The best way to Do the Hex Press for Chest Dimension with out Shoulder Ache


Half dumbbell bench press and half isometric dumbbell flye, the hex press is a singular high-tension chest-builder. The hex press is carried out on a flat bench with the dumbbells squeezed collectively all through the urgent movement. This function explains why one alternate identify for this distinctive chest train is the “squeeze press.”

Hex Press

Hex Press Video Information

See the hex press in motion, demonstrated by creator Dr. Merrick Lincoln. Word the important thing strategies, then take a look at the Step-by-Step breakdown with extra kind ideas. 

The best way to Do the Hex Press Step By Step

It might appear like a close-grip dumbbell bench press however, whereas there are some similarities, there are essential variations that make the hex press stand out. Observe these steps for correct, environment friendly, and efficient method.

Step 1 — Set Up 5 Factors of Contact

Just like the bench press, the hex press is carried out on a flat bench. Maintain a dumbbell in every hand, arrange with 5 factors of contact for stability — the again of your head on the bench, your shoulder blades on the bench, your buttock on the bench, your proper foot touching the ground, and your left foot touching the ground. (1)

Kind Tip: Recruit a “spotter,” or particular person who can help you should you run into bother through the train. Any train involving weights passing over the physique requires a spotter. (1) A spotter is very necessary when studying an unfamiliar train. The spotter stands behind the bench and, if help is important, they’ll help by greedy your wrists to information the dumbbells. (1)

Step 2 — Set Your Shoulders and Squeeze the Dumbbells Collectively

Raise your chest towards the ceiling by arching your again and pulling your shoulder blades collectively. Preserve this place all through the train. With a impartial grip (palms dealing with one another), deliver the dumbbells collectively simply above your sternum and squeeze them collectively laborious.

Kind Tip: In case you’re utilizing hexagonal-shaped dumbbells — the namesake tools for the hex press — guarantee flat surfaces of the dumbbells are aligned and squeezed collectively. 

Step 3 — Preserve Stress, Press to Lockout

Provoke the press by flexing your shoulders and lengthening your elbows. Maintain the dumbbells squeezed collectively and elbows tucked all through the motion. Don’t lower inward strain as you attain the highest, locked out, place.

Kind Tip: Maintain stress. Along with the profound contraction you’ll really feel in your chest, you must really feel stress in your higher again and lats, which hold your shoulder blades pulled collectively (retracted) and hold your elbows tucked towards your sides. 

Step 4 — Decrease with out Separating

Decrease to the middle of your chest utilizing the identical arm path because the upward motion section. Give attention to maintaining the dumbbells firmly squeezed collectively all through the reducing section, which can really feel barely unnatural at first, because the reducing section of most workout routines emphasizes a muscle stretch.

Kind Tip: Take into consideration “rowing” or actively pulling the dumbbells again your chest. “Rowing” the weights again to the beginning place reinforces stress in your higher again and eliminates the necessity to reset your arch earlier than the following repletion.

Hex Press Errors to Keep away from

Dodge these frequent errors for cleaner method and simpler hex presses.

Dropping The “Squeeze” Between Dumbbells

The strain exerted between the dumbbells is a part of the particular sauce that makes the hex press efficient — and further spicy. It promotes muscular engagement in elements of the chest which may not in any other case be as energetic.

On the backside place of the train, the lifter’s elbows are bent, and shoulder inner rotation power is required to maintain the dumbbells collectively. Towards the highest place, arms are straighter, and shoulder horizontal adduction power is required to maintain the dumbbells collectively. Though it could get more durable to maintain the squeeze on the prime and backside of the motion, agency strain between the dumbbells have to be maintained all through.

Dropping Your Chest, Releasing Your Shoulder Blades, or Flaring Your Elbows

Lack of stress within the again permits the chest to drop, shoulder blades to unfold, and higher arms to float away from the lifter’s sides. These three errors are inclined to happen collectively, they usually could make the hex press much less efficient.

In case you really feel any of those faults, reset by arching your backbone, retracting your shoulder blades (and pinning them to the bench), and tucking your elbows towards your ribcage. Now, hold this stress and end.

