Input: [header] How to make a homemade weight set [title] Use a milk jug. [step] Fill a clean, plastic gallon jug with water, sand, rocks, or concrete. Make sure that the jug has a handle; you will use this to complete your exercise reps. <sep> (A) Use the handles to lift and lower the jug like you would any hand weight or dumbbell. [substeps] With milk jug hand weights, you can do bicep curls, tricep exercises, and shoulder raises. (B) You should have at least 4 liters (roughly 50 ml) of water for every pound (240 g) of body weight weight you're taking. [substeps] To make a water bottle, fill the neck of the milk jug with water, then fill it with sand, rock, or concrete. (C) Fill the jug with water and press down firmly on the end of the handle when you're satisfied with the weight. [substeps] To prevent spilling or falling of the jug over time, measure out 1/8 cup (120 ml) of water, then fill the jug with water. (D) Additionally, fill it with sand, like bentonite or limestone. You can also use bricks, or create tunnels that will fit inside of the jug you plan to use.

A
