The endless debate over the barbell row elbow position tucked in or flared out for a stronger back is solved by one simple concept: a 45-degree elbow angle builds your lats for a wider back, while a 75-degree angle builds your upper back for more thickness. You're not doing the exercise wrong; you're likely doing two different exercises without realizing it. You've probably felt the frustration of pulling 185 pounds but only feeling it in your arms, or finishing three heavy sets and your back doesn't feel worked at all. That confusion ends now. Tucking your elbows isn't inherently 'better' than flaring them. They are just different tools for different jobs. Tucking the elbows close to the body, at roughly a 45-degree angle, creates a line of pull that aligns perfectly with the fibers of your latissimus dorsi (lats). This is the movement that creates back width. Flaring your elbows out, closer to 75 or even 90 degrees, shifts the mechanical advantage to your rhomboids, rear deltoids, and mid-trapezius muscles. This is the movement that builds a thick, dense upper back. The problem is, most people blend the two, ending up with a sloppy 60-degree angle that doesn't effectively target either muscle group and lets the biceps do all the work.
If your biceps are burning out before your back, it's not because they're weak. It's because your form is making them the primary mover. The goal of a row is to pull with your back, using your arms as hooks. When your elbow position is wrong, or the weight is too heavy, your body defaults to the easiest path: bending at the elbow. This turns the row into a glorified, heavy bicep curl. The solution is to think about driving your elbows back, not pulling the bar up. Let's look at the physics. For a lat-focused row, your elbow must travel back and slightly down, staying close to your torso. Imagine you have oranges in your armpits and you're trying to squeeze them. This path forces the lats to contract. For an upper-back-focused row, your elbows must travel up and out, away from your body. Imagine trying to touch your shoulder blades together. This path forces your rhomboids and traps to do the work. Most lifters who can't feel their back are using a weight that's 20-30% too heavy. If you row 205 pounds with a rounded back and a lot of bicep curl, you're not building a 205-pound back. You're building 135-pound biceps and a future injury. The elbow angle dictates everything.
You now understand the physics: a 45-degree angle for lats, 75 degrees for the upper back. But knowing the angle and executing it perfectly for 3 sets of 10 reps are entirely different skills. Can you honestly feel the difference between a 45 and 75-degree flare on your last heavy rep? If you're not tracking the movement pattern and the numbers, you're just guessing.
Stop trying to do one 'perfect' barbell row. Instead, program two different rows on different days or in different training blocks to build a complete back. Here is the exact protocol to follow.
This is your 'width' builder. It targets the lats to create that V-taper look.
This is your 'thickness' builder. It targets the rhomboids, rear delts, and traps to build a dense, powerful-looking upper back.
If you're still feeling it in your arms, implement these two cues immediately.
When you switch to intentional, correct rowing, your numbers will drop. This is not a sign of failure; it's the first sign of success. Here’s what to expect on your journey to building a truly stronger back.
That's the plan. Two distinct rows, specific rep ranges, and a focus on form over weight. You'll track your grip, torso angle, elbow path, reps, and weight for both movements. It's a lot of data for every single back day. The people who build impressive backs don't have better memories; they have a system that removes the guesswork.
An underhand (supinated) grip forces your elbows to stay tucked, which heavily targets the lats. It also involves more bicep, allowing you to lift heavier. The trade-off is higher strain on the bicep tendon. An overhand (pronated) grip is more versatile for targeting either the lats or upper back.
A 45-degree angle is a great starting point for overall back development. A more upright torso shifts focus to the upper traps, while a torso parallel to the floor better isolates the lats and rhomboids by increasing the range of motion. Choose the angle that supports your specific goal.
Lower back pain during rows is almost always due to lifting too heavy and using momentum. Brace your core like you're about to take a punch, keep your spine neutral (no rounding), and lower the weight. If pain persists, switch to a chest-supported row machine to remove the lower back from the equation.
Barbells are king for maximal loading and building overall mass. Dumbbells are superior for increasing range of motion, correcting strength imbalances between your left and right side, and allowing a more natural wrist and elbow path. A good program includes both for complete back development.
For a lat-focused row (tucked elbows), pull to your belly button. For an upper-back-focused row (flared elbows), pull to your lower chest or sternum. Pulling too high often engages the front delts and turns the movement into an awkward upright row, defeating the purpose.
