The very best workouts for constructing your forearms are ones that depend on grip power to carry or pull a heavy weight—deadlifts, Romanian deadlifts, pull-ups, shrugs, and all heavy rows.
And more often than not, these traditional power coaching workouts are all you’ll want to construct a pair of proportionate, robust, muscular forearms.
9 instances out of ten, when somebody claims their forearms are “undersized,” the wrongdoer is an absence of heavy pulling, not an absence of devoted forearm workouts.
That stated, should you really feel your forearms are lagging regardless of your heavy pulling, there are two issues you are able to do about it:
- Use weightlifting straps sparingly.
Weightlifting straps make it simpler to carry heavy weights, particularly on deadlifts, rows, and lat pulldowns.
This prevents your grip power from turning into a limiting consider your units, but it surely additionally reduces how onerous your forearms must work.
I like to recommend you utilize straps sparingly to get one of the best of each worlds.
Particularly, I like to recommend utilizing straps solely in your heaviest pulling workouts like deadlifts or heavy dumbbell rows (particularly if doing greater reps), and customarily making an attempt to do your first 1–2 units with out straps whereas your forearms are nonetheless recent.
- Do devoted forearm coaching.
If you happen to’ve discovered heavy pulling inadequate for growing your forearms, the following step is to incorporate some devoted forearm exercises in your weekly routine.
That stated, you solely must do a couple of units of some workouts per week. You completely don’t must overhaul your present exercises to concentrate on forearms (by doing workouts like towel pull-ups, as an illustration). You additionally don’t want to begin squeezing a grip coach at your desk all day till your forearms are so sore and cramped you possibly can’t sort.
All you want is a handful of dumbbell workouts that prepare your forearms’ principal features via a full vary of movement and make it simple to incrementally add resistance over time.
The Finest Forearm Exercises with Dumbbells
Under is one of the best dumbbell exercise routine for gaining forearm dimension quick.
Do every exercise—A and B—as soon as every week. Add them to the tip of two of your present coaching classes on nonconsecutive days that don’t already embrace a lot grip work (no deadlifts, rows, pull-ups, and many others.).
For instance, say you observe the PPL cut up coaching push on Monday, pull on Wednesday, and legs on Friday. Add Forearm Exercise A to the tip of Monday’s push exercise and Forearm Exercise B to the tip of Friday’s legs exercise.

Notes on the Exercises
You is likely to be questioning whether or not two units of two workouts is sufficient to make actual forearm positive aspects. The easy reply is sure.
Bear in mind, you’re already getting loads of forearm work out of your heavy pulling. These exercises solely want to coach the features of the forearms not lined elsewhere:
- Wrist flexion (transferring your palm towards your wrist)
- Wrist extension (transferring your knuckles towards your wrist)
- Elbow flexion (bringing your hand to your shoulder)
A few units of well-chosen workouts is sufficient to cowl all three.
Two extra factors to get essentially the most out of those exercises:
- Depth: End every set 1–2 reps shy of failure—the purpose the place you couldn’t do one other rep with good type. To gauge whether or not you’re reaching this level, ask your self on the finish of every set: “What number of extra reps may I’ve completed?” If the reply is greater than two, add weight or reps within the subsequent set.
- Development: Use double development. In case your exercise requires 10–15 reps of the wrist curl and also you full 15 reps in a set, improve the burden by 5 kilos in your subsequent set. If the brand new weight is so difficult which you could’t full at the very least 10 reps in subsequent units, cut back the load by 2.5 kilos.
The 5 Finest Dumbbell Forearm Workouts

