Veiny arms are not a direct indicator of fitness. However, veins can become more prominent if a person has high muscle mass and low body fat. Weightlifting and other types of resistance training can increase vein visibility in the arms.
Veiny arms are sometimes seen as desirable and an indicator of physical fitness. Good vein health is essential to keep blood circulating through the body. Exercise promotes the appearance of arm veins by increasing the blood flow in your body and lowering body fat.
Visible veins may look cool, but they aren't a reliable sign of health and wellness. Veins start to show when your body fat is in the low single digits, says Poli. "That's leaner than you need to be if your main goal is being healthy."
“Strength training causes the muscles to engorge and swell with plasma,” explains Levison. “This pushes the veins closer to the surface.” It makes them more visible, especially on folks (like me) with pale or thin skin, he says.
Experts believe that veins on arms indicate health and strength and this could be the reason why women find such men attractive.

Bulging hand veins can be perfectly normal, but can be a valid cosmetic concern if their enlarged look bothers you. Sometimes, enlarged hand veins are due to a more serious vein condition, such as varicose veins. It's always a good idea to see your vein doctor about bulging veins in your hands for proper diagnosis.
Bigger muscles require more blood
"When you accrue significant muscle mass, your body adapts by expanding its blood flow network; thus, veins become more prominent in specific areas." This means the more muscle mass you have, the more vascular you'll appear.
These veins are often desirable because they come along with low body fat and well-defined muscles. Veiny arms can also be caused by increased blood pressure, high stress levels, genetics, and age.
As you get in shape, your muscles become more defined and you lose some of your subcutaneous fat. Both of these changes may make your veins more visible. You may also notice your veins more if you have fair skin or as you age. In these cases, the visible veins are most likely healthy.
Prominent veins – known as 'vascularity' – is an aesthetic that's prized by many bodybuilders, but it has nothing to do with muscle size. Most of the effect is down to the dramatic reduction in subcutaneous fat, which makes the skin appear paper-thin and almost transparent.
Low Body Fat
One benign reason a person's hand veins or arm veins might bulge under the skin is because they have very little body fat. Another reason for those bulging hand veins or arm veins might be that a person lifts weights.
Getting Lean and Building Muscle
Your veins start to show when your body is at around 10 percent body fat. But, to maximize vein expulsion, your body fat should be below 8 percent.
This bulging is neither good nor bad but simply a result of normal physiological mechanisms that result from the rise in arterial blood pressure during exertion.
Everyones body is different, so yours may show up at a lower/higher body fat percentage, but I found personally mine popped up at about 14% body fat when I was losing weight and a few of my buddies' came up around the same time. Doing weights and cardiovascular exercise will surely make it show more prominently.
Bulging hand veins are not pathological – in fact, everyone has bulging hand veins. These veins are not like varicose veins in the legs; they are quite normal. However, for some people, they can be very unsightly.
Vascularity refers to highly visible and prominent veins that appear to 'pop out' from the skin. The skin can look thinner, and as though it is wrapped tightly around the veins. Vascularity is the result of low levels of fat and high muscle pressure. It is common among bodybuilders and men who work out at high levels.
Your veins—which have thin walls and dilate easily—pump the blood back toward your heart. “The venous outflow is slower than arterial inflow, causing a back-up of venous blood causing higher pressure in the veins," says Doug McGuff, M.D., author of Body By Science. That increases pressure causes the veins to “pop” out.
If you don't have much fat on your hands, your veins can be more prominent. Age. As you get older, your skin gets thinner and loses elasticity, making your veins more visible. Also, as you age, your valves in your veins weaken.
One common physical change among aging populations is the increase of visible, bulging veins, specifically in the legs. “Our veins are designed with a valve which works to control proper blood flow in the extremities back to the heart,” says Paul Corcoran, M.D., a vascular surgeon for Henry Ford Health.
The stored fat around your midsection (for men) is typically the last to leave your body, even after months or years of an exercise plan. It is difficult to lose those last few pounds. For women, the last few pounds of fat is typically stored in the hips, buttocks and thigh region.
No matter how much isolation work you do, the vein will pop up only when your body fat percentage comes down to around 12 per cent. A real vascular vein is visible when you hit the single digit.
“When muscle and carbohydrates bind with water, the muscle expands, [pushing on veins] so the veins pop out more,” says Ginsburg. But if your sodium is high, you will end up looking puffy because the body tries to maintain a certain ratio of water to sodium and will hold on to extra water to keep that ratio.
Some people are genetically predisposed to having problematic veins, or their age causes the veins to be smaller or hidden. In most instances, however, it is a matter of the patient being dehydrated.
Adrenaline causes your heart to beat faster and squeezes arteries and veins, making your blood pressure increase. Your blood pressure usually goes back to normal once you are no longer angry, or the stressful event is over.
