How to Do a Concentration Curl for an Arm Workout

Learn how to do a concentration curl from personal trainer Brett Azar in this Howcast home arm workout for men video.


Okay. So today we're going to go over a dumbbell concentration throw. This is a very old school exercise. You see most guys doing this in their workouts during their arm workouts. It's a very simple exercise but it's very easy to get wrong.

Now, with this again, your focus here is to work that bicep through its full range of motion. Really get some blood into it. Good concentrated curls. Now, you're going to choose a weight that you're very comfortable with that you don't have to cheat the exercise with so you don't have to rock your body or anything. You can stay real firm and real concentrated. That's why it's called a concentration curl.

With this exercise, you're going to keep your wrists up to the sky, palms to the sky, supinated the whole time. Now, as you come up, you see a lot of guys who don't know what to do with their wrist. As a rule, when you come up, if you try to squeeze so that your pinkies rotate up, it'll actually peak out the bicep a little more. So guys always talk about they want that peak in their bicep. Well what you do is you rotate so that your pinky goes up and thumb goes down. That really contracts that muscle to its fullest. So during concentration throw, that's exactly what you want to try to do. Notice I'm rotating the dumbbell so the pinky comes up.

Now, it's also important to breathe during this exercise. Any time you work against gravity is when you want to breathe out. So I'm bringing it up, working against gravity, breathe out. Really squeeze that muscle. Concentrate that muscle. Release, come down slow. Never ever do you want to jerk up and drop it. It's not going to do anything for that muscle. It's not going to do anything for your results. The best results are when you're concentrated.

Up, squeeze, down, release. Squeeze, down, release. Now, if size is your goal, then you want to shoot for ten to 15 reps, maybe eight. But 12 is really the standard. So after you perform 12 with one arm, obviously you want to switch to the other. You're going to support your elbow with your leg here. You never want to lock out your elbow completely because that'll do damage to that joint. So you're always going to keep a slight bend in your elbow. Same thing as the other arm. Come up, squeeze, try to rotate your pinky a little tiny bit up. Really peak out your bicep. Come back down. Controlled. Breathe out, squeeze, inhale. And that's your concentration throw.
