What Are Bicep Curls?

Bicep Curls are one of the most common exercises in the gym. And they are pretty simple too.

You simply take a weight that’s on a barbell, or use dumbbells, and lift it up towards your shoulders in almost a ‘half-circle’ like motion. Here’s a video demonstrating it:

What Muscles Do Bicep Curls Build?

Bicep Curls target a TON of muscles. But, to make things less complicated- we are simply going to menton the big and important muscles.

Bicep Curls generally build as the name implies, the Bicep muscle. You can feel this muscle by flexing your arm, and feeling the muscle that points to you that is in between your elbow and shoulder.

Additionally, bicep curls build your forearms. Forearms are the muscles right between your wrists and your elbows. These muscles do a lot of lifting, especially when it comes to picking things up, opening doors, and even driving a car!

The Bicep

Most people are doing bicep curls to target the bicep. Curls target the long head and short head of the bicep, so it does work both muscle groups. Although, most argue that bicep curls are better for short head activation of the bicep.

Regardless, bicep curls will put on size to your bicep and grow your arms accordingly.

Be sure to focus on the form, not the weight of the exercise, and make sure you feel that burn when lifting. That’s a really important part!

Your forearms have to carry that weight in your hand as that weight moves up and down.

Plus, as you’re holding the dumbbell your grip strength increases too.

While you may not think forearms are important, they actually are. Big forearms make you look really strong and help complete your physique.

While this isn’t the “best” way to grow forearms, as bicep curls do not directly target the forearms, you will still see some forearm growth with it.

Make Sure You Diet Correctly

No muscle growth will ever happen with a poor diet. Make sure you are eating enough protein and calories everyday- maybe even consider a dirty bulk!
