Cable Curl: Muscle Map, Form Cues, Swaps & Workout Builder

How to do the Cable Curl

Set up. Attach a straight bar or EZ handle to a low cable. Stand facing it holding the bar with an underhand grip, arms straight.

Curl the bar up, elbows at your sides.
Squeeze at the top.
Lower under control.

Form cues

Stand tall.
Keep the elbows still.
Keep tension at the bottom.

Common mistakes

Leaning back.
Letting the elbows rise.

Muscles worked

Main target: Biceps. The biceps runs down the front of the upper arm. It bends the elbow and turns the palm up, and it helps in every pull.

On the way: Forearms.

Its other side: Triceps, in the arms pattern.

What to pair it with

Movements that round out a workout with the Cable Curl, from the same catalog the StatBlockFit app logs.

Triceps Pushdown Superset partner: it trains the other side of the arms pattern, so the two can alternate.
Seated Cable Row Same pull session: it trains the upper back.
Lat Pulldown Same pull session: it trains the lats.

A complete workout around it

Alternatives and swaps

The same main muscle with other equipment: a swap never changes the muscle a workout trains.

Home or dumbbell swap
Dumbbell Curl
Dumbbell
Gym or cable swap
Preacher Curl
Machine

A swap describes the movement, not your body: if a joint hurts, ask a professional before you train it.

Working weight and 1RM calculator

Enter a set you did: the weight, the reps and how many more reps you had left in you. The estimate is the formula the StatBlockFit app uses for its records, weight × (1 + (reps + reps in reserve) ÷ 30); above 12 reps it is rough.

Training zones

Training zones
Zone	Share of 1RM	Usual reps
Strength	85 to 90 %	3 to 6
Muscle growth	70 to 80 %	6 to 12
Endurance	60 to 65 %	15 to 20

A warm-up before the working sets: 50 % for 5, 70 % for 3 and 85 % for 1, each rounded down to a plate.

Common starting points, not a prescription: the right weight is the one you can lift with good form for the reps you planned.

Variations and preparation

A variation of: Barbell Curl.

Other variations of the Barbell Curl: EZ-Bar Curl, Dumbbell Curl, Preacher Curl and Reverse Curl.

Its variations: Behind-the-Body Cable Curl.

Do before it: Wrist Mobilisation (same movement, lighter).

Track it in StatBlockFit

In the StatBlockFit app the Cable Curl is logged set by set: the app suggests your next weight after each session, times your rests, keeps your records and shows the 72-hour recovery of every muscle on its training map. The training guide explains how.
