What Muscles Do Incline Hammer Curls Work?
Primary muscles involved in dumbbell hammer curls:
- Biceps: The biceps brachii is the large muscle that lies on the anterior part of the upper arm between the shoulder and the elbow. It arises on the scapula and runs towards the upper forearm. The biceps muscle has two heads (the short head and the long head) – therefore its name. The biceps’ main function is to flex and supinates the elbow -allowing it to rotate so the palm faces up or forward. When the biceps contract, they pull up the forearm is pulled up.
Secondary muscles engaged:
- Brachialis: The brachialis muscle sits under the biceps brachii. This long muscle flexes your elbow. It connects your upper arm bone (humerus) to the long forearm bone (ulna).
- Brachioradialis: This muscle also sits in the anterior compartment of the upper arm. The brachioradialis muscle assists the brachialis with elbow flexion and connects your humerus bone to the short lower arm bone known as the radius.
- Wrist Extensors: These muscles are located along the forearm. They connect the upper arm bone (humerus) to your hand via your wrist and are involved in extending the wrists and fingers. Some of the wrist extensor muscles are the capri ulnaris, the digiti minimi, the digitorum, the indices, the pollicis brevis, and the retinaculum of the hand.
- Wrist Flexors: These muscles are also located along the forearm and connect your elbow to your hand. The wrist flexor muscles serve to flex the wrists and fingers. Your carpi radialis and carpi ulnaris flex your wrist up towards your forearm while you digitorum profundus and superficialis flexor muscles connect your forearm bone to the bones in your fingers, allowing them to curl.
Incline Hammer Curls Benefits
After learning what muscles are involved in hammer curls, let’s look at the benefits associated with the exercise:
- Hypertrophy: Hammer curls help increase bicep size.
- Strength & Endurance: Dumbbell hammer curls allow the muscle to be under tension for a longer period than when performing barbell bicep curls. This increases muscle endurance and makes your biceps stronger.
- Isolation: The hammer curl is a single-joint movement, making it great to isolate the biceps.
- Strong Wrists and Grip: Hammer curls improve wrist stability and strengthen your grip, much needed when lifting heavy and engaging in other compound moves.
- Safety: Another positive is that your wrists and elbows are less likely to be strained as it’s a more controlled movement.
- Aesthetics: Hammer curls help develop beautiful arms, which can translate into a great upper body.
- Simplicity: The incline hammer curl is a straightforward and simple movement. All you need is just a pair of dumbbells.
- Versatility: This is a versatile exercise. You can perform the exercise one arm at a time, both arms simultaneously, or alternating arms. You can even perform hammer curls with resistance bands.
How to Do Dumbbell Hammer Curls
- Approach a bench and position it on an incline angle – around a 30-degree angle.
- Sit on the bench and grab dumbbells at arm’s length in each hand.
- Rest your back against the bench and plant your feet grounded on the floor.
- Hold the dumbbells with a neutral grip so that your palms face your body. The grip is what differentiates dumbbell bicep curls from hammer curls.
- Tight up your abdominal muscles and as you exhale, slowly flex at the elbows, and curl the weights up.
- Keep your upper arms steady and your elbows close to your body.
- Hold at the top of the movement for a second or two.
- As you inhale, lower the dumbbells to the initial position in a controlled manner.
- Repeat the movement for 8 to 12-15 repetitions and for 3 sets.
- You can work both arms simultaneously, one arm at a time, or alternating arms.
Incline Hammer Curls Mistakes
Now that we know how to perform dumbbell hammer curls, let’s see what the most common mistakes associated with the exercise are:
- Not keeping the upper arms steady: Moving the arms back and forth utilizes momentum. Do not move your elbows and upper arms throughout the movement. Try to maintain your arms steady.
- Not keeping your back against the bench: Keep your back fully supported against the bench and engage your core. This allows you to perform the exercise with a full range of motion and keep proper alignment.
- Flying through the exercise: Lifting the dumbbells fast allows you to use momentum. Aim to move the weights in a controlled way. Squeeze during every repetition and slow down the timing This allows you to isolate your biceps properly.
- Lifting extremely heavy dumbbells: When you try to lift extremely heavy dumbbells, you may bring other muscles to assist in the movement, such as the core and back. Incline hammer curls require that you take advantage of the sitting angle so you can perform the full range of motion and have proper form. You can feel this exercise even with light dumbbells.
