Since we have all been in quarantine for the last few months, not being able to go to the gym and restaurants, I have collected quite a few takeout containers and a few pounds as well. For this build, I wanted to use the containers to make inexpensive weights that I can use in my apartment.

I have been inspired by the use of concrete by Ben Uyeda from Home Made Modern. I like how he combines concrete with simple materials to make useful objects. I also really like the modern look of things built out of concrete.

Supplies

1. Concrete (a bag worth $4 would be more than enough)

2. some pairs of empty take out containers, based on your weight preference

3. some sort of rod/pipe, I've used 3/4 inch dowel rods but a plastic or metal pipe would also work

4. some screws

5. a saw to cut the rod/pipe to length

6. drill bits and a drill to make holes (you can also use thin nails and hammer)

Step 1: Step 1: Cut the Rod/pipes to Length

Cut the wooden dowel or pipe to your preferred length, I used approximately 15-18 inches. around 3-4 inches will go into the concrete on both the sides of the rod so keep enough space for your hands to grip the rod.

Step 2: Step 2: Drill Holes and Put Screws In

Predrill 2-3 holes in the dowels/rods at both the ends of the rods and put in the screws. The screws will help the rod grip the concrete mass. Use screws that are long.

Step 3: Step 3: Prepare Containers for Concrete

Mix in the concrete mix with water as per the quantity on the package, I used the Quikcrete 5000 mix, but any available mix should be fine.

wash or wipe the insides of the containers, If you are going to be using the lids of the containers, cut a hole in the lif for the rod to pass through.

Step 4: Step 4: Pour Concrete

Pour concrete in the container on for one end of the dumbbells, we will pour the other end later. Fill the containers as much as you prefer.

Step 5: Step 5: Put in the Rods in Concrete and Let It Set

Put the wooden dowel vertically into the wet cement, try to keep it in the centre. I used some masking tape to keep the rods vertical while setting. Let the concrete set and cure for 48 hours.

Step 6: Step 6:

After one side of the dumbbells is cured, repeat all the steps for the other side of the dumbbells. Let it cure for 48 hours and then remove the plastic containers. You can also cut the plastic containers out if they are not coming off.

I let the dumbbells sit in water for a few more days so that the concrete can set better
