There are a few different types of barbell cushions that can be used for a better workout.

These include traditional foam padding, egg-crate style inserts, and air cushions. 

Traditional Foam Padding: This type of padding is the most common and is simply foam that has been placed around the barbell to provide cushioning. It can be made from a variety of materials, including memory foam and latex.

Egg Crate Style Inserts: Egg crate style inserts are similar to traditional foam padding in that they are made from foam and have an insert inside. However, these inserts are shaped like an egg crate, which makes them more comfortable to use.

They are usually made from PVC or polyurethane and can be ordered in different sizes to fit different bars. 

Air Cushions: An air cushion is a type of supine support device that uses compressed air to create pressure against the body. The pressure creates a relief in the muscles above the site of compression, which helps reduce pain and promote healing.

Air cushions come in various sizes and shapes and can be bought separately or as part of an exercise system.
