How can I effectively perform straight bar bent over rows to target my back muscles?

To effectively perform straight bar bent over rows to target your back muscles, start by standing with your feet shoulder-width apart and holding the barbell with an overhand grip. Bend your knees slightly and hinge at your hips to lean forward, keeping your back straight. Pull the barbell towards your lower chest, squeezing your shoulder blades together at the top of the movement. Lower the barbell back down with control and repeat for the desired number of repetitions. Focus on engaging your back muscles throughout the exercise for maximum effectiveness.
