Cable Bicep Curl

Definition

The cable bicep curl is a pull-pattern isolation exercise performed on a cable machine. The constant tension provided by the cable throughout the full range of motion makes it superior to free weights for maintaining time under tension, building the bicep and forearm endurance that supports grip strength in HYROX^® pulling events.

Technique & Form

1. Starting position: Attach a straight bar or EZ-bar to a low cable pulley. Stand with feet hip-width apart, grip the bar with an underhand grip at arm's length.
2. Curl: Flex your elbows and curl the bar toward your shoulders. Keep your upper arms stationary.
3. Top position: Squeeze your biceps for 1 second at the top.
4. Lower: Return to arm's length with a controlled 2-second eccentric. The cable maintains tension throughout.
5. Breathing: Exhale on the curl, inhale on the descent. Perform 3 sets of 12-15 reps.

Muscles Worked

• Primary movers: Biceps brachii, brachialis
• Secondary: Brachioradialis, forearm flexors
• Stabilizers: Core (anti-extension), anterior deltoid

Common Mistakes

1. Swaying the torso: The cable pulls you forward - brace your core and resist.
2. Moving too quickly: The constant tension is the advantage. Use slow, controlled reps.

Benefits

The cable bicep curl provides constant tension that free weights cannot match. This produces greater time under tension per rep, making it more effective for muscular endurance development.

HYROX^® Context

Bicep endurance supports the Sled Pull (hand-over-hand rope pulling) and Farmers Carry (sustained grip). Cable curls are an accessory exercise - programme 2-3 sets of 12-15 reps after main pulling work.

Variations & Alternatives

• Barbell Curl - Free-weight alternative for heavier loading.
• Concentration Curl - Strict unilateral variation.
• Chin Up - Compound pull with significant bicep involvement.

FAQ

Cable or barbell curls for HYROX^®? Cable curls for endurance (constant tension, higher reps); barbell curls for strength (heavier loads). Both are useful accessories.

How many sets per week? 4-6 total bicep sets per week is sufficient when combined with rows and pull-ups.
