This video goes along with the Back Workout I posted earlier today.
Underhand Bent Over Cable Rows:
Use a straight bar attachment hooked on a low pulley. Grab the bar with and underhand grip/palms up. Feet are spread wide apart, Knees bent, and bending over at the waist keeping your back straight (not rounded) and head up. Pull the bar towards your abs and squeeze the shoulders blades together.
Close Grip Underhand Pulldowns:
Sit down on a cable pull down machine with a straight bar attached to the pulley. Grab the bar with and underhand grip/palms facing you and hands are closer than shoulder width apart. Pull the bar down touching your upper chest.
