Difficulty: Easy
Instructions
Things You'll Need:
- Milk jug Water or sand Duct tape
-
Step 1
Drink the milk. Milk has protein which you need to build muscle.
-
Step 2
Fill the empty milk jug with water or sand. A full gallon of water weighs about 8 pounds. While this is a fine weight to start with, you may want a heavier ball, in which case the sand will be better.
-
Step 3
Tape the cap securely on the jug.
-
Step 4
Substitute a volleyball, basketball or soccer ball for the milk jug to make a more durable---but more expensive---ball. You can either pull the air plug out with needle-nosed pliers and fill the ball with sand or water and replace the plug, or cut a slit in the ball and fill that way, taping securely.
