Tiež máte zimu spojenú s carvingovými oblúčikmi, jazdou po spádnici alebo neodmysliteľným relaxom v apres ski bare? Pokiaľ milujete pohľad na zasnežené hory rovnako ako zimné športy – nech už sú akékoľvek – máme pre vás tip, ako si tento zážitok užiť na maximum.

Skrátka tak, aby ste naň dobre videli!

Keď sa povedia zimné radovánky na horách, väčšina z nás si vybaví kvalitné oblečenie, ktoré zvládne mínusové teploty, studený vietor alebo snežnú víchricu. Často ale zabúdame na ďalšiu dôležitú súčasť výbavy - slnečné okuliare. Bez nich si totiž v nadmorských výškach môžete v lepšom prípade privodiť zápal spojiviek, v tom horšom aj trvalé poškodenie zraku.

Slnko je v zimných mesiacoch položené na oblohe nízko, to znamená, že koncentrácia UV žiarenia vstupujúca do oka je oveľa väčšia. Je to dané snehom a mrazom, z ktorého sa lúče odrážajú. Kvalitné slnečné okuliare tak majú za úlohu predovšetkým odfiltrovať UV žiarenie, ktorého intenzita rastie so vzrastajúcou nadmorskou výškou. A to nielen na horách, ale aj počas bežných každodenných aktivít, ako je napríklad riadenie auta,“ opisuje optometrista Martin Slaný, odborný očný garant FOKUS optik.

Ako vybrať vhodné slnečné okuliare? „Je dôležité, aby okuliare boli pohodlné, netlačili a ich hmotnosť sa rovnomerne rozkladala na uši a nos, najmä ak sú určené na dlhodobé nosenie. Pred ich nákupom ale vždy zvážte, pri akých príležitostiach ich chcete najčastejšie nosiť,” vysvetľuje Martin Slaný.

Nie sú okuliare ako okuliare

Klasické slnečné okuliare chránia oči pred oslnením, ktoré je na jeseň a v zime horšie ako v lete. Športové modely sú ale navrhnuté tak, aby okrem UV ochrany zaistili bezpečnosť zraku najmä pred mechanickým poškodením, napríklad pri nepríjemnom páde. „Športové okuliare by mali zakrývať oči po celom obvode, čím chránia zrak nielen pred svetlom, ale aj vetrom a cudzími telesami. Výhodou je tiež skutočnosť, že sedí bližšie k tvári, takže je v nich citeľne teplejšie,“ objasňuje Martin Slaný.

Zamerať by ste sa mali aj na sfarbenie skiel. Na snehové športy sú ideálne hnedé, jantárové alebo žlto sfarbené šošovky, ktoré zvyšujú kontrast a lepšie v nich vidíte detaily. Šedé sklá zase pomáhajú znížiť intenzitu svetla, ale zároveň pritom neovplyvňujú kontrast ani neskresľujú farby. „Zaobstarať si môžete aj okuliare s vymeniteľnými šošovkami a tie na základe počasia a viditeľnosti striedať podľa ľubovôle,“ dodáva Slaný.

Alternatívou môžu byť aj kontaktné šošovky

Pokiaľ bežne nosíte dioptrické okuliare, oplatí sa pri zimných športoch investovať do kontaktných šošoviek. Niektoré helmy síce majú vymeniteľný ochranný štít a širšie bočnice, aby ste si mohli nechať okuliare nasadené, avšak pri páde hrozí, že vás bežné okuliare môžu poraniť alebo si ich môžete poškodiť. „Najlepšou voľbou je zaobstarať si jednodenné kontaktné šošovky, ktoré večer po použití jednoducho vyberiete z oka a vyhodíte,” uzatvára Slaný.

Športové modely sú v kurze aj mimo hory

Rámy inšpirované športom sú pritom trendom aj pre nadchádzajúcu sezónu, ako bolo vidieť aj na prehliadkovom móle na milánskom týždni módy. Najmä tzv. modely Racer, ktoré sú typické svojimi hranatými tvarmi a výraznými farbami, budú hitom jari a leta 2023. Využijete ich tak ako na zjazdovke, tak aj v meste.

