Set up
- 1Clear a safe path for picking up and setting down the dumbbells.
- 2Use a controlled kick-up or a spotter for heavy pressing variations.
- 3Position the upper arms so the elbows can remain still and the biceps begin lengthened.
- 4Choose a handle and wrist angle that allow a full curl without bending the wrist.
How to perform it
- 1Stand up with your torso upright and a dumbbell on each hand being held at arms length. The elbows should be close to the torso.
- 2The palms of the hands should be facing your torso. This will be your starting position.
- 3Now, while holding your upper arm stationary, exhale and curl the weight forward while contracting the biceps. Continue to raise the weight until the biceps are fully contracted and the dumbbell is at shoulder level. Hold the contracted position for a brief moment as you squeeze the biceps. Tip: Focus on keeping the elbow stationary and only moving your forearm.
- 4After the brief pause, inhale and slowly begin the lower the dumbbells back down to the starting position.
- 5Repeat for the recommended amount of repetitions.
Breathing
Exhale through the effort or shortened position; inhale during the controlled return. Keep the trunk quietly braced.