Non-Perpendicular Stress Between Dumbbells

When squeezing the dumbbells collectively, it’s important to take care of opposing forces from the left and proper arm which might be horizontally aligned and almost equal in magnitude. In any other case, dumbbells might slip or roll aside, resulting in lack of stress, missed reps, or worse.

Get the texture of making the squeeze utilizing mild dumbbells throughout your “work up” units and deal with sustaining even, regular strain all through the exercise. 

The best way to Progress the Hex Press

When first performing the hex press, begin with comparatively mild dumbbells to hone method. When you’re snug with the train, a “working weight” 20 to 30% decrease than what you’d sometimes use for a conventional dumbbell bench press will seemingly be applicable. From there, lifters have a number of nice choices for progressing the hex press.

Squeeze More durable

The best approach to progress the hex press is to use extra inward strain to the dumbbells. Growing the “squeeze” makes the train tougher and boosts the coaching stimulus skilled by the chest and shoulder muscle mass.

Enhance Weight

Squeezing more durable through the hex press could make nearly any weight tougher, however this development technique isn’t prone to stimulate triceps progress or carry over to heavy urgent as effectively as growing the burden.

When you’re capable of hit or surpass your repetition goal on the ultimate working set, it could be time to make use of heavier dumbbells. Ideally, leaping as much as the following pair of dumbbells on the rack will drop you again towards the underside of your goal repetition vary.

Enhance Repetition Quantity

As you get stronger with the hex press, contemplate performing extra repetitions per set. For instance, should you usually carry out eight to 12 repetitions, and also you’re persistently hitting 12 reps with extra left within the tank, change your goal to 12 to 16 repetition units. Shifting the repetition vary upward helps to make sure difficult units and ongoing muscle achieve.

Advantages of the Hex Press

The hex press biases your chest whereas requiring solely mild to reasonable weights and minimal shoulder extension. Altogether, the hex press might present new chest progress and a extra shoulder-friendly urgent expertise.

Sturdy Chest Coaching

Carried out correctly, the hex press allows maximal or near-maximal chest contraction all through each repetition — a feat not doable throughout conventional presses. Right here’s why: 

Conventional workout routines are restricted by the quantity of resistance our muscle mass can overcome through the sticking level, or probably the most difficult portion of the motion. For presses, the sticking level happens towards the start of the upward motion section. (2) Throughout the the rest of the motion, your muscle mass are usually not maximally challenged. Throughout the hex press, you may guarantee your muscle mass are adequately stimulated by squeezing the weights collectively as laborious as you want

Not feeling adequately challenged? Merely squeeze the dumbbells collectively more durable to demand extra power from the chest. Furthermore, squeezing as you press nearly ensures thorough engagement of pectoralis main — Learn extra within the “Muscular tissues Labored” part under.

Reinforces Thoughts-Muscle Connection and Urgent Approach

Horizontal urgent workout routines, such because the bench press and dumbbell bench press, are a mainstay for power coaching and physique improvement. A number of technical components are frequent throughout all bench-supported horizontal urgent workout routines, together with the necessity for shoulder blade retraction and co-contraction of muscle mass across the shoulder joints. Additionally fascinating is the feeling of muscular effort from the chest. Lifters spend months, even years, honing their kind to enhance effectivity and effectiveness.

Thankfully, the hex press may help lifters to construct power, method, and a mind-muscle connection that may reinforce correct efficiency of different horizontal presses. Throughout the hex press, squeezing the dumbbells collectively creates the sensation of peak pectoralis main contraction all through the urgent motion. This sensation of “flexing the pecs” may help to reinforce the mind-muscle connection, which can be conducive to higher features. (3)

Squeezing the dumbbells collectively additionally encourages higher involvement of your rhomboids and center trapezius, as they have to counteract forces from pectoralis main, subscapularis, serratus anterior, and different muscle mass on the entrance of the torso. Rhomboids and center traps are the muscle mass primarily answerable for sustaining retraction of the shoulder blades. Elevated demand through the hex press might encourage lifters to create a tighter setup for bench-supported horizontal urgent.

