The Assisted Pull-Up and the Cable Underhand Pulldown both train the lats as their primary muscle. The Assisted Pull-Up uses a machine while the Cable Underhand Pulldown uses a cable. Here is how they compare and when to pick each.
Side-by-side comparison
| Assisted Pull-Up | Cable Underhand Pulldown | |

How each one starts
Assisted Pull-Up — first steps
- Adjust the machine to your desired weight and height settings.
- Grasp the handles with an overhand grip, slightly wider than shoulder-width apart.

Which should you choose?
The Assisted Pull-Up fixes the movement path so you can push close to failure with less skill demand. The Cable Underhand Pulldown keeps constant tension on the muscle through the whole range of motion. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the lats adapting.

Common questions
Is the Assisted Pull-Up better than the Cable Underhand Pulldown?
Neither is universally better — both train the lats as the primary mover. The Assisted Pull-Up fixes the movement path so you can push close to failure with less skill demand, while the Cable Underhand Pulldown keeps constant tension on the muscle through the whole range of motion. Choose based on your equipment and which movement you can progress consistently.
Can I do both the Assisted Pull-Up and the Cable Underhand Pulldown in the same program?
Yes, but usually not in the same session — they overlap heavily on the lats. A common setup is one as your main movement and the other on a second training day, or alternating them block by block.
Do the Assisted Pull-Up and the Cable Underhand Pulldown work the same muscles?
Yes — the primary muscle is the same (lats) and both rely on the same supporting muscles: biceps and forearms.
