Diagonal pull one-arm with a cable machine seated on a stability ball

Start the pull by driving the elbows in the direction required by the exercise and let the shoulder blades move naturally. Return slowly without suddenly releasing the tension. Keep the same range from repetition to repetition instead of speeding up as you fatigue. Breathe continuously and end the set before technique starts to break down.

Choose a resistance that lets you preserve technique from start to finish. You should feel most of the work in abdominals, shoulders, lower back and middle and lower trapezius; if you feel sharp pain, joint pinching or a clear loss of control, reduce the load or range and stop if symptoms persist. For unilateral variations, complete the same number of repetitions and a comparable range on both sides.