Shoulder-Pleasant Urgent

People with sure shoulder issues, resembling shoulder instability, might not tolerate conventional urgent. (4)(5) People who current with apprehension and ache within the entrance of the shoulder when the arm is introduced out and prolonged behind the physique might have a particular kind of instability referred to as anterior instability. (4)(6) This downside is frequent amongst lifters. One small research reported over two-thirds of leisure resistance trainees confirmed indicators and signs of anterior instability. (6

Not like the fundamental dumbbell bench press or barbell bench press, the hex press limits shoulder extension on the backside of the motion. Your arms can’t journey behind your physique, as a result of the dumbbells are usually not allowed to clear the chest. This function could also be higher tolerated by lifters with purposeful anterior instability. 

As a result of each model of shoulder ache is totally different, these struggling with shoulder points ought to search a professional sports activities drugs supplier — and the hex press could be price discussing, as it could current a chance to coach round or prepare by way of sure shoulder points with the suitable steerage.

Muscular tissues Labored by the Hex Press

As a neutral-grip urgent motion, the hex press trains the muscle mass that flex your shoulders and prolong your elbows. Squeezing the dumbbells collectively additionally trains the muscle mass of shoulder horizontal adduction (i.e. these educated throughout a chest flye) and the muscle mass of shoulder inner rotation. Listed below are the foremost gamers.

Pectoralis Main

You’ll really feel the hex press most profoundly in pectoralis main, the most important, most superficial muscle mass of your chest. The pectoralis main has two main elements — the clavicular head, or higher chest, and the sternocostal head, which composes the center to decrease a part of the chest. Every half contributes to numerous shoulder actions and the hex press covers nearly all bases for coaching your pectoralis main.

Shoulder flexion is resisted through the urgent motion of the hex press. The clavicular head of pectoralis main is educated throughout resisted shoulder flexion. (7) Shoulder horizontal adduction is educated by squeezing the dumbbells collectively towards the highest of the hex press.

Each heads of the pectoralis main are educated throughout shoulder horizontal adduction, together with a handful of various muscle mass. (7)(8) Shoulder inner rotation is educated when the dumbbells are squeezed collectively towards the underside of the hex press. Once more, each heads are educated throughout inner rotation train, albeit the sternocostal head is probably going biased. (9)

Anterior Deltoid

The deltoid is the “cap” of muscle surrounding the entrance, again, and aspect of your shoulder. It’s divided into three purposeful elements, every with totally different actions — anterior, center, and posterior. The anterior deltoid, or entrance delts, flex the shoulder and help with squeezing the dumbbells collectively through the hex press. (7) Whereas typical urgent workout routines hit this a part of the delt, the additional squeeze of the hex press makes this train simpler for anterior deltoid improvement.

Triceps Brachii

The hex press trains your triceps brachii, the three-headed muscle on the bottom of your arms. Along with filling your sleeves, the triceps brachii helps enhance your bench press numbers by enhancing lockout power. For an important triceps pump, attempt three or 4 units of hex press with light-to-moderate weight dumbbells for high-repetition units with 60 seconds relaxation between every set.

Rotator Cuff

Though conventional urgent largely trains muscle mass on the entrance of your chest and shoulders, the motion additionally prompts necessary muscle mass situated deep behind the shoulders— the posterior rotator cuff. (10) The posterior rotator cuff serves a stabilizing operate through the press.

By actively squeezing the dumbbells collectively, significantly through the backside half of the hex press, the deep muscle on the entrance of the shoulder, or anterior rotator cuff, is engaged. Therefore, the hex press seems to be uniquely suited to coach each the posterior and anterior rotator cuff muscle mass.

The best way to Program the Hex Press

The hex press might be programmed in quite a lot of methods on push day, throughout a particular chest exercise, or throughout a full physique exercise. Hex presses can construct muscle and power. As well as, they prime your chest and shoulders for heavy work and work properly for intensification strategies.