    This is probably the most fundamental variation of these three and it’s a great option for newbies starting to be taught
    the bench press and lifters that wish to construct their pecs
    in totality. The first and most foundational difference between the flat,
    incline, and decline bench presses is that each variation will entail a
    different bench urgent at a unique angle. When discussing which bench press variation is "best" or "better" we need to
    apply context to what we’re asking. For instance, the flat, decline, and incline bench presses will
    be better than one another depending on your targets.

    You can carry out flies from each an incline and a flat position. Unlike
    presses, in flies your arms stay in a exhausting and
    fast place without bending your elbows. You can hold your elbows slightly bent all
    through, however shouldn't be bending repetitively.
    As the name implies, incline presses are carried out along with your body in an inclined position.
    With dumbbells, you may get a larger stretch and squeeze in your
    pecs (you can deliver them closer collectively at the prime of the movement,
    which forces your chest to contract more). We’ve already went over all
    you should know about the standard grip flat bench press.
    If you need to learn to do it, scroll as much as the 'How To Do A Bench Press' part.

    There are numerous variations of the bench press that can be utilized to target specific muscle groups or
    weaknesses. The flat bench press primarily activates the upper,
    center, and decrease chest and the triceps. It also engages the anterior delts, traps, forearms,
    lats, muscles of the rotator cuff, and rhomboids. The incline bench press is a superb accent movement for
    many who additionally flat bench press. If you are utilizing
    each exercises in the same session, it’s a good idea to do the flat bench press first, adopted by the incline bench press.
    Both workout routines are great for targeting the chest, shoulders, and triceps.

    For instance, in case your higher chest just isn't the place you need it to be from
    an aesthetics standpoint, an incline bench press will be
    the solution to your issue. Or, if you have pre-existing shoulder pain or tightness,
    then manipulating the angle of the bench
    might permit you to nonetheless perform a pressing
    motion safely. The incline bench press is often programmed on chest, higher physique,
    or push days. Although you'll find a way to practice the incline
    bench press within the 1-5 rep vary, the 8-12 rep vary is ideal.

    If aesthetics is your goal, lifting within the
    1-5 rep range isn’t going to be probably the most advantageous
    method to prepare.
    You additionally have to be aware of its right approach to
    keep away from accidents. The bench press
    mimics pushing movements utilized in sports activities and every day life, similar to throwing, shoving,
    or shifting heavy objects. Have you ever puzzled why so
    many individuals wrestle to get up from the dumbbell bench press, even once they appear robust enough to lift?

    This common dilemma highlights the significance of bench press...
    Dumbbell presses sometimes provide more flexibility in movement,
    which can reduce joint pressure. However, correct kind in each presses is
    important for joint well being. Bench pressing can permit for heavier weights,
    which may be efficient for constructing mass, however both methods may be
    equally environment friendly with correct training.
    The key to gaining these benefits is to remain constant, maintain yourself engaged via its
    variations, and follow a healthy life-style.

    So as you'll find a way to see there is not any actual science
    to calculating your barbell bench press based mostly of your dumbbell press.
    However you can figure it out easily by starting mild on your bench press and rising
    from there.
    You might want to focus much more on stabilizing the barbell as you lower it and press it.

    This is great for activating your main movers differently, but more so it
    increases the demand on all of your stabilizing muscles.
    This is an efficient way to develop total power that will translate to stronger more steady commonplace presses.
    Your arms should be at about 45˚ out of your torso
    when doing a standard flat bench press.
    Isolating the chest with pre-exhaustion strategies before presses can intensify muscle workload.
    Start with flyes before urgent movements for a sophisticated muscle-building
    strategy. Switching between dumbbell and barbell presses can maintain muscles guessing and
    advancing. Periodize coaching, oscillating between quantity and intensity phases
    for sustainable progression. Focus on keeping your wrists straight so
    that they're perpendicular to the ground all through the exercise to stop wrist harm.

