Adjust seat to put chest in a horizontal line with arms. Grip handles with palms down. Keep shoulder blades squeezed together (retracted) against back pad and maintain position throughout entire exercise. Throughout motion, shoulders form 90 degree angle to body (upper arms are parallel to floor). In a controlled motion, push handles forward to extend arms without locking out elbows. While maintaining the controlled motion, bring elbows back without setting weight down or relaxing the muscle.
