This exercise uses a Dome (or Bosu) as a seat forcing you to engage and contract your abs throughout the exercise. The name comes from having our body in the shape of a V.
Steps
Grasp a dumbbell in each hand and sit on a dome.
Keep your legs together and your knees bent.
Draw in and hold your abs and keep your back straight.
With you arms extended to your sides, curl and contract your biceps, bringing your forearms towards your shoulders.
Slowly return to the starting position.
Tips
Try to keep your balance steady and not move your legs throughout this exercise.
