Russian

Kettlebell. Kettlebells are typically cast iron "cannonballs" with handles. They provide a great, well-

rounded workout for strength training as well fat loss. The only downside to Kettlebells that I could

see was their cost. Expect to pay anywhere between $2-4 / lb. for a Kettlebell. A 20lb Kettlebell will

easily cost you $50.

Looking for an inexpensive option, I ran into an article posted to a CrossFit forum

(http://www.crossfit.com), which provided details on how to build an inexpensive Kettlebell. I have

since built 5 Kettlebells of various weights and have been extremely impressed by the durability of

the product as well as the options we now have when working out at home.

Kettlebell exercises employ a wider range of motion than traditional dumbbells and typically involves

swinging and explosive movements that utilize the full body. Because the weight is off-center fromthe handle, the movements demand greater stability and really target the core muscles.

Step 1: Materials & Tools

Materials:

-1 bag quikrete pre-mixed concrete mix

-1 cheap rubber ball (under $5)

-26" of 3/4" or 1" PVC (sch40)

-Small quantity of sand

-Duct tape

-Water

Tools:

-1 Hacksaw or Jig Saw

-1 Heat Gun or Oven

-1 Bucket (for mixing)

-1 Small Garden Spade or similar tool (for mixing and transferring concrete to the ball)

-1 Pair of Scissors

The handle used for these Kettlebells is made from PVC pipe which has been heated and bent to

form. I have found that 3/4" PVC (sch 40) has been sufficient for smaller weights (10 - 20 lbs.), while

I've opted for 1" PVC for larger weights. To save costs on these builds I've begun using PVC

Conduit (for electrical installations). Originally I had used Plumbing PVC (potable), but found the

PVC Conduit to be at least half the cost of the Potable type.

For sizes & weights, I have found that a mini basketball (Size 3) will end up around 13 lbs. or so,

while a full sized basketball will be just under 30 lbs. You can also adjust the weight of the Kettlebell

by adding in less/more dense items (ie. lead or steel shot or washers, etc to increase the weight, or

packing peanuts or similar to decrease the weight).

Use the hacksaw to cut the PVC to a 26" length. Depending on your preferences you may want a

bigger or smaller handle, but I've found that 26" makes a comfortable sized handle.

Use Duct tape to cover the opening of one end of the PVC.

Fill the PVC pipe with sand.

Once packed full, use Duct Tape to seal the other opening of the PVC.

The sand is used to keep the PVC from losing its roundness when being heated up and shaped.

Forming the Handle

Once the PVC has been filled with sand and sealed with Duct tape, it is ready to be heated and

formed.

There are two options that I've tried and both have worked well. The first is to use a heat gun to heatthe PVC until it is pliable enough to bend and form the handle shape. The other is to use an

oven. With the oven method, I would wrap the PVC with tin-foil, place it on a baking sheet and heat

it at 350F for 10min. After that, the entire length of PVC is soft and ready to be bent.

Whichever method you use to heat the PVC up, you would then either bend it by hand (using oven

mitts for protection) or use a template to wrap the PVC around to create the shape you

want. Ultimately you want the PVC to be shaped like a triangle with nicely rounded corners.

Once the PVC has been bent, you need to keep it in this shape until the PVC cools again. Dipping

the pipe in cool water will help speed this process up.

Once cooled, you have yourself a handle.

NOTE: if you are not happy with the shape of the handle, simply use a heat gun to re-heat the area

of concern and re-shape it again.

With the handle complete, it's time to move on to the ball.

You need to cut the ball open so that the handle can sit half-way inside. The ball is being used as a

form for the concrete as well as a nice rubber coating for the finished Kettlebell.

Cut a slit in the ball long enough to sink the handle to a suitable depth inside the ball. Be sure to

insert the handle as a test to ensure the length of the slit is correct. Once the slit is complete, cut

two (2) circles at both ends of the slit. The PVC pipe will sit within these circles. The slit will then be

used as an opening to fill the ball with concrete and will allow the flaps on both sides to cover up the

concrete on the finished product.

Note:This latest build was for the wife (hence the pink & white ball).

With the ball and PVC handle ready to go, you can move onto the last step: filling the ball and

inserting the handle.

Pour enough Quikrete into your bucket to roughly fill the ball. Don't worry about being too exact, if

you have a little too much, oh well. If you don't have enough, just mix some more.

Add just enough water (a little at a time) to the bucket and mix until the concrete mixture is a thick

paste. Make sure it isn't too runny. If it is, just add more Quikrete to balance things out again.

Once your Quikrete is mixed to the correct consistency, use a small garden spade or similar tool to

spoon the concrete mixture into the ball.

While you're filling, press down on the ball to create a slight dent in the bottom of the ball, this will

keep the finished Kettlebell flat on the floor and will keep it from rolling around when you set it down.

Once the ball is mostly filled, insert your handle and set it to a comfortable depth.

Continue adding concrete until the ball is full. Make sure to shake the ball and lightly tap it on the

ground to get the concrete settled to the bottom.

Once the ball is filled, check that your handle is still at your desired depth and is also nice and

straight.

Once everything checks out, give the ball a quick wipe with a damp cloth to remove the excessconcrete and let the concrete set for at least 24hrs.

After the 24hr set, wipe your Kettlebell down once more and you're ready to start swinging.
