Instructions for Proper Form
Performed on an incline bench facing down, this isolation exercise emphasizes the biceps' peak contraction. Limited shoulder movement isolates biceps effectively, promoting muscle growth, especially in the bicep peak for enhanced arm aesthetics.
- Position yourself such that the middle of your chest is roughly in line with the top of the incline bench and grasp the dumbbells directly under your shoulders with palms facing forward.
- Contract your bicep to raise the weight while keeping your elbow locked in place under your shoulder.
- Tense your bicep and hold this position for a moment at the top of the movement.
- Slowly allow the weight to descend back to the starting position.
- Alternate sides and repeat.
- Maintain good body positioning by keeping your elbows under your shoulders throughout the movement.
- You should feel this exercise in your biceps.
Tips & FAQs
Should Spider Curls be done at 30 or 45 degrees?
Spider curls are typically performed on a bench set to a 45-degree angle. This angle allows for a greater range of motion and better isolation of the biceps compared to a 30-degree angle, which might not provide the same level of muscle engagement and effectiveness.

Alternatives & Variations to Spider Curls
1. Hammer Curls
99.2 mSCORESWAPPED 1,192 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. Concentration Curl
91.3 mSCORESWAPPED 979 TIMESConcentration 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.
3. Dumbbell Bicep Curl
99.6 mSCORESWAPPED 976 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.
4. Cross Body Hammer Curls
95.4 mSCORESWAPPED 931 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.
5. Incline Dumbbell Curl
95 mSCORESWAPPED 775 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.
6. Seated Dumbbell Curl
98 mSCORESWAPPED 632 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. Cable Bicep Curl
94.9 mSCORESWAPPED 496 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.
8. Barbell Curl
98.5 mSCORESWAPPED 449 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.
9. Dumbbell Wide Curls
70 mSCORESWAPPED 434 TIMESIsolation exercise targeting the biceps with arms flared outwards. This variation alters the tension on the biceps, stimulating muscle growth in unique ways, and is beneficial for those looking to widen their bicep appearance.
10. EZ-Bar Curl
98.1 mSCORESWAPPED 399 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.