To grasp why I selected these workouts, it’s price grokking forearm anatomy.
The diagrams above present the muscle groups on the within (left) and outdoors (proper) of your forearm. Wrist flexion workouts (curling your palm towards your elbow) prepare the within; wrist extension workouts (pulling the again of your hand towards your elbow) prepare the skin.
The one muscle price singling out is the brachioradialis—the muscle close to your elbow that runs in keeping with your thumb. It contributes a significant quantity to total forearm dimension, however in contrast to the opposite forearm muscle groups, it isn’t educated nicely by wrist curl variations.
It’s finest educated by biceps curls, which is why the biceps curl, reverse curl, and hammer curl are all on this record.
1. Wrist Curl
Why: The wrist curl trains your wrist flexors via a full vary of movement and permits you to progressively improve the load in small increments over time. These attributes make it the only finest dumbbell train for the muscle groups on the within of your forearm—and one of many largest drivers of total forearm mass.
Methods to:
- Sit on a bench with a dumbbell in your proper hand.
- Relaxation your proper forearm in your proper thigh along with your palm dealing with upward, then transfer your arm ahead till your wrist hangs simply previous your knee.
- Curl the dumbbell up by flexing your wrist as excessive as it’s going to go.
- Reverse the motion and return to the beginning place.
Professional Tip: On the backside of every rep, let the dumbbell roll into your fingertips earlier than curling it again up. This will increase the vary of movement and trains your forearm flexors whereas extra deeply stretched, which can assist them develop.
2. Reverse Wrist Curl
Why: The reverse wrist curl has all the identical advantages because the wrist curl. The one distinction is that it trains the muscle groups on the other facet of your forearm: the wrist extensors. These muscle groups are smaller and weaker than the wrist flexors, however they’re additionally extra seen when your arms hold at your sides. And that’s why growing the wrist extensors is important if you’d like aesthetic forearms.
Methods to:
- Sit on a bench with a dumbbell in your proper hand.
- Relaxation your proper forearm in your proper thigh along with your palm dealing with downward, then transfer your arm ahead till your wrist hangs simply previous your knee.
- Elevate the dumbbell up by extending your wrist as excessive as it’s going to go.
- Reverse the motion and return to the beginning place.
Professional Tip: Carry out the reverse wrist curl with a thumbless grip (your thumb on the identical facet as your fingers, not wrapped across the deal with). For most individuals, this feels extra secure and comfy.
3. Reverse Curl
Why: The reverse curl emphasizes the wrist extensors and brachioradialis. It really works due to how the biceps operate throughout a curl. In a daily curl, your palms face up—a powerful place for the biceps, so that they deal with many of the load. In a reverse curl, your palms face down, which weakens the biceps and shifts extra of the work to the brachioradialis. The wrist and finger extensors additionally work isometrically all through to stop the burden from bending your wrist.
Methods to:
- Stand holding a dumbbell in every hand along with your arms at your sides and your palms dealing with backward.
- Curl each dumbbells up towards your shoulders.
- Reverse the motion and return to the beginning place.
Professional Tip: Don’t attempt to preserve the dumbbells completely horizontal on the backside of the rep. It’s extra snug for most individuals to allow them to angle in barely towards one another. Forcing them flat doesn’t make the train higher—it simply places your wrists in an ungainly place.
4. Biceps Curl
Why: The biceps curl is principally a biceps train, however analysis reveals it additionally recruits the brachioradialis greater than every other curl variation. It additionally trains your wrist flexors isometrically—they must work all through the rep to maintain the burden from folding your wrist backward. That’s sufficient forearm work to earn the biceps curl a spot in a dumbbell forearm routine.
Methods to:
- Stand holding a dumbbell in every hand along with your arms at your sides and your palms dealing with ahead.
- Curl your proper hand as much as your proper shoulder.
- Reverse the motion and return to the beginning place, then repeat in your left facet.
Professional Tip: Squeeze the dumbbells onerous all through every rep. The more durable you grip, the extra your wrist flexors and brachioradialis must work, which is what turns the biceps curl right into a significant forearm train.

5. Hammer Curl
Why: The hammer curl is principally a biceps train, but it surely additionally successfully trains the brachioradialis. And it allows you to deal with heavier weights than most devoted forearm workouts, which is mostly good for gaining muscle and power.
Methods to:
- Stand holding a dumbbell in every hand along with your arms at your sides and your palms dealing with your thighs.
- Curl your proper hand as much as your proper shoulder.
- Reverse the motion and return to the beginning place, then repeat in your left facet.
Professional Tip: Hammer curls really feel simpler than different biceps curl variations as a result of the impartial grip places you in a mechanically advantageous place that permits you to raise heavier weights. Don’t take this as an invite to load up the dumbbells past what you possibly can deal with. If you happen to can’t curl the burden up with out swinging your physique or curling it throughout your physique, it’s too heavy. Drop the burden to one thing you possibly can curl with correct type.
