Which should you choose?
The Bench Dip (Knees Bent) needs only a sturdy bar, rings or a station and scales through leverage, tempo and reps. The Exercise Ball Dip adds an unstable surface that raises core demand. 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.
