Why Do I Feel Lat Pulldowns in My Biceps

Why You Feel Lat Pulldowns in Your Biceps (It's Not Your Biceps' Fault)

The reason why you feel lat pulldowns in your biceps is almost always the same: your elbows are traveling behind your body, turning a back exercise into a bicep-dominant pull. This common mistake shifts the load from your lats to your arms, meaning your biceps and forearms are doing up to 70% of the work that your back should be doing. You're not alone in this. It’s the single most common frustration with this exercise, and it makes you feel like you're just spinning your wheels, doing endless reps without ever seeing the back development you want. The good news is this is not a strength problem; it's a technique problem. And technique is fixable, starting today. Your biceps are supposed to be involved-they are secondary movers in any pulling motion. But they should feel like helpers, not the hero of the story. If your biceps are screaming by rep 8 and your back feels nothing, your form is broken. We're going to fix it by changing one simple thing about how you think about the movement.

Stop 'Thinking' About Your Lats-Change Your Mechanics Instead

You’ve probably heard the advice to use the “mind-muscle connection” and just “think about your lats.” This is useless advice. It’s like telling someone who can’t swim to “think about floating.” The mind-muscle connection is the *result* of perfect form, not the cause of it. You can’t force a connection to a muscle that isn’t being properly recruited. The real fix is in understanding the mechanics. Your latissimus dorsi (lats) have one primary job in this movement: shoulder adduction, which means bringing your upper arm down and in toward the side of your body. Your biceps’ job is elbow flexion, or bending your arm. If you start the pulldown by thinking “bend my arms and pull the bar to my chest,” your biceps will always take over. They are literally doing the first thing you told your body to do. The fix is to remove your hands and biceps from the equation mentally. Instead of pulling with your hands, you need to drive with your elbows. This mechanical shift forces your lats to initiate the movement. The #1 mistake is initiating the pull by flexing your elbows. The correct way is to initiate by depressing your scapula (pulling your shoulder blades down) and then driving your elbows down towards the floor. This simple change in sequence is the difference between an arm workout and a back workout.

Weeks of perfect form. All in one place.

The 3-Step Protocol to Force Your Lats to Work

This isn't about trying harder; it's about re-learning the movement from scratch. Follow these three steps exactly. Do not skip a step. For the next 3-4 weeks, this is your new lat pulldown. Your numbers will go down, and that is the entire point. We are trading ego for results.

Step 1: The Weight Purge (Drop it by 50%)

Before your next set, look at the weight you're using. Now, cut it in half. If you were pulling 120 pounds, you are now pulling 60. If you were at 80 pounds, you're at 40. This is non-negotiable. You cannot learn new motor patterns when you're struggling against a heavy load. Your brain will default to its old, incorrect pattern (using your biceps) to survive the set. The goal here is not to lift heavy; it's to perform 15 perfect reps where your lats are the primary mover. If you can't do 15 reps with the new, lighter weight without your biceps screaming, drop the weight again. This step is about killing your ego to build your back.

Step 2: The 'Elbows Down' Cue (Forget the Bar)

Your hands are the problem. They are connecting your biceps to the bar. We need to disconnect them mentally. Grip the bar just outside shoulder-width. Now, stop thinking about the bar. The bar doesn't exist. Your new goal is to drive your elbows straight down into the floor, aiming to tuck them into your back pockets. Imagine someone is standing behind you, and you're trying to elbow them in the ribs. This cue forces your lats to engage to pull the arm down. Your hands are just hooks; they are along for the ride. Do not use a death grip. A thumbless grip (wrapping your thumb over the bar with your fingers) can help reinforce this, as it makes it harder to squeeze and pull with your forearms and biceps. Perform a set of 15 reps focusing only on this one thought: "elbows down and back."

Step 3: The Scapular Depression Drill (The First Inch)

This is the secret sauce. Before you bend your arms at all, you're going to pre-activate your lats. Sit at the machine with your arms fully extended, holding the bar with your light weight. Let your shoulders relax and rise up toward your ears. Now, without bending your elbows even a single degree, pull your shoulder blades down. The bar will only move about 1-2 inches. Hold for a second. You should feel a tightening in your armpits and across your upper back. That's your lats turning on. Relax and let your shoulders rise again. Do 5 reps of just this tiny movement. This is a scapular depression. On the 6th rep, perform the scapular depression, and then immediately follow through by driving your elbows down to complete a full lat pulldown. Every single rep of every set from now on will start with this 1-inch movement. This drill teaches your body the correct firing sequence: lats first, arms second.

Your First 'Correct' Set Will Feel Weaker. That's Good.

Get ready for a shock: the first time you do a lat pulldown correctly, it will feel incredibly weak and awkward. The 60 pounds you're using will feel heavier than the 120 you were ego-lifting before. This is the clearest sign that you are finally using the right muscles. Your lats are likely undertrained because your biceps have been doing their job for months or even years.

Week 1-2: Expect a significant drop in weight, around 40-50% of what you used to lift. You will feel soreness in new places, deep in your back and under your armpits. This is a victory. Your biceps will feel strangely fresh. Your job for these two weeks is not to add weight, but to master the form for 3 sets of 12-15 reps. Film yourself from the side to check your elbow path. Are they driving down, or flaring back?

Month 1: By week 3 or 4, the movement will start to feel more natural. You've begun building a new neural pathway. Now, you can start adding weight back, but only in the smallest possible increments, like 2.5 or 5 pounds. The rule is simple: if adding weight causes your biceps to take over again, the weight is too heavy. Drop it back down. Good progress is adding 5 pounds a month while maintaining perfect form.

Month 2-3: The mind-muscle connection you were trying to force before will now appear on its own. You'll be able to feel your lats contract on every rep. The weight you're lifting will start to climb back up, but this time it will be true back strength. You might be lifting 80-90 pounds with perfect form instead of 120 pounds with bad form, but your back will be doing 100% more work. This is how you build a wider, thicker back.

Frequently Asked Questions

Grip Width and Hand Position

A wider grip can theoretically target the outer lats more, but it also provides more leverage for your arms to take over. For learning, start with a medium grip, just slightly outside your shoulders. This provides a strong, stable path for your elbows to travel straight down. Master this grip first before experimenting with wider or narrower options.

Feeling It in Your Forearms

If your forearms are burning, you are gripping the bar too hard. This is a death grip, and it's a sign you're trying to pull with your hands. Loosen your grip significantly. Think of your hands as simple hooks. Using lifting straps can be a useful temporary tool to take your grip out of the equation and let you focus solely on the back mechanics.

Underhand (Supinated) Grip Pulldowns

An underhand or supinated grip (palms facing you) pulldown is a different exercise. It intentionally increases bicep involvement to lift more weight and target the lower lats differently. It is a great compound movement, but it is not the exercise you should use to learn how to isolate and feel your lats. Master the standard overhand pulldown first.

Good Alternatives to Lat Pulldowns

If you continue to struggle, switch exercises for a while to build the connection differently. Straight-arm pulldowns are an excellent isolation exercise that teaches you to engage your lats without bending your arms at all. Assisted pull-ups use the exact same movement pattern but in a closed-chain environment, which some people find more intuitive. Finally, single-arm dumbbell rows allow you to focus on one lat at a time, which can make the connection easier to find.
