Instructions

  1. 1With a dumbbell in one hand and the palm facing your torso, bend your knees slightly and bring your torso forward, by bending at the waist, while keeping the back straight until it is almost parallel to the floor. Make sure that you keep the head up.
  2. 2The upper arm should be close to the torso and parallel to the floor while the forearm is pointing towards the floor as the hand holds the weight. Tip: There should be a 90-degree angle between the forearm and the upper arm. This is your starting position.
  3. 3Keeping the upper arms stationary, use the triceps to lift the weights as you exhale until the forearms are parallel to the floor and the whole arm is extended. Like many other arm exercises, only the forearm moves.
  4. 4After a second contraction at the top, slowly lower the dumbbell back to the starting position as you inhale.
  5. 5Repeat the movement for the prescribed amount of repetitions.
  6. 6Switch arms and repeat the exercise.

About Standing Bent-Over One-Arm Dumbbell Triceps Extension

The standing bent-over one-arm dumbbell triceps extension is performed standing with the torso leaning forward, which sets it apart from the seated version by engaging more back and leg stabilizer muscles to hold the position. It's a classic triceps isolation exercise that demands more core bracing than the seated version, while remaining very accessible since it only requires a dumbbell. The rear deltoid comes into play slightly as a stabilizer to keep the upper arm parallel to the floor. It's a good option when a bench isn't available.
