So, What Exactly is the One Arm Lying Dumbbell Extension?

Ah, good question! The One Arm Lying Dumbbell Extension, sometimes referred to as the “Lying Single Arm Dumbbell Extension”, is an isolating exercise focusing on the triceps—the muscles located on the backside of your upper arm. And hey, who doesn’t want those toned, sculpted arms?

Steps to Master the One Arm Lying Dumbbell Extension

  1. Start Right: Begin by lying down on a flat bench with your head hanging slightly off the edge. Plant your feet firmly on the ground. Got a dumbbell nearby? Awesome, grab it with one hand.
  2. Positioning: Hold the dumbbell straight up over your shoulder. Your palm should be facing inwards, towards your feet.
  3. The Descent: Slowly bend your elbow, letting the dumbbell descend toward the side of your head. The magic here is in the elbow: make sure it remains stationary and only the forearm moves.
  4. Feel the Stretch: Bring the dumbbell down until you feel a slight stretch in your triceps. No need to rush; slow and steady wins this race!
  5. The Ascent: Now, use your triceps to extend the dumbbell back to the starting position. Squeeze those triceps at the top!
  6. Switch It Up: Once you’ve completed your reps for one arm, switch to the other. Balance is key in every workout.

Remember, if you’re new to the exercise world, it’s always smart to start with a lighter weight and focus on getting the technique down.
