The bicep curl is a great isolation exercise, how to perform it correctly. The bicep curls primary focus is the bicep, secondary focus is on the muscles of the forearms and the brachialis. There are many different ways and variations of the bicep curl, a few of the best and most common ones are listed below.
- Normal – Grip the bar just wider than shoulder width, this directly works the middle of the bicep.
- Wide – This grip works the inside of the bicep.
- Narrow – This grip works the outside of the bicep and the outside arm muscle the brachialis.
Barbell – Most common equipment for performing arm curls
Dumbbells – Allows for greater control and movement than using a barbell. It allows you to rotate your wrists to change the target area of the bicep. Palms facing forward focuses on the middle of the bicep, palms facing inward will focus on the outside of the bicep and the brachialis which is the outside arm muscle between your bicep and tricep.
Curl bar – Designed just for the arm curl and the tricep extension, the different angles on the bar reduces the stress on the wrists. Rather than using a normal barbell, the curl bar allows you to focus more on working the bicep with less stress on the wrists.
Cable machine – The cable machine allows different attachments, straight bar, curl bar, single hand grips.
Preacher bench – The preacher bench is very good because it keeps your upper arms in a fixed position so it does not allow body rocking to aid with the curl movement. It also allows for complete focus and isolation on the bicep curl.
Seated – Using a bench and dumbbells allows you to perform dumbbell curls in a seated position, it keeps your back straight helping to improve your technique.
Incline bench – I have found this to be one of the most effective ways to do dumbbell arm curls, allows for a large range of motion during the curl, you can almost straighten your arms during the technique which gives extra stress on the bicep.
The 21 Technique – Not to be used all the time, but great for adding variety and shock treatment to your biceps. All together you perform 21 reps, 7 reps using full motion, 7 reps using half motion from top to middle and 7 reps half motion bottom position to middle position.
Concentration curls – Seated single arm curls, the elbow of the curling arm is tucked in just above the knee.
