Reverse curls target the brachioradialis muscle, which runs along the thumb side of your forearm, and the extensor carpi radialis, both responsible for wrist extension and forearm size. Unlike standard biceps curls where your palms face forward, reverse curls place your hands in a pronated position, palms facing down or toward your thighs.

The mechanics matter. Starting with your arms at your sides, hold dumbbells with a neutral grip. Keep your elbows locked against your ribs throughout the movement. Curl the weight upward in a controlled arc, stopping just below shoulder height. Lower slowly to the starting position. This simple adjustment shifts tension away from your biceps and onto the often-neglected forearm musculature.

Proper form prevents injury and maximizes results. Many people swing the weights or allow their elbows to drift away from their body, which transfers load to the shoulders instead of the forearms. Your core should stay engaged and your torso stationary. The movement originates only from the elbow joint.

Weight selection determines effectiveness. Choose a load that allows 8 to 12 controlled repetitions per set. Forearm muscles respond well to moderate weights with strict form. Three sets of reverse curls once or twice weekly builds strength without overtraining smaller muscle groups.

Reverse curls pair well with hammer curls and wrist exercises in a comprehensive arm routine. Hammer curls use a neutral grip similar to reverse curls but keep the forearm in a slightly different position, hitting the brachioradialis from another angle. Adding wrist curls and wrist extensions rounds out forearm development.

Progression happens gradually. Track your weights and aim to add one or two pounds every two to three weeks. Some athletes find they plateau quickly with forearm work due to the smaller muscle mass involved. This is normal.
