Bodyweight Standing Straight Arm Chest Fly

  • Beginner
  • Isolation

  • Chest

This isolation movement targets the pectorals and anterior deltoids by mimicking the mechanics of a cable fly using only bodyweight and tension. It is highly effective for improving mind-muscle connection and shoulder mobility without the need for equipment.

Muscles worked

Primary

  • Pectorals

Secondary

  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Stand tall with your feet shoulder-width apart and a slight bend in your knees.
  2. Extend your arms out to the sides at shoulder height, forming a 'T' shape with your body.
  3. Turn your palms forward and slightly retract your shoulder blades to open the chest.
  4. Maintain a soft bend in the elbows to protect the joints throughout the movement.

How to do it

  1. Exhale and slowly bring your hands together in a wide arc in front of your chest, as if hugging a large tree.
  2. Squeeze your chest muscles forcefully as your hands meet, holding the peak contraction for one second.
  3. Inhale and slowly reverse the movement, returning your arms to the starting 'T' position until you feel a light stretch in the chest.
  4. Maintain a controlled tempo of 2 seconds to close and 2 seconds to open.

Form checklist

  • Keep your shoulders depressed (down) and away from your ears.
  • Ensure your arms stay at shoulder height; do not let them drop toward your waist.
  • Avoid arching your lower back or leaning forward as you move your arms.
  • Keep your core engaged to stabilize your torso throughout the set.

Pro tips

  • Focus on 'pushing' with your inner elbows rather than just moving your hands to better isolate the pectorals.
  • Create internal resistance by tensing your chest and arm muscles as if you are moving through thick water.

Make it harder

  • Slow the eccentric (opening) phase to 5 seconds to increase time under tension.
  • Perform the movement while standing on one leg to add a significant core stability challenge.
