Here is a highly interesting animated GIF. It demonstrates a wide variety of exercises in an animated format. This serves as an excellent visual guide for the clean execution of a workout.
The animated figure performing the pull-ups (see the third image from the right in the second row from the bottom) appears to be a beginner.
The chin does not quite reach over the pull-up bar. Unfortunately, the designer did not make contact beforehand. Otherwise, the proper pull-up technique could have been explained in detail to ensure a flawless representation.
For informational purposes, all these exercises were featured in the free app 7dailymoves.com, which was available for a time in the App Store and on Google Play.
