How to do it

Starting position

  1. Set the cable pulley to chest height.
  2. Grab the opposite handles with both hands and cross them in front of your body.
  3. Set your feet shoulder-width apart and lower your center of gravity.
  4. Lean your torso slightly forward to get ready.

Movement

  1. Pull your arms outward in a wide arc.
  2. Focus on the tension in your rear delts and open your arms all the way.
  3. Slowly return to the starting position.

Breathing

Exhale as you pull the handles, and inhale as you return.

Trainer tips

  • Cross the cables in an X and grip them
  • Keep your elbows straight and spread your arms out and back
  • Bring them together slowly while feeling the tension

Cautions

  • If you use momentum, it strains your shoulder joints, so keep your body stationary.
  • If your wrists bend, it can cause joint pain, so keep them straight.
  • Arching the body back while pulling
  • Bending the elbows and turning it into a row

How GYMKC sets the weight for this exercise

For example, if you do 12 reps with 40 kg and log that you could have done about 2 more, GYMKC estimates your 1RM at about 62.6 kg.

With the cable machine, each step is 5 kg (10 lb), so the next weight is 45 kg. Within your 12–15 reps target, the sets you log decide whether to add reps first or add weight.

These numbers are an example of how the calculation works. Your actual prescription is recalculated every set from your own records. See how the calculation works
