Muscles worked

Primary

  • Pectorals

Secondary

  • Serratus anterior
  • Trapezius

Equipment

  • Barbell

Setup

  1. Secure one end of the barbell in a landmine attachment and stand perpendicular to the bar.
  2. Grip the end of the barbell sleeve with your inner hand using a neutral or slightly underhand grip.
  3. Position your feet in a staggered stance with the leg opposite the working arm forward for stability.
  4. Maintain a slight bend in the elbow and keep your chest lifted.

How to do it

  1. Exhale as you sweep the bar across your body in an upward arc toward the midline of your chest.
  2. Focus on bringing your bicep toward your sternum to maximize pectoral contraction.
  3. Inhale as you slowly lower the bar back to the starting position, maintaining tension throughout the eccentric phase.
  4. Complete all reps on one side before switching to the other.

Form checklist

  • Keep the elbow at a fixed angle; do not turn this into a press.
  • Ensure the torso remains stationary and does not rotate with the weight.
  • Keep your shoulders retracted and depressed to avoid excessive trap involvement.
  • Control the weight on the way down to prevent the bar from pulling you out of alignment.

Pro tips

  • Place your free hand on the working pectoral to physically feel the muscle fiber recruitment.
  • Imagine scooping the weight toward your opposite shoulder to better engage the inner chest fibers.
  • Lean slightly toward the landmine to increase the range of motion and stretch at the bottom.

Make it harder

  • Incorporate a 2-second isometric hold at the peak of the contraction.
  • Slow the eccentric phase to 4 seconds to increase mechanical tension.
