The cable one arm wrist curl is a single-arm isolation exercise that targets the wrist flexors on the underside of the forearm. Using a low cable for constant tension, it trains one arm at a time to build forearm strength, grip endurance, and even side-to-side development.
Cómo hacer el Cable One Arm Wrist Curl
- 1Attach a single handle to a low cable pulley and select a light weight.
- 2Kneel or sit beside the bench and rest your working forearm along it, palm facing up, with your wrist and hand hanging just past the edge.
- 3Grip the handle with an underhand grip and let the cable pull your wrist into extension so your fingers open slightly.
- 4Keeping your forearm flat and still, curl the handle upward by flexing your wrist and squeezing toward your inner forearm.
- 5Pause briefly at the top with your wrist fully flexed.
- 6Lower the handle under control until your wrist is fully extended and you feel a stretch along the underside of your forearm.
- 7Complete all reps on one arm, then switch sides and repeat with the other forearm.
Consejos de técnica
- Move only at the wrist — keep your forearm pinned to the bench so the wrist flexors do all the work.
- Let the handle roll toward your fingertips at the bottom, then curl it back up to recruit the flexors through a full range.
- Use a slow, controlled tempo; the cable keeps tension on the muscle the whole rep, so heavy weight is unnecessary.
- Keep your shoulder and elbow relaxed and out of the movement to avoid cheating the rep.
Errores comunes
- Using too much weight, which forces your elbow and shoulder to help and takes tension off the wrist flexors.
- Cutting the range of motion short, which limits the stretch and contraction the forearm gets and slows progress.
- Lifting your forearm off the bench, which turns the wrist curl into a partial biceps movement and reduces forearm work.
- Jerking or swinging the handle up instead of curling smoothly, which risks straining the wrist and loses muscular tension.
Preguntas frecuentes
What muscles does the cable one arm wrist curl work?
It isolates the wrist flexors on the underside of the forearm. Because it is done one arm at a time, it lets you focus on each forearm individually.
Why use a cable instead of a dumbbell for wrist curls?
The cable keeps constant tension on the wrist flexors throughout the entire range, including at the top, where a dumbbell unloads. This makes it effective with lighter weight.
How many sets and reps should I do?
Forearms respond well to higher reps. Aim for 2–4 sets of 12–20 reps per arm with a controlled tempo and a light to moderate weight.
Is the cable one arm wrist curl good for beginners?
Yes. It is a simple, low-risk isolation exercise. Start with a very light weight to groove the movement and protect your wrist before adding load.
Where should I feel the cable one arm wrist curl?
You should feel it in the wrist flexors along the underside of your forearm, with a stretch at the bottom and a strong squeeze at the top of each rep.
