This is an icon representing exercise and shows a person running to the right. There are four differently sized horizontal lines coming off the back of the runner to show it is traveling.
This Exercise 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 5,700 icons, all in the same style and quality.
