The barbell fat bar reverse curl is a forearm and grip-building exercise performed with a pronated (overhand) grip on a thick "fat" barbell. The reverse curl trains the brachioradialis and forearm extensors while the brachialis and biceps drive elbow flexion, and the oversized bar forces your hands and forearm flexors to work overtime to hold on. It is a strong accessory for thicker forearms, a more crush-resistant grip, and stronger lockouts on pulls and curls.

Barbell Fat Bar Reverse Curl: So führst du sie aus

  1. 1Load a thick (fat) barbell on the floor or a rack and stand tall with your feet about hip-width apart.
  2. 2Take a shoulder-width, pronated grip on the fat bar with your palms facing down and knuckles pointing forward.
  3. 3Stand upright with the bar resting against your thighs, arms straight, and a firm grip wrapped fully around the thick handle.
  4. 4Brace your core, tuck your elbows against your sides, and keep your wrists straight and neutral.
  5. 5Curl the bar up by flexing at the elbows, keeping your upper arms still and your knuckles driving toward your shoulders.
  6. 6Squeeze the brachioradialis and forearms at the top, holding the contraction briefly without letting your wrists roll back.
  7. 7Lower the bar under control back to your thighs until your arms are fully extended.
  8. 8Complete your reps, then set the bar down on the floor or rack with control.

Technik-Tipps

  • Keep your wrists straight rather than curling them — the work should come from the elbow, not the wrist.
  • Pin your elbows to your sides so the brachioradialis and forearms do the lifting instead of your shoulders swinging the bar up.
  • Because the thick bar taxes your grip first, expect lower weight than a standard reverse curl and stop the set when your grip fails, not your arms.
  • Use a slow, controlled tempo on the way down to maximize forearm tension and grip time under load.

Häufige Fehler

  • Swinging the torso or heaving with the lower back to start the rep, which shifts work off the forearms and risks straining your spine.
  • Letting the wrists bend or roll backward at the top, which strains the wrist and takes tension off the brachioradialis.
  • Going too heavy so the grip gives out early, ending the set before the forearms and elbow flexors are properly worked.
  • Letting the elbows drift forward or flare out, turning the reverse curl into a swing and reducing the load on the target forearms.

Häufig gestellte Fragen

What muscles does the barbell fat bar reverse curl work?

It mainly trains the forearms — the brachioradialis and wrist extensors — while the brachialis and biceps act as the elbow flexors. The thick fat bar adds heavy demand on your grip and forearm flexors to hold the bar.

Why use a fat bar instead of a standard barbell?

The oversized handle forces your hands and forearm flexors to grip harder, so you build a stronger, more crush-resistant grip and thicker forearms alongside the reverse curl. Expect to use less weight than on a standard bar.

How is a reverse curl different from a regular curl?

A reverse curl uses a pronated (overhand, palms-down) grip, which shifts the emphasis onto the brachioradialis and forearm extensors instead of the biceps peak you get with a palms-up curl.

How many sets and reps should I do?

As a forearm and grip accessory, 3–4 sets of 10–15 controlled reps works well. Pick a weight you can hold and grip for the full set rather than chasing heavy loads.

Can I do this without a fat bar?

Yes — use a standard barbell with the same overhand grip for a regular reverse curl, or add thick-grip sleeves to a normal bar to mimic the fat-bar grip challenge.
