Keep your palms facing your torso at all times, this is the starting position.
Now, while keeping your upper arms stationary, curl the weights while contracting your biceps as you breathe out. Continue to raise the weights until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a brief moment as you squeeze your biceps.
Slowly begin to bring the dumbbells back to the starting position as your breathe in.
Repeat this movement for the recommended amount of repetitions.
Pro Tip
**Correct Grip**: When you hold the dumbbells, make sure your palms are facing each other in a neutral grip (hence the term "hammer"). This grip targets the brachialis and brachioradialis muscles, which are located on the sides of your arms. Avoid gripping the dumbbells too tightly as this can lead to unnecessary forearm fatigue. **Controlled Movement**: Curl the weights while keeping your elbows close to your torso. The movement should be slow and controlled, both when lifting and lowering the weights. Avoid the common mistake of using a swinging motion to lift the dumbbells as this can lead to injury and reduces the effectiveness of the exercise
