Idea of Barbell Icon
This icon is a barbell. There is a long, narrow rectangle in the middle. On each side there are two 3d circles, smaller one on the outside and a larger one on the inside. at the very end of the smaller circle is a tiny rectangle, meant to be the end of the barbell poking through the weights.
This Barbell icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,100 icons, all in the same style and quality.
