Of their quest for sculpted biceps, most weightlifters examine hammer curls vs. biceps curls.
Particularly, they wish to know the variations, why they’re helpful, how one can carry out every, and which is greatest.
On this skilled comparability of the hammer curl vs. bicep curl, we’ll discover these factors and extra.
Hammer Curl vs. Bicep Curl: What’s the Distinction?
Hammer curls and biceps curls are isolation exercises that primarily prepare the biceps brachii, or “biceps muscle groups.” Each contain lifting a dumbbell by bending and straightening your elbow.
The distinction between hammer curls vs biceps curls is the grip: you carry out hammer curls with a impartial grip (palms dealing with in) and biceps curls with a supinated grip (palms dealing with up).
Analysis presents a number of insights into the impact of this distinction.
Older research suggests hammer curls emphasize the brachialis and brachioradialis, two small muscle groups that add measurement to your higher arms and forearms. Nevertheless, newer research partly challenges this discovering, suggesting the brachioradialis is extra energetic when performing curls with a supinated grip.
A study revealed within the Scandinavian Journal of Medication & Science in Sports activities discovered that the traditional biceps curl lengthens the biceps greater than the hammer curl, which can benefit biceps development. And one other study by the Università Degli Studi di Milano discovered common biceps curls elicited extra biceps activation than hammer curls. Sadly, methodological flaws make these outcomes tough to interpret.
Critically, analysis has but to look at variations in muscle development between these workouts. Since greater activation doesn’t at all times lead to larger development, we want extra analysis earlier than figuring out if any important variations exist between these workouts in observe.
Hammer Curl vs. Bicep Curl: What Are the Advantages?
The first advantage of the biceps and hammer curls is that they successfully prepare your arm muscle groups, particularly the biceps, serving to you maximize your arm measurement and energy. Additionally they prepare the forearm muscle groups to a excessive diploma, which seemingly advantages grip energy and ensures your arms develop proportionally.
Each allow you to coach your biceps unilaterally (one after the other), too. The benefit is that you could lift extra whole weight than you’ll be able to with bilateral workouts (workouts that prepare each side of the physique concurrently), which can help you acquire extra muscle and energy over time.
Furthermore, it could aid you set up a stronger mind-muscle connection and discover and repair muscle and strength imbalances.
One benefit particular to the hammer curl is that it emphasizes the brachialis muscle groups extra successfully than different curl variations. The brachialis is a small muscle that lies beneath the biceps, which, when effectively developed, considerably provides to your higher arms’ measurement and circumference.
Hammer Curl vs. Bicep Curl: Kind Variations
How you can Do the Hammer Curl
- Stand together with your toes shoulder-width aside, holding a dumbbell in every hand at your sides and your palms dealing with your thighs.
- With out twisting your wrist, bend your proper elbow to twist your proper hand towards your proper shoulder.
- Reverse the motion and return to the beginning place, then repeat the sample together with your left hand to finish one full rep.
How you can Do the Biceps Curl
- Stand together with your toes shoulder-width aside, holding a dumbbell in every hand at your sides and your palms dealing with ahead.
- With out twisting your wrist, bend your proper elbow to twist your proper hand towards your proper shoulder.
- Reverse the motion and return to the beginning place, then repeat the sample together with your left hand to finish one full rep.
Hammer Curls vs. Bicep Curls: Which Is Greatest?
The hammer curl and biceps curl are equally efficient biceps workouts, so neither is best or worse than the opposite.
Whereas analysis tends to counsel the common curl trains each heads of the biceps (the lengthy head and short head) greater than the hammer curl, there’s proof the hammer curl is simpler for coaching your brachialis and brachioradialis, two muscle groups important for general arm improvement.
And that’s why evaluating hammer curls vs bicep curls isn’t significantly helpful. A extra smart strategy is to incorporate each in your coaching.
A great way to do that is to incorporate the hammer curl in your program for 8-to-10 weeks of coaching, take a deload, after which change the hammer curl with the biceps curl for the next 8-to-10 weeks of coaching.
Then, you’ll be able to both proceed alternating between the workouts each few months like this or keep on with the one you like.
That is how I like to arrange my coaching, and it’s much like the strategy I advocate in my health books for women and men, Bigger Leaner Stronger and Thinner Leaner Stronger.

Biceps Curls vs. Hammer Curls: FAQs
FAQ #1: Are hammer curls higher than bicep curls?
Hammer curls aren’t essentially higher than bicep curls—they serve a special goal. Whereas hammer curls goal the brachialis barely extra, biceps curls emphasize the biceps particularly.
For most individuals, together with each workouts in your routine will yield the perfect outcomes.
FAQ #2: Do hammer curls make biceps look greater?
Hammer curls work the brachialis barely greater than common curls. Whereas this muscle isn’t almost as distinguished because the biceps brachii, it could improve the biceps’ look by making a clearer divide between the biceps and triceps and enhancing your biceps “peak.”
FAQ #3: What’s the simplest curl for concentrating on the biceps?
Analysis means that the common biceps curl is the simplest curl for concentrating on the biceps. Nevertheless, doing a wide range of curls, together with hammer curls, preacher curls, and incline curls, seemingly produces extra balanced and full development than doing only one kind of curl.
Including selection may scale back your danger of repetitive pressure accidents and assist maintain coaching participating and enjoyable, which might make it extra productive.
FAQ #4: Ought to I am going heavy on hammer curls?
Intention to carry as a lot weight as doable on the hammer curl with out compromising kind. Most individuals discover that that is barely greater than they’ll carry on the biceps curl. For many males, doing units of 6-to-8 reps works effectively, whereas girls usually desire units of 8-to-10 reps.
FAQ #5: What’s the distinction in muscle activation between hammer curl vs bicep curl?
Analysis on muscle activation variations between the hammer curl vs biceps curl has produced blended outcomes, although it typically suggests biceps curls are superior for coaching the biceps, whereas hammer curls prepare the brachialis extra.
Importantly, no analysis has examined variations in muscle development between these workouts. Since greater activation doesn’t at all times equal extra development, it’s unsure how these variations have an effect on long-term positive factors.
