Think of lifting weights and the image that springs to mind is probably someone curling a dumbbell. That’s in part because it’s such an effective isolation exercise, helping you to bulk up your biceps and bringing a host of other benefits when it comes to nailing other lifts.
Benefits Of Biceps Curls
Sure, biceps look great (although it’s a good idea to pair them with similarly beefed-up triceps), but they’re also key players when it comes to most pulling exercises, so you can expect to see improvements in other lifts by adding this movement to your training schedule.
Your grip strength should also benefit from regularly performing biceps curls, too, which will help you when it comes to tricky compound exercises like the pull-up, deadlift and bent-over row where your grip might be the first thing to go.
Last but not least, after nailing some biceps curls you’ll find yourself in possession of some mean-looking upper arms.
How To Do The Biceps Curl
There are biceps curl variations aplenty, but we think the best place to start is the standing dumbbell biceps curl. Remember, you want your biceps to be doing the work – it sounds obvious, but it’s all too easy to enlist other body parts to help shift the weight if you’re not strict with your form.
Stand with your feet shoulder-width apart and a slight bend in your knees, holding a dumbbell in each hand by your thighs, palms facing away from you. Keep your elbows tight to your sides throughout, your chest and head up, and back straight. Maintaining this posture will ensure you’re using your biceps and only your biceps to curl the weights.
Bend at the elbows to initiate the lift, slowly bringing the dumbbells to your shoulders over a count of three seconds. Give your biceps a slight squeeze at the top of the move to promote muscle growth. Lower slowly under control, and squeeze your triceps slightly once you get to the bottom to ensure you’ve gone through a full range of movement.
Picking The Right Weight
A lot of people in the gym want to look like their biceps can move mountains. That’s great, unless you pick a weight that’s so heavy it results in bad form, which isn’t going to help muscle development in the long run. As the biceps curl is an isolation movement, it’s vital to pick a weight that doesn’t force you to bring other muscles into the move. For instance, if the struggle to get the weights to the top is too great, more often than not people start to swing their back to get a helping hand from momentum. Do not do this. It should be all biceps.
Select a weight that allows you to complete three sets of ten to 12 reps with good form, with the third set feeling difficult.
Biceps Curls Variations
The dumbbell biceps curl will take you far but once you’ve mastered it, adding the tweaks below to your repertoire will only enhance the benefits.
Seated dumbbell curl
If you find you’re having trouble keeping your back straight, using a bench set at a high incline will help by providing support for your back.
The benefit of using a barbell is that you can load up more weight. The downside is that it’s all too easy to load up too much weight and your form will start to suffer. If you notice that you’re starting to enlist your back or anything else to aid the movement, dial it back down to something more manageable.
According to a study in the Journal Of Life And Environmental Sciences, using an EZ-bar is the best means of activating your biceps. The wavy handle is designed to put your wrists in a more natural position. This means you can add more weight with less chance of jeopardising form than when you use a barbell.
The hammer curl is a fine addition to your arsenal of moves because it also works the brachialis, a muscle just to the side of your biceps. Training your brachialis will help your overall lifting, and will also add that finishing touch to the look of your arms.
The only difference with the biceps curl is that you keep your palms facing throughout the move. Simple but effective.
If you’ve ever wondered what the isolated version of an isolation lift looks like, it looks like the preacher curl. You’ll need a preacher bench to do this exercise, but you can use either dumbbells, a barbell or an EZ-bar.
Rest your upper arms over the preacher bench with your palms facing upwards. Slowly lift until your forearms are vertical, then lower again for a three-second count.
This variation is a real test of your grip strength. Start with your palms facing towards one another. Rotate your palms to face towards you as you curl to your shoulders, making sure your elbows remain pinned to your sides. At the top of the curl, rotate your hands so that your palms are now facing away from you – this is where it gets fun. Lower slowly, over a count of between three and five seconds. Once you get closer to your starting position, turn the palms to face one another again.
