Grip a pair of rings or similar hanging from a pull-up bar. Keeping your body rigidly extended straight, lean back from the rings to arms’ length, and then pull your body up as far as possible, squeezing the shoulder blades back together and down. Lower under control.
 
Notes
The higher the rings and more upright the body, the easier the movement.
 
Purpose
The ring row is essentially the horizontal pulling equivalent to a modified pull-up—it can be used for high rep training for the back and arms and as an adjustable progression to more challenging rowing work, such as a fully horizontal inverted row. Using rings allows the arms and shoulders to move more freely to accommodate orthopedic issues or limitations, and improves side to side strength symmetry.
 
Programming
Generally sets of 5-20 reps are appropriate.