As a Low-to-Reasonable Weight, Excessive-Repetition Chest Builder 

Whether or not coaching for constructing muscle (i.e. “hypertrophy”) or power, excessive effort units — these carried as much as or close to muscular failure — are efficient even comparatively with mild weight. (11)(12)(13

Choose light-to-moderate weight dumbbells (e.g. 40 to 70% of what you’d use for the standard dumbbell bench press). Then, take every working set to inside two or three repetitions of failure. Two to 4 units of eight or extra repetitions will promote power and measurement, offered units are carried out with excessive ranges of effort.

As a Light-weight Activation Train

Do you or somebody you recognize endure from the shortcoming to really feel the chest working throughout presses? Don’t despair. The hex press could be the repair. 

Merely carry out one to a few mild units of hex presses earlier than your main press of the day (i.e. earlier than the bench press, incline press, and many others.). Give attention to the “squeeze” through the hex press. Then, like an overfilled shaker bottle, the mind-muscle connection to your pecs will spill over to your main urgent motion.

Maximally squeezing the dumbbells collectively throughout a set of hex urgent might enhance energy output throughout a subsequent set of presses through a phenomenon referred to as post-activation potentiation. (14) This impact could also be particularly interesting for athletes and lifters coaching to be extra athletic. 

As A part of a Big Set

An enormous set is an intensification method consisting of 4 or extra workout routines in collection with out relaxation between. Like supersets, the workout routines used large units can goal non-competing muscle teams or an identical muscle mass.

When all 4 workout routines within the large set goal the identical muscle mass, they’ve been proven to provide related hypertrophy to supersets and conventional units that used 90 second relaxation intervals. (15) However right here’s the kicker — large units take much less time than supersets and conventional units. 

The hex press requires easy tools, minimal setup, and compliments many various large set configurations. Right here’s a pattern large set:

  • Dumbbell Bench Press — 3-4 x 12
  • Dumbbell Pullover — 3-4 x 12
  • Dumbbell Flye — 3-4 x 12
  • Hex Press — 3-4 x 12

Take no relaxation between particular person workout routines. Change dumbbells if vital and instantly start the following carry. Relaxation 60-90 seconds between large units.

Hex Press Variations

In search of different efficient and shoulder-friendly methods to coach the chest? Relying in your preferences and obtainable tools, you would possibly select one of many following variations: 

Single-Arm Dumbbell Ground Press

The dumbbell flooring press generally is a nice train for studying and coaching horizontal urgent actions. In comparison with the fundamental dumbbell bench press, the ground press limits shoulder extension, because the higher arms will likely be stopped by the bottom. The shoulder extension vary of movement of the ground press is much like the hex press, that means it’s prone to reduce stress on the entrance of the shoulder, as mentioned within the Advantages part, above.

One main disadvantage of the dumbbell flooring press, nevertheless, is that it’s normally restricted to mild dumbbells attributable to troublesome setup. Performing the ground press one arm at a time (“unilaterally”) helps to reduce this downside.

Carry out the single-arm dumbbell flooring press mendacity in your again, both together with your toes flat on the ground or your legs prolonged out in entrance of you. Start the press with a single dumbbell held along side your chest and your higher arm resting on the ground. Maintain your shoulder blades pinned to the ground as you drive the dumbbell towards the ceiling and decrease with management. 

Incline Hex Press

Restricted analysis suggests the incline bench press might present higher features in higher chest, or clavicular head pectoralis main, muscle thickness in comparison with the flat bench press. (8)(16)

Though we have to be cautious extrapolating these findings to the hex press, lifters wishing to construct their higher chest would possibly contemplate the incline model of the train. The incline hex press is carried out identical to the hex press, besides an incline bench or adjustable bench set to roughly 45-degrees is used.

Hex Press to Flye Press Combo

A possible shortcoming of the hex press is the shortcoming to show the chest to coaching at lengthy muscle lengths (e.g. “underneath stretch”). Enter the flye press. The standard flye press entails urgent to lockout after which permitting the dumbbells to unfold aside in a “flye-like” movement through the downward motion section, thereby coaching pectoralis main at lengthy muscle lengths through the eccentric (reducing section).

