Lie back on a flat bench, gripping an EZ bar firmly in both hands. Hands should be narrower than shoulder width. Your arms should be extended directly above you, at a 90 degree angle to your torso and with your palms facing away from you. This is the start position. Keeping your elbows pointed forwards and upper arms still, bend at the elbows and slowly lower the EZ bar towards your head. Inhale as you do this. Reverse the movement and extend your arms back to full extension. Squeeze your triceps as you do this and exhale. Repeat for the required number of reps (or time).
