Bicep curls are not a worthless exercise. They are a great way to isolate the biceps and build muscle in that area. However, they are not the only exercise that you should do if you want to have strong and well-rounded arms.

Here are some of the benefits of doing bicep curls:

• They can help you build muscle in your biceps. The biceps are the muscles in the front of your upper arm. They are responsible for flexing your elbow and bending your arm.

• They can help you improve your grip strength. Grip strength is important for a number of activities, including lifting weights, opening jars, and carrying heavy objects.

• They can help you improve your overall arm strength. Bicep curls can help you build strength in your entire arm, not just your biceps.

However, there are also some drawbacks to doing bicep curls:

• They can be hard on your joints. If you do bicep curls with too much weight or with improper form, you can put stress on your joints. This can lead to pain and injury.

• They can be boring. Bicep curls are a relatively simple exercise. If you find them boring, you may be less likely to stick with them.

If you are looking to build strong and well-rounded arms, you should do a variety of exercises, including bicep curls. Some other exercises that you could include in your routine are:

• Overhead triceps extensions: This exercise works the triceps, which are the muscles in the back of your upper arm.

• Pull-ups: This exercise works the biceps, back, and shoulders.

• Rows: This exercise works the back and biceps.

• Push-ups: This exercise works the chest, triceps, and shoulders.

It is also important to make sure that you are using proper form when you do bicep curls. This will help you avoid injury and get the most out of the exercise.

If you are new to lifting weights, it is a good idea to talk to a personal trainer or certified strength and conditioning specialist. They can help you develop a safe and effective workout routine that includes bicep curls and other exercises.
