Description

A strength training exercise that targets the triceps muscles. The person lies on a bench holding a barbell and lowers it until it almost touches their forehead, then pushes it back up.

How to Do Barbell Lying extension

  1. 1
    Setup

    Lie supine on a flat bench with your feet flat on the floor, ensuring your head, back, and glutes are firmly supported.

  2. 2
    Setup

    Grip a barbell with an overhand, shoulder-width grip and extend your arms straight up, holding the bar directly over your chest with elbows slightly bent to avoid locking out.

  3. 3

    Keeping your upper arms stationary and elbows pointed towards the ceiling, slowly lower the barbell by bending only your elbows until it is just above your forehead.

  4. 4

    Pause briefly, then forcefully extend your elbows to push the barbell back up to the starting position, squeezing your triceps at the top.

  5. 5

    Maintain control throughout the movement, ensuring your upper arms do not move significantly from their vertical position, isolating the triceps.

Tips

  • Keep your elbows tucked in close to your body; flaring them out can put unnecessary stress on the elbow joints and reduce triceps activation.
  • Control the negative (lowering) phase of the movement by taking 2-3 seconds to lower the weight, which increases time under tension for enhanced muscle growth.
  • Don't fully lock out your elbows at the top of the movement; stopping just short of full extension maintains continuous tension on the triceps.
  • Breathe in as you lower the barbell and exhale forcefully as you extend your arms back to the starting position.

Common Mistakes

  • ×Flaring your elbows out to the sides during the movement shifts tension away from the triceps and can strain your elbows; instead, keep them tucked in and pointed forward.
  • ×Allowing your upper arms to swing forward or backward reduces triceps isolation; keep them perpendicular to the floor throughout the exercise to maximize triceps engagement.
  • ×Lowering the barbell too far back behind your head can put excessive stress on the shoulder joint; aim for the bar to descend just above your forehead.
