Which should you choose?
The Cable Alternate Triceps Extension keeps constant tension on the muscle through the whole range of motion. The Triceps Dip needs only a sturdy bar, rings or a station and scales through leverage, tempo and reps. 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.
