Barbell Lying Close Grip Underhand Row On Rack

  • Intermediate
  • Compound
  • Rep-based
  • Back
  • Shoulders
  • Upper arms

This chest-supported row variation isolates the back muscles by removing lower-body stabilization, while the underhand grip significantly increases biceps recruitment and lower lat activation.

Setup

  1. Place a flat bench inside a power rack, potentially elevating it on sturdy blocks or plates to allow for full arm extension without the plates hitting the floor.
  2. Set the barbell on the rack pins at a height where you can reach it with slightly bent arms while lying face down.
  3. Lie prone on the bench with your chest firmly supported and your chin just past the end of the bench.
  4. Grasp the barbell with a shoulder-width underhand (supinated) grip, palms facing forward.

How to do it

  1. Inhale to brace your core, then exhale as you pull the barbell toward your lower ribcage by driving your elbows back.
  2. Squeeze your shoulder blades together forcefully at the top of the movement, ensuring the bar makes light contact with the underside of the bench or your torso.
  3. Hold the peak contraction for one second to maximize muscle fiber recruitment.
  4. Inhale as you slowly lower the barbell back to the starting position with a controlled 3-second eccentric phase.

Form checklist

  • Keep your chest in constant contact with the bench to prevent using momentum.
  • Drive through the elbows rather than pulling with the wrists.
  • Maintain a neutral neck position by looking at the floor slightly ahead of the bench.
  • Ensure the barbell remains level throughout the entire range of motion.

Pro tips

  • Focus on the 'mind-muscle connection' by imagining your hands are merely hooks and you are pulling from the elbows.
  • At the bottom of the movement, allow your shoulder blades to protract (spread apart) for a deep stretch of the lats and rhomboids.

Make it harder

  • Implement a 'dead-stop' at the bottom of each rep by resting the bar on the pins to eliminate all elastic energy.
  • Add a 3-5 second isometric hold at the top of each repetition to increase time under tension for the mid-back.
