Position yourself for this exercise by lying back on an incline bench underneath a barbell. Using the same grip width that you would use to perform the standard barbell bench press (a typical width to use creates a 90-degreee angle in the exact middle of the repetition between the forearms and the upper arms), lift the bar off of the rack and hold it directly over your upper chest, ensuring that your arms are locked. To perform the exercise, slowly lower the bar until you feel it touch your upper chest. Pause briefly before bringing the bar back to its starting position by engaging your chest muscles. Repeat this movement for the prescribed number of repetitions before placing the bar back onto the rack.
