Close Grip Bench Press cluster set with the Elitefts Shoulder Saver Bar has some very distinct advantages.  From a bio-mechanical perspective, the Shoulder Saver Bar helps keep unwanted stress off the shoulders, elbows and wrists by slightly limiting the range of motion.  From a logistical perspective, it can be replace low board presses without needing a partner and adds consistency to each rep.  In addition, cluster sets extend the total time under tension by allowing short rest periods within the set itself.
