What equipment do I need for the Dumbbell One-Arm Wrist Curl?

You only need a dumbbell and a bench for proper support. If you don't have a bench, you can perform the exercise seated in a sturdy chair with your forearm resting on your thigh.

How To Do

Sit on a bench with your forearm resting on your thigh, palm facing up, and your wrist hanging just past your knee while holding a dumbbell. Keeping your forearm still, curl the dumbbell upward by flexing your wrist, then slowly lower it back down. Move in a controlled manner and focus on squeezing your forearm at the top.

Step-by-Step Instructions

Sit on a bench with your legs apart and feet flat on the ground. Hold a dumbbell in one hand with an underhand grip (palm facing up). Rest your forearm on your thigh, allowing your wrist to hang just beyond your knee.
Keep your forearm stationary and slowly lower the dumbbell by extending your wrist downward. This is the starting position.
From the starting position, curl the dumbbell upward by flexing your wrist. Squeeze your forearm muscles at the top of the movement.
Slowly lower the dumbbell back to the starting position in a controlled manner.
Repeat for the desired number of repetitions, then switch to the other hand and repeat the exercise.
