Equipment

  • Suspension trainer

Setup

  1. Adjust the suspension straps to mid-length and stand facing away from the anchor point.
  2. Grasp the handles with an overhand grip and extend your arms directly in front of your chest.
  3. Lean forward into a plank position, supporting your weight on the handles with feet shoulder-width apart.
  4. Engage your core and squeeze your glutes to create a straight line from head to heels.

How to do it

  1. Inhale and slowly raise one arm upward and forward in a 'Superman' motion while keeping the other arm locked and stable.
  2. Maintain a rigid torso, ensuring your hips do not rotate or sag toward the floor as the lever lengthens.
  3. Exhale and use your lats and core to pull the extended arm back to the starting position.
  4. Repeat the movement with the opposite arm, alternating sides with a controlled 2-second eccentric tempo.

Form checklist

  • Keep your ears, shoulders, hips, and ankles in a straight line.
  • Avoid arching the lower back as the arm reaches overhead.
  • Ensure the stationary arm remains fully extended and does not collapse.
  • Keep your neck neutral by looking at a point on the floor slightly ahead of you.

Pro tips

  • Actively 'push' the stationary handle away from you to maximize serratus anterior and core engagement.
  • Focus on the anti-rotation aspect; imagine there is a glass of water on your lower back that you cannot spill.

Make it harder

  • Walk your feet further back toward the anchor point to increase the lean angle and gravitational resistance.
  • Bring your feet together to narrow your base of support, significantly increasing the demand on the obliques.
