This one involves a D-handle attached at the top of a cable column.

A Lateral Straight-Arm Pulldown
B High to Low Cable Chop
C One-Arm Triceps Extension

Training notes:

• Keep your torso fairly perpendicular to the cable column; don't rotate your torso away from the cable column more than a few degrees as you reach the bottom of the range of motion. Doing so greatly reduces the rotational tension on your torso.

• For both of the cable tri-sets, switch the pin placement to use a heavier load on the easier exercises and use a lighter load for the most difficult exercises.

Due to the cable angle (about 20-30 degrees from your torso), this single-arm shoulder press variation creates a more challenging demand on your abs and obliques with a lighter load than using a dumbbell. Why? The greater the angle of the cable to your body, the less mechanical advantage your torso muscles have to resist the force of the cable from pulling you towards its origin. – Nick Tumminello

Conventional dumbbell rear-delt flyes maximally load your arms when they're out to the sides, which is when the posterior shoulder musculature is in a shortened range. However, they neglect to strengthen the aspect of horizontal shoulder abduction when your arm is in front of, or across, your torso – when the posterior shoulder musculature is in a mid to lengthened range.
You can combine the side-lying rear-delt flye with a side-plank, which not only helps make the side plank less boring, but also serves double-duty and maximizes your training time. – Nick Tumminello
