Katana Extension

Katana Extension is an intermediate isolation push using cable. It loads Triceps.

Why this lift

The Katana Extension is a intermediate isolation push lift. It primarily loads Triceps. Shoulders help. You need cable. Most programs place it after your main compounds, as accessory work. You may also hear it called Katana Extensions.

The triceps finish every press. Isolation work here is for the lockout you keep missing, not for a pump that replaces bench. Once the pattern feels automatic, most programs keep this as a weekly staple.

Muscles worked

• Primary: Triceps
• Secondary: Shoulders

Setup

• Set cable so the target joint can move and nothing else has to.

How to do it

1. Take Triceps through a full range. Pause where it is hardest.
2. Return under control.

Coaching cues

• Own the stretch and the squeeze.

Common mistakes

• Turning it into a compound swing. Cut the load; slow the eccentric.

How to program it

Treat the Katana Extension as accessory work: 2–4 sets after your main compounds, enough to feel the target muscle without stealing recovery from the big lifts.

If the Katana Extension does not agree with you, Bar Pushdown trains Triceps with a different setup.
