When you’re an newbie or aggressive bodybuilder, you’re most likely involved with extra than simply the dimensions of your muscular tissues. Mass is all effectively and good, however uncooked materials is barely half the equation — you must present it properly to win massive on the bodybuilding stage.
Consider Arnold Schwarzenegger’s well-known pecs; he had a giant chest, certain, however Schwarzenegger’s chest was additionally impeccably well-shaped (it’s how he got here to be known as the Austrian Oak). The identical holds true for Tom Platz and his out-of-this-world wheels. Chris Bumstead presides over the Classic Physique division on the Mr. Olympia in no small half because of the form and tightness of his abdominals.

However what of the biceps? Bodybuilders revere the “peak” — biceps that, when flexed, appear to actually pop off the arm. Are you able to hit the weights laborious and construct a biceps peak of your personal? In brief; possibly. Right here’s what the science helps (and debunks) about focused arm development so you may stack your arms to the ceiling.
Anatomy of the Biceps
You most likely know the right way to discover your biceps. They’re the quintessential mirror muscle, in any case. Situated on the entrance of your higher arm bone, your biceps brachii is a two-headed tissue that runs out of your scapula (that’s your shoulder blade) over your elbow joint and down onto your forearm.
Each time you bang out a set of dumbbell curls, carry out a pull-up, and even lower a bench press to your chest, your biceps are laborious at work both because the prime movers or secondary stabilizers.
The Lengthy Head and the Biceps Peak
The “two-headed” a part of biceps anatomy is essential with regards to figuring out whether or not or not you may construct a peak. Each heads of the biceps originate on the shoulder blade, albeit in numerous areas. As such, every head can carry out barely completely different anatomical duties regarding shoulder place. (1)
The lengthy head of the biceps sits on the skin of the arm and provides the biceps their peak when flexed. Consequently, some coaches and athletes imagine that manipulating shoulder place to bias the lengthy head of the biceps throughout arm workouts will end in a extra pronounced peak.
That is the place issues get sticky. That concept is backed by respectable knowledge — whenever you flex your biceps, the lengthy head does present up on the “high.” (2) What’s extra, some research have proven that “joint position,” which means the precise angle of your shoulder relative to your torso, would possibly play a major function in biceps activation on the lengthy head:
“… growing the size of the Biceps Brachii promoted elevated activation of the lengthy head in relation to the brief head in producing fast supination motions.” (3)
Nevertheless, this isn’t an open-and-shut case. Preferential activation (which means, actively attempting to make one a part of a muscle contract over one other) is a contentious matter within the scientific group.
Some research display that you could goal particular heads of a muscle by altering joint place, (4)(5) whereas different knowledge signifies that doing so doesn’t assure extra engagement with the lengthy head of the tissue, and thus, an even bigger biceps peak. (6)
What the Science Says
The jury remains to be out about whether or not or not you may construct an even bigger biceps peak simply by adjusting how you perform your curls, at the least in a laboratory setting. The proof appears to assist the concept in precept, however not in worth: Tweaking your training might theoretically make some stage of distinction, however whether or not or not you’d even discover the distinction is unclear and hasn’t been credibly studied.
There’s additionally the lingering specter of genetics to contemplate. How your muscle bellies — their bodily form — look relies upon a terrific deal on insertion factors, particularly whenever you flex them.
Quick-inserting biceps will naturally peak extra than lengthy ones. You possibly can measure this for your self by taking a look at how a lot of a niche exists between your forearm and the place your biceps begins whenever you flex it. This side of how your arms look is, sadly, out of your management.
Finest Workout routines for Constructing a Biceps Peak
Primarily based on the prevailing physique of proof, to focus on the lengthy head of your biceps, you must carry out curls that place your shoulder in hyperextension. Which is to say, together with your arms behind your torso. Listed below are a few of your choices:
Incline Dumbbell Curl
The incline dumbbell curl does nearly every thing you can need out of an arm isolation train. It’s straightforward to carry out, you don’t want loads of gear, and it completely crushes your biceps.
So long as yow will discover an angle on an adjustable bench that works for you, this motion ought to torch the lengthy head of your biceps. Simply ensure you hold your higher arm pinned again the complete time.
It might appear like an incorrectly-performed barbell curl, however don’t get it twisted — the drag curl is a respectable train and in addition occurs to be one of many solely methods to focus on the lengthy head of the biceps with a barbell.
The thought right here is easy; carry out a typical standing barbell curl, however as an alternative of conserving your higher arm pressed towards your torso, you must deliberately pull your elbows again to “drag” the bar up your physique.
Bayesian Cable Curl
You’ve most likely seen this train in your gym earlier than, even if you happen to don’t know what it’s known as. The Bayesian cable curl is a severely underrated biceps-builder, and it’s a motion that absolutely exploits the potential of the cable tree.
The train is actually a single-arm cable curl. By going through away from the cable station itself and permitting your arm to float behind your physique, you absolutely lengthen the lengthy head of your biceps. Extra stretch means more mechanical tension, which ought to confer extra development.
Pattern Biceps Peak Exercise
When you’re a beginner, you most likely shouldn’t spend an excessive amount of time specializing in one particular side of 1 muscle. Generalized arm coaching will work simply fantastic in your first few years.
Past that, although, it’s completely acceptable to decide on particular actions which will allow you to address lagging body parts. A biceps exercise meant to construct up your peaks might look one thing like this:
- Standing Barbell or Dumbbell Curl: 3 x 6
- Incline Dumbbell Curl: 3 x 8-10
- Bayesian Cable Curl: 2 x 12-15
As all the time, the foundations of hypertrophy-focused coaching apply: Choose weights which can be difficult however doable with good type, go away one or two reps within the tank on a set-by-set foundation, and focus laborious on contracting the muscle in query.
In the case of physique improvement, a muscle’s form and proportion are simply as related as how massive you may make it. Whether or not or not you may meaningfully develop your biceps’ peaks is up for debate.
- Your biceps connect out of your forearm to your shoulder blade. Altering the place of your shoulder might assist develop the lengthy head of the biceps, which contributes to the height.
- Some literature exhibits that you may goal particular areas of a single muscle for development, however these outcomes are contradicted by different knowledge.
- Workout routines like drag curls and incline curls, the place your higher arm is behind your torso, might assist deliver up your biceps peaks just a little bit. Some portion of how your biceps look when flexed is fully genetic and thus can’t be modified by coaching.
There’s extra proof in favor of the chance of rising your biceps peak than towards it, however most knowledge is correlative or circumstantial. Your outcomes might range — considerably.
The Pinnacle of Positive factors
In order for you an impressive pair of arms, your greatest guess is to buckle down and prepare them laborious for, effectively, years. It’s completely regular to need your physique to look a sure means. Nevertheless, it’s additionally important that you just not lose sight of what components are inside your locus of management, and which of them aren’t worth stressing over.
You might be able to deliver up your biceps peaks if you happen to actually pound away at a choose few workouts, however the science behind this concept is way from conclusive. Nonetheless, there’s no hurt in it. At worst, you’ll beef up your arms general — a win in each means.
