1 - Anchor a resistance band low and slightly to the working-side of your body, then stand tall with your feet hip-width apart.
2 - Hold the band in the working hand with your arm down and slightly out to the side, palm facing backward or inward, keeping light tension on the band.
3 - Brace your core and keep your ribs down, shoulders relaxed, and neck neutral.
4 - Pull the band diagonally up and across your body, rotating the arm so your palm turns toward you as your hand finishes near the opposite shoulder or upper chest.
5 - Pause briefly at the top while keeping the shoulder blade controlled and avoiding shrugging.
6 - Slowly return along the same diagonal path to the starting position under control.
7 - Repeat for the desired number of repetitions, then switch sides.
