How to do it

Adjust the seat of the preacher bench so the top of the pad rests comfortably beneath your armpits.
Grasp the bar or dumbbells with an underhand grip about shoulder-width apart.
Firmly position the backs of your upper arms flat against the angled pad with your feet planted.

Curl the weight up to the target angle, typically around 90 degrees of elbow flexion where tension is highest.
Hold this static position rigidly for the prescribed duration while maintaining continuous tension in the biceps.
Carefully lower the weight back down to the rack or starting rest position once the interval is complete.

Breathe continuously and steadily throughout the hold without holding your breath.

Lifting the elbows off the pad to reduce leverage.: Keep the upper arms completely flush against the preacher pad throughout the hold.
Allowing the wrists to hyperextend under the load.: Maintain a neutral or slightly flexed wrist to protect the joint and sustain forearm tension.
Holding the weight too close to vertical lockup where joint compression unloads the biceps.: Hold at roughly a right angle to keep peak muscular tension on the elbow flexors.

Use a manageable load to avoid excessive strain on the distal biceps tendon, especially near full extension.
