Cross Body Triceps Extension With Resistance Bands

Isolate and fully contract your triceps through a natural cross-body pull that bands make uniquely effective.

Primarily trains: Primarily develops the triceps brachii (all three heads) through elbow extension under constant band tension across the body's midline.

Cross Body Triceps Extension With Resistance Bands — demonstration

Step-by-step demonstration

Sets & reps

3 sets × 12–15 reps per arm, 45–60 s rest between sets; the band's accommodating resistance and this rep range together optimise triceps hypertrophy for beginners.

Tempo

2-1-2 — a 2-second controlled extension, 1-second squeeze at lockout, and 2-second return maximises time under tension for hypertrophy in this isolation movement.

Breathing

Exhale as you extend your arm (concentric push), inhale as you return your hand to the starting position (eccentric phase).

Step 1 of 2

Setup

Get into position before the first rep.

1Anchor the resistance band at the top of a door using a door anchor, ensuring it is secure before loading.
2Attach a single handle to one end of the band and grip it with your working hand.
3Stand approximately 90 cm from the door with your non-working side facing the anchor point.
4Place your working hand across your body so your fist rests near the opposite pectoral, palm facing inward — this is your start position.
5Set your feet shoulder-width apart, soft bend in the knees, free hand resting on your hip for balance.

Step 2 of 2

Execution

The actual movement, one rep.

1Brace your core and fix your upper arm so it stays perpendicular to the floor throughout the movement — only the elbow joint should move.
2Press your hand downward and diagonally across your body, extending the elbow until your arm is fully straight.
3Pause briefly at full extension and actively squeeze the triceps before returning.
4Control the band as it pulls your hand back up and across to the starting position near the opposite chest.
5Complete all reps on one side before switching arms.

Form cues

What a good coach would say in your ear.

Pin your upper arm — only the forearm moves.
Drive the back of your hand toward the floor, not just forward.
Keep your shoulder packed down, away from your ear.
Squeeze hard at the bottom before you let the band pull you back.
Stay tall — don't rotate your torso to assist the push.

Avoid these

Common mistakes.

The technique errors that quietly undo your training.

Allowing the upper arm to swing forward: this shifts load onto the shoulder and defeats triceps isolation — the elbow must stay fixed in space.
Using too much band resistance and compensating with torso rotation: reduces triceps stimulus and stresses the lumbar spine.
Stopping short of full elbow extension: the triceps' peak contraction occurs only at complete lockout, so cutting the range limits results.
Gripping too tightly and engaging the forearm excessively: keep the wrist neutral and grip firm but relaxed to keep tension in the triceps.
Standing too far from the anchor: excessive band pull at the start position makes controlling the upper arm very difficult and invites shoulder compensation.

Variations & progressions

Make it harder. Make it easier. Make it fit.

Overhead triceps extension with band (anchor low) — shifts emphasis to the long head of the triceps.
Bilateral band pushdown at a high anchor — a simpler regression before adding the cross-body angle.
Cross body triceps extension with a cable machine — provides consistent, non-accommodating resistance as a progression.
Single-arm cross-body extension with a dumbbell (lying) — a free-weight alternative for those without a band anchor point.

Safety

Verify the door anchor can bear the band's tension before each set — a loose anchor can cause the band to snap back and cause facial or eye injury. Avoid this exercise if you have an acute elbow tendinopathy or lateral epicondylitis, as resisted elbow extension under load may aggravate the condition. Individuals with shoulder impingement should confirm the fixed upper-arm position is pain-free before proceeding. Stop immediately if you feel sharp pain in the elbow joint or wrist.
