Exercises / Overhead Tricep Extension
Overhead Tricep Extension
The overhead tricep extension is a dumbbell isolation movement that trains triceps first. Default rest between sets in the app: 60 s (1 min).
Also called: overhead dumbbell extension.
Rep and RIR targets by goal
These are the sets the Zyra Workouts program generator writes for a isolation exercise under each goal. RIR is reps in reserve — how many more reps you could have done when the set ended. A default the app starts from, not a prescription.
| Goal | Reps per set | RIR | Rep ceiling |
|---|---|---|---|
| Strength | 6–8 | 2 | 9 |
| Hypertrophy | 10–15 | 1 | 14 |
| General | 8–12 | 2 | 12 |
How progression steps on Overhead Tricep Extension
The app moves the load on Overhead Tricep Extension in steps of 2 kg — the fixed step the app uses for dumbbells, machines and cable stacks. The rule is the same for every exercise: the rep ceiling is the midpoint of the rep range plus the RIR target (for the hypertrophy row here, 10–15 reps @ RIR 1 → ceiling 14). Clear the ceiling and the next set is one step heavier at the bottom of the range; fall under the range floor and it backs off one step; anything between holds.
Worked example, in the app's words: Last time 25 kg × 15 · target 10–15 @RIR 1 (ceiling 14) → +3 kg → 28 kg × 10.

Frequently asked
What muscles does the overhead tricep extension work?
In the Zyra Workouts catalog the overhead tricep extension is tagged with triceps as its primary muscle and no secondary muscles. The app counts a primary set as one set for that muscle and a secondary set as half a set. Which muscles a lift loads most also depends on technique and range of motion.
How many reps and sets for the overhead tricep extension?
The app's program generator sets 6–8 reps @ RIR 2 for strength, 10–15 reps @ RIR 1 for hypertrophy, 8–12 reps @ RIR 2 for general — the isolation rule, 2–4 sets depending on goal and experience. These are the generator's defaults, not a prescription; a coach can adjust them to you.
What can I do instead of the overhead tricep extension?
The app's swap ranking (same primary muscle, then feasible in your gym, same type, same equipment) offers Skull Crusher, Tricep Pushdown, Close-Grip Bench Press and Tricep Dip (Upright). All train triceps first.
