Different types of bicep dents and causes
A bicep dent is a small indentation that can be found on the upper part of the bicep. It’s usually about an inch or two below the shoulder and is more noticeable when the arm is flexed.
There can be multiple causes of bicep dents, but the most common one is simply genetics. Some people are just born with a natural indentation in their bicep, and there’s nothing that can be done about it.
There are multiple variations in dents when it comes to the biceps.
This form of a bicep dent or “gap” is normal:

This dent or “gap” in the bicep is called an “elbow pit.” It’s a result of the biceps tendon attaching to the humerus (upper arm bone) at the elbow. This is perfectly normal and nothing to worry about.
The other type of bicep dent is caused by excess fat deposits in the area. This is more common in people who are overweight or obese. When the fat accumulates in the upper arm, it can cause a small indentation.
Being overweight or obese is not the only thing that can cause this type of bicep dent. Anyone can develop this problem, even if they’re at a healthy weight. It’s simply a matter of where the fat deposits accumulate.
The other common dent in the bicep is this:

This dent is cause by a bicep tear that has healed. The indentation is the result of the scar tissue that has formed during the healing process.
This type of dent is not harmful and will not cause any pain. In fact, you may not even notice it unless you flex your bicep and take a close look.
If you have a bicep dent that is causing you pain, it’s important to see a doctor. This could be a sign of a more serious condition, such as a rotator cuff tear.
Bicep dents that are not painful and do not cause any other symptoms can be left alone. However, some people may want to get rid of them for cosmetic reasons.
You can also have a popeye dent:

A Popeye dent is caused by the biceps tendon rubbing against the humerus, or upper arm bone. This can happen due to repetitive motion, such as lifting weights, or from an injury.
Popeye dents are not harmful, but they can be painful. If you have a Popeye dent, you may notice pain when you flex your biceps or when you extend your arm.
If you have a Popeye dent, you may want to see a doctor. They can prescribe medication to help relieve the pain and inflammation. Physical therapy may also be recommended.
You may also have a pseudoaneurysm:
A pseudoaneurysm, or false aneurysm, is a rare type of bicep dent. It occurs when an artery is damaged and blood starts to leak into the surrounding tissue. This can cause the area to swell and form a dent.
Pseudoaneurysms are serious and can be life-threatening. If you think you may have a pseudoaneurysm, it’s important to see a doctor right away.

Some of these bicep dents are preventable, while others are not. If you experience any pain you should seek medical attention right away to rule out any serious conditions.
How to avoid some bicep dents
There are some dents that you can avoid by taking some preventative measures. If you are overweight, losing weight can help to reduce the appearance of fat deposits in the upper arm.
You can also try to avoid injuries by using proper form when lifting weights and avoiding repetitive motions that could strain the biceps tendon.
If you have a Popeye dent, there are some exercises that can help to strengthen the muscles and tendons around the elbow. This can help to reduce the pain and inflammation.
Surgery is an option for some people who want to get rid of their bicep dents. This is usually only recommended for those who have dents that are causing pain or affecting range of motion.
Surgery is a serious decision and should not be taken lightly. Be sure to talk to your doctor about all of the risks and benefits before making a decision.