For the hex press to flye press combo, get the advantages of the “squeeze” by performing the upward motion section like a hex press and reducing the weights like a flye. Make sure to use lighter dumbbells than standard for this motion, because the eccentric flye is extraordinarily difficult. 

Medication Ball Push-up

Whereas this last variation isn’t a dumbbell press in any respect, push-up variations are criminally underrated. They are often accomplished almost wherever. Higher but, push-ups enhance power and muscle mass equally to the bench press. (17

Performing push-ups together with your palms on both aspect of a drugs ball requires isometric horizontal adduction of the shoulders much like the hex press, whereas coaching by way of an analogous urgent vary of movement. Attempt the medication ball squeeze push-up as a hex press various when dumbbells are scarce, whenever you need to change-up within the really feel of your chest coaching, or when conventional push-ups grow to be too simple.  

FAQs

“Will the hex press construct my ‘interior chest’?”

In bodybuilding converse, the “interior chest” refers back to the fibers of pectoralis main that connect to the sternum. Particularly, these thinking about constructing their interior chest are seemingly most involved with the proximal or most central parts of these fibers. 
Anybody who performs the hex press correctly will let you know they really feel a robust contraction of this portion of the pectoralis main. Though no research have straight examined the hex press, not to mention measured its long-term results on chest muscle thickness, there’s a case to be made for its use as an inner-chest builder. 
Slender-grip urgent tends to point out decrease muscular exercise of the sternal a part of pectoralis main in comparison with conventional or wide-grip urgent. (18) Though the arm path of the hex press resembles a narrow-grip or close-grip press, hex urgent entails the extra activity of maintaining the dumbbells squeezed collectively.
Subsequently, it’s secure to imagine the “squeeze” enhances sternal pectoralis main contraction, a feat lifters could also be unable to perform through the conventional bench press. (19)

“My health club doesn’t have ‘hex’ dumbbells. Can I take advantage of roundhead dumbbells for the hex press?” 

Though metallic or rubber hexagonal-shaped dumbbells are frequent, many gyms have spherical or “professional type” dumbbells. The hex press can be carried out with spherical dumbbells, as demonstrated within the video at first of the article.
Nonetheless, it is more difficult. Spherical dumbbells demand extra exact utility of inward strain to keep away from motion between the dumbbells.

“Why not simply do pec flyes?”

That’s an possibility. Each workout routines prepare pectoralis main, anterior deltoid, and firm. However pec flyes are a single-joint train and fail to hit the triceps brachii, which does obtain a coaching stimulus through the hex press.
Machine pec flyes and cable crossovers can be extra taxing on the shoulders, particularly amongst lifters with purposeful anterior instability from a earlier damage or cumulative trauma. This pathology is mentioned intimately within the Advantages part.

“Are you able to clarify extra about why hex press is considered ‘shoulder-friendly’?”

The radius of the dumbbells offers the impact of a board press, which limits urgent vary of movement. Particularly, shoulder extension is restricted. People with sure shoulder accidents, resembling purposeful anterior instability, might not tolerate loaded shoulder extension. Therefore, the hex press could also be an acceptable possibility. 
Diving deeper, purposeful anterior instability is considered associated to decreased exercise of subscapularis — a muscle of the rotator cuff. (4) Squeezing the dumbbells collectively on the backside of the hex press elicits sturdy contraction of the subscapularis. This function would possibly enhance  tolerance to train or assist handle subscapularis insufficiency. 
Usually, hex urgent tends to be higher tolerated than pec flyes and conventional bench press variations by these with banged up shoulders. Once more, go see a professional sports activities drugs practitioner should you’re coping with a shoulder damage.

 

Construct a Magnum Chest with the Champagne Press

The hex press is carried out by aggressively squeezing dumbbells collectively all through a neutral-grip dumbbell bench press. The squeeze engages higher parts of your pecs, which can result in accelerated chest features. The hex press additionally reinforces necessary components of urgent method, spares sore shoulders from loaded hyperextension, and creates co-contraction conducive to joint stability. Savor the squeeze and have a good time the hex press.
