Workouts with Concentration Curl
Instructions for Proper Form
Concentration Curl is an isolation exercise that targets the biceps with a high degree of focus. Seated with legs spread, you rest one arm against the same-side thigh and curl a dumbbell from a fully extended arm position to full contraction, keeping the elbow stationary. This position minimizes the involvement of other muscles, ensuring the bicep is fully engaged throughout the movement. Concentration Curls are effective for increasing bicep strength and enhancing muscle definition. They allow for precise form control and can help identify and correct imbalances between arms.
- Sit on the edge of a bench with your knees bent and feet flat on the floor outside shoulder-width apart.
- Extend your right arm between your legs and position the right elbow against the inside of the right thigh to grip the dumbbell with the palms facing outward.
- Keep the elbow pressed against your thigh as you flex the elbow to raise the dumbbell to shoulder height.
- Your palm should now be facing your right shoulder as you lower the dumbbell back to the starting position.

Alternatives & Variations to Concentration Curl
1. Hammer Curls
99.2 mSCORESWAPPED 4,869 TIMESSimilar to other curls, this isolation exercise targets the biceps. Unlike the standard Dumbbell Bicep Curl, this variation rotates your wrist into a more natural position. This rotation also help to emphasize the long head of the bicep. This is a great exercise for adding some variety to your curls as well as developing functional strength and building muscle mass.
2. Dumbbell Bicep Curl
99.6 mSCORESWAPPED 4,699 TIMESThis exercise is one of the most common isolation, biceps exercises out there. Dumbbells help prevent compensating for strength imbalances, as well as allows plenty of freedom in your range of motion. This is a staple exercise in most workouts, and is a great way to build strength and muscle mass in your biceps.
3. Cross Body Hammer Curls
95.4 mSCORESWAPPED 2,804 TIMESCross Body Hammer Curls are a variation on the more standard Hammer Curl. Like other variations this is an isolation exercise that targets the biceps. Unlike many other Hammer Curl variations, this exercises has you bring the weight across your body instead of straight up and down.
4. Cable Bicep Curl
94.9 mSCORESWAPPED 2,542 TIMESSimilar to other curls, this isolation exercise targets the biceps. The use of cables allows you to apply tension to your biceps at a different angle than with free weights. This is especially helpful for applying tension at the top of your range of motion. Because you can maintain more tension on your biceps throughout the movement, this is especially helpful for building muscle mass in your biceps.
5. Barbell Curl
98.5 mSCORESWAPPED 2,091 TIMESAs with other curls, this isolation exercise targets the biceps. The use of a barbell adds more stability to this movement, and somewhat restricts your range of motion. This added stability means you can focus more on exertion than stabilizing the movement. This is a great variation for helping you build strength in your biceps.
6. Seated Dumbbell Curl
98 mSCORESWAPPED 2,070 TIMESSimilar to other curls, this isolation exercise targets the biceps. The use of dumbbells helps prevent compensating for strength discrepancies between sides, as well as not restricting range of motion. Performing curls from a seated position also helps to prevent cheating by swaying your body to assist in raising the weight.
7. EZ-Bar Curl
98.1 mSCORESWAPPED 1,954 TIMESSimilar to other curls, this isolation exercise targets the biceps. The use of an EZ-Bar adds some stability to the movement when compared to equipment like dumbbells. This added stability means you can focus more on exertion than stability, and is a great way to develop strength. Additionally, the EZ-Bar allows for a more comfortable grip than a barbell, as well as allows your wrist to rotate slightly which can lead to better activation of the biceps.
8. Machine Bicep Curl
93.1 mSCORESWAPPED 1,850 TIMESSimilar to other curls, this isolation exercise targets the biceps. The use of a machine adds stability to the movement by forcing you to use a fixed range of motion. This added stability means you can focus more on exertion than stabilizing the movement. Since your range of motion is fixed, this is a great exercise for learning, or to push the limits of this movement.
9. Incline Dumbbell Curl
95 mSCORESWAPPED 1,667 TIMESSimilar to other curls, this isolation exercise targets the biceps. The use of dumbbells helps to prevent compensating for discrepancies in strength between sides, while also giving you more freedom in your range of motion compared to equipment like barbells. By using an incline, you can also keep more tension on your biceps at the bottom of your range of motion which can help develop strength during that portion of the movement, as well as help you build muscle mass.
10. Preacher Curl
95.9 mSCORESWAPPED 1,401 TIMESSimilar to other curls, this isolation exercise targets the biceps. By using a preacher curl bench, you ensure that your elbows are locked in place, which prevents any swinging of your arm to assist in moving the weight. The use of an EZ-bar adds some stability to the movement, allowing you to focus more on exertion that stabilizing the movement. The combination of these two variations makes this an excellent exercise for developing strength in your biceps with minimal risk of cheating.
