Floor fly (with barbell)

Lie flat on your back on the floor with your knees bent and feet flat on the ground. Hold a barbell with an overhand grip, arms extended straight up over your chest. Slowly lower the barbell out to the sides, keeping a slight bend in your elbows. Lower the barbell until your arms are parallel to the floor, feeling a stretch in your chest. Pause for a moment, then squeeze your chest muscles to bring the barbell back to the starting position. Repeat for the desired number of repetitions.
