Muscles worked

Primary

  • Pectorals

Secondary

  • Serratus anterior

Equipment

  • Resistance band

Setup

  1. Anchor a resistance band to a power rack at chest height.
  2. Stand perpendicular to the anchor point and grasp the handle with the hand furthest from the rack.
  3. Step away from the rack until there is light tension in the band with your arm extended out to the side.
  4. Adopt a staggered stance with the foot closest to the rack forward for maximum stability.

How to do it

  1. Keeping a slight bend in your elbow, exhale as you pull the band across your body toward the midline of your chest.
  2. Squeeze your pectoral muscle at the peak of the movement, bringing your hand slightly past the center of your chest.
  3. Inhale as you slowly reverse the movement, controlling the band's resistance back to the starting position.
  4. Maintain a controlled 2-1-2 tempo (2 seconds to pull, 1 second squeeze, 2 seconds to return).

Form checklist

  • Keep your shoulder blades retracted and depressed throughout the entire set.
  • Maintain a consistent, slight bend in the elbow to avoid bicep strain.
  • Keep your torso stationary; do not rotate your hips or shoulders to help move the band.
  • Ensure your wrist remains neutral and firm, not bending under the band's tension.

Pro tips

  • Focus on bringing your inner bicep toward your sternum rather than just moving your hand to maximize chest fiber recruitment.
  • Pause for a full second at the peak contraction to overcome the band's tendency to pull you back quickly.

Make it harder

  • Step further away from the anchor point to increase the baseline resistance of the band.
  • Perform the movement with a 3-second eccentric (lowering) phase to increase time under tension.
