You're here trying to figure out how to know if your V taper genetics are bad because you've been training your back and shoulders, but still look more like a rectangle than a V. The answer is a simple math equation: measure your shoulder-to-waist ratio. A ratio of 1.618 is the 'golden' target, but anything over 1.3 creates a noticeable V-taper that is achievable for almost anyone with the right training, regardless of genetics.
You’ve probably spent months doing lat pulldowns and overhead presses, hoping to see that coveted taper appear. When it doesn't, it's easy to blame your parents for giving you wide hips or narrow shoulders. But genetics are rarely the life sentence you think they are. The V-taper is an illusion created by two factors you completely control: the width of your upper back and shoulders, and the circumference of your waist. Your genetics only set the starting point; training dictates the outcome.
Here’s how to do the test right now:
Here’s what the numbers mean:
Your bone structure-your clavicle and hip width-is genetic. You can't change it. But you can build so much muscle on your shoulders that your clavicle width becomes irrelevant. You can build your lats so wide they overshadow your hips. And you can shrink your waist by losing body fat. The problem isn't your bones; it's your plan.
The biggest reason your V-taper isn't showing up has nothing to do with genetics and everything to do with exercise selection. You are likely doing exercises that are actively working against your goal by thickening your waist. A V-taper is an illusion of width up top and narrowness in the middle. If you make both wider, you're just a bigger rectangle.
The number one mistake is treating all back exercises as equal and doing heavy, direct oblique work. For a V-taper, you must prioritize movements that build the upper lats and medial deltoids while avoiding anything that adds size to your waist.
These exercises are sabotaging your V-taper:
Let's look at the math. Imagine you start with 48-inch shoulders and a 34-inch waist (a 1.41 ratio). You train hard for 6 months, adding 2 inches to your shoulders but also 2 inches to your waist from heavy deadlifts and oblique work. Now you're at 50-inch shoulders and a 36-inch waist. Your new ratio is 1.38. You got bigger, but your V-taper got *worse*.
Now, imagine you focused on the right exercises. You add 2 inches to your shoulders and, through diet and avoiding oblique work, drop 2 inches from your waist. You're now at 50-inch shoulders and a 32-inch waist. Your new ratio is 1.56. That is a dramatic, head-turning transformation.
That's the formula: build wide lats and medial delts, and keep your waist tight by avoiding direct oblique work and managing body fat. But knowing this isn't enough. Progress only happens if you track the right lifts and consistently add weight or reps. Can you say for sure what you pulled on your wide-grip pulldowns 4 weeks ago? If you can't, you're not executing the plan, you're just guessing.
Stop guessing and start building. This 12-week specialization program is designed to do one thing: maximize your shoulder-to-waist ratio. It prioritizes high-volume training for the muscles that create width-the upper lats and medial deltoids-while giving you a clear strategy for your midsection. You will train back and shoulders for width twice per week.
The upper lat fibers are what create that 'wingspan' look. To target them, you need to focus on vertical pulling motions with a wide grip.
Wide shoulders are just as important as a wide back. The medial (side) head of the deltoid is what adds pure width to your frame.
Your waist size is determined more by body fat and core bracing than by ab exercises. A smaller waist makes your shoulders and back look exponentially wider.
This isn't an overnight fix. Building a significant V-taper takes consistency and patience. Here’s a realistic timeline of what you should expect if you follow the protocol and diet with 90% consistency.
Weeks 1-4: The Foundation Phase
You won't see dramatic visual changes yet. Instead, you'll feel them. You'll experience intense pumps in your lats and shoulders. Your mind-muscle connection will improve, allowing you to actually feel the target muscles working during each rep. Your strength on the key lifts-pulldowns and lateral raises-should increase by about 10-15%. Your waist may feel tighter from practicing stomach vacuums.
Weeks 5-8: The Noticeable Change Phase
This is where the magic starts. When you look in the mirror, you'll begin to see the outline of your lats flaring out. Shirts will start to feel tighter across your upper back and shoulders. Your shoulder-to-waist ratio, if you re-measure it, will have likely improved by 0.05 to 0.1. For someone starting at 1.2, you could now be at 1.25 or 1.3. The illusion is beginning to take shape.
Weeks 9-12: The Transformation Phase
The changes are now undeniable. Other people may start to notice and comment. Your silhouette has visibly changed. That V-shape is no longer something you have to squint to see; it's there. Your ratio could be up by another 0.1, putting you firmly in the 'noticeable V-taper' category (1.3+). You've now built the foundation and proven to yourself that your 'bad genetics' were never the problem. From here, it's just a matter of continuing the process.
A warning sign: If your waist measurement is increasing, your diet is off. You are eating in a calorie surplus. Re-calculate your needs and tighten up your nutrition. If your lifts are not progressing, you need to increase your intensity, either by adding more weight, more reps, or reducing rest times.
The 'golden ratio' of 1.618 is a classic bodybuilding standard representing peak aesthetics. However, this is an elite goal. A ratio of 1.3 or higher creates a very clear and impressive V-taper that is attainable for most dedicated lifters. Don't fixate on 1.618; focus on improving from your current number.
Having structurally wide hips means you have a slightly bigger challenge, but it does not make a V-taper impossible. It simply means you must be even more dedicated to building a wider back and shoulders to create the desired illusion. You need to maximize your numerator (shoulders) to overcome the larger denominator (hips).
Body fat is critical. For men, a V-taper starts to become clearly visible at around 15% body fat and becomes truly dramatic and sharp below 12%. For women, the effect is noticeable below 22% body fat. You can build a huge back, but if it's covered by a layer of fat that also widens your waist, the effect is lost.
For a specialization phase focused on improving your V-taper, training the lats and shoulders with a focus on width twice per week is ideal. This provides enough stimulus for growth and enough time for recovery. After 12-16 weeks, you can return to a maintenance frequency of once per week.
Deadlifts and heavy barbell rows are phenomenal exercises for building overall back thickness, strength, and power. They are not 'bad' exercises. However, for the specific aesthetic goal of maximizing the V-taper illusion, they should be de-emphasized in favor of wider-grip vertical pulls and targeted shoulder work that don't thicken the waist.
