We'll provide you instructions on making a dumbbell set out of empty soda bottles. The bonus to this set is that you can adjust the weight by adding or subtracting contents from the bottles.
2 Liter Soda Bottle x2
1" diameter PVC pipe - 7" long - x2
1" diameter PVC pipe - 8" long - x1
1" PVC coupler- x2
Black spray paint (optional)
Hot glue gun
**It may help to use your PVC piece as a stencil, you will want this pipe to fit snuggly into hole.**

FIY - 1 Liter of sand = 4 lbs
Therefore, 2 full bottles will create about a 16 pound dumbbell.
**If you would like to fill your bottle weights with liquid, you must create an air tight seal in step 6 to avoid leaking. To do this I would recommend replacing the hot glue with Flex Seal.**
Spray painting the bottles will give a cleaner look.
Break a sweat in the comfort of your own home.
**If you need heavier weights, this design allows you to connect a second pair of bottles, using 2 more couplers, onto your dumbbell to add about double to weight**
