Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set the rings at chest height, shoulder-width apart or slightly wider. Smoothly push yourself up and make sure you're barely swinging. Lower yourself until your elbows bend to about 90 degrees or slightly more. Smoothly press back up without losing balance. Repeat for the required number of reps.
Try to keep your legs pointing straight down — you'll swing less. If your arms or torso shake, start by simply holding the top position. Even if you already do many reps on parallel bars, start with a small number on the rings to better control the movement.
