How each one starts
Body-Up — first steps
- Start by placing your hands on a raised surface, such as a bench or parallel bars, with your palms facing down and fingers pointing forward.
- Extend your legs out in front of you, keeping your heels on the ground and your body straight.
Cable Alternate Triceps Extension — first steps
- Stand facing the cable machine with your feet shoulder-width apart.
- Hold the cable handle with your right hand and bring your arm up so that your upper arm is parallel to the ground and your elbow is bent at a 90-degree angle.

Which should you choose?
The Body-Up needs no equipment and scales through leverage, tempo and reps. The Cable Alternate Triceps Extension 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 triceps adapting.
