Arching the lower back
Brace your abs and ribs down, or sit with back support, to keep the spine neutral.
Isolation · Dumbbells
A triceps extension with a dumbbell held overhead, lowered behind the head and pressed back up. It trains the triceps in a deep stretch, especially the long head. Good for anyone wanting fuller upper arms who has decent shoulder mobility.
The long head of the triceps crosses the shoulder, so raising the arm overhead stretches it and makes it work harder. The lateral and medial heads still help straighten the elbow.
Brace your abs and ribs down, or sit with back support, to keep the spine neutral.
Keep the elbows narrow and pointing forward so the triceps stay loaded.
Lower until the forearms are close to the biceps, within a range your shoulders tolerate.
Surpass starts the overhead tricep extension at 10–15 reps with about 1 reps in reserve. As an isolation exercise it fits well after your main compound lifts.
Add reps first, then move up in small dumbbell jumps. If heavy dumbbells become awkward to get overhead, switch to a cable or EZ-bar overhead extension.
Surpass shows what you lifted last time beside a target for this set, and adjusts it from your reps and RIR. Free on iPhone, no account needed.
These train the same main muscles. Swap when the equipment is busy, something hurts, or progress has stalled for several weeks.
Yes. Putting the arm overhead stretches the long head, which makes this one of the best ways to train it. Pair it with a pushdown for well-rounded triceps work.
Seated with back support makes it easier to keep the lower back neutral and focus on the triceps. Standing is fine if you can stay braced without arching.
