Lie back on a decline bench with your feet secured and grip a barbell overhead with a slight bend in the elbows. Slowly lower the barbell in a controlled arc behind your head until you feel a stretch in your lats and chest, then pull it back up over your chest using your back and chest muscles. Keep the motion smooth and avoid letting the weight drop too quickly.
Log your barbell decline bent arm pullover sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
