Low Cable Crossover

Trains the Clavicular Head.

How to do it

Set both pulleys at the lowest setting and take a handle in each hand with your palms facing forward.
Step forward into a split stance with your arms down and slightly behind you, cables taut.
Stand tall with your chest up and a small fixed bend at the elbows.
Sweep both hands up and inward in an arc until they meet in front of your collarbones.
Squeeze briefly at the top, where the hands are highest and closest.
Let the cables draw your arms back down and out along the same path.

Finishing at chest height. The low pulley's arc is upward, and the upper chest is only loaded if the hands finish high — stopping level with the sternum ends the movement where the tension has already gone.
Bending and straightening the elbows to get the hands higher. That is a curl added to a fly; the arc comes from the shoulder.
Shrugging at the top to add height. Once the shoulders lift toward the ears, the traps are finishing the repetition.
Treating it as interchangeable with the high crossover. Both are the chest working through an arc, but the direction decides which part of it is best placed to do the work — upward favours the fibres running from the collarbone, downward those from the ribs.