    No, the dumbbell bench press isn't harmful if the athlete uses the right type and lifts an applicable amount of weight.

    One of the primary benefits of the dumbbell bench press is the larger
    range of motion. To maximize this profit, the load must be under your chest
    on the backside of the press. At the highest of the press, you want to
    convey the dumbbells together.
    Until your performance is going to be assessed using
    the flat bench press, it’s not an absolute necessity to aesthetically develop the higher physique.

    A good alternative is the incline bench press, especially since you can regulate the angle
    to focus on particular areas of the chest. If your higher chest is lacking in improvement, it’s a good idea to focus on getting stronger on the incline bench press somewhat than solely flat benching.
    Furthermore, an incline bench press is better if your aim is to step onto a bodybuilding stage
    or you’re more concerned about aesthetics quite than energy or efficiency.
    Not Like the more conventional flat bench press, the incline press
    shifts the movement's focus to the higher portion of the pectoral muscle groups and the entrance of the shoulder.
    This allows for more vital hypertrophy (muscle growth) of the upper
    chest when the exercise is carried out often.
    Sure, you'll find a way to incorporate each the incline dumbbell press and the flat bench press into the same workout routine to target
    different areas of the chest.
    Starting with the Dumbbell Press, focus on a full range
    of movement. The incline press could be problematic for
    many who expertise shoulder pain. If you have ongoing shoulder ache, attempt the train on a machine or with a barbell before attempting it with dumbbells.

    Firstly, flaring your elbows introduces internal rotation into the movement.
    Brace your core by taking in a deep breath and pushing your diaphragm
    outwards earlier than each rep. This stabilizes your torso.
    By incorporating each, you’ll build an even bigger, fuller, broader
    chest and achieve the eye of all onlookers. In a gym,
    you won’t need to look onerous to find
    an adjustable bench, so you'll find a way to decide and choose your angle.

    Tuck your elbows slightly in in direction of the torso
    to permit you to stack the dumbbells instantly above your elbows.
    2– Subsequent, push the other weight up whereas bending your other arm.

    Some key cues, which you’ve in all probability gather by now are, you need to decrease the bar to your neck stage and your elbows
    must be course beneath the bar, so they are going to be at 90˚ along with your body.
    In addition to the dynamic muscular tissues of the raise that we simply went over,
    you have stabilizer muscles... Your forearm must be perfectly vertical
    when the bar touches your chest.
    So, when selecting a weight load, you would possibly be primarily
    catering to your power in the backside range of the movement.
    With partial reps, you are catering to the highest range solely, so you possibly can go heavier.
    Lifting weights isn't all about your muscle tissue, it’s about your bones too!
    Lifting weights is nice on your musculoskeletal system as a complete.


    By lifting heavy hundreds, your bones will get denser and stronger.

    Considering your strongest higher physique carry
    will be the bench press (without question), then there isn't any better train for upper body bone well
    being than the bench press. This will maintain your upper
    back flat and your shoulders stable throughout bench presses.
    The squeeze of your shoulder blades ought to happen even earlier than you unrack the bar.

    The third distinction that I wish to touch on in this article
    is the talent necessities that come along with the flat, incline, and decline bench press.

    As I get heavier I plan on switching to dumbells but I'm
    wondering if this can put me at any type of disadvantage.
    This train not solely lets you work one arm at a time, however it'll also enhance
    coordination and core energy. It’s an excellent train for muscular endurance and works well when used as a half of a
    fat-burning circuit exercise. 2– Bend your arms and decrease the weights till the again of your arms frivolously contact the ground.

    The chest fly is a great exercise to make use of if you would like to substitute
    the dumbbell bench press because it impacts your chest in addition to different
    body elements. It is a compound carry and works your entire upper physique,
    together with your pectoral muscles. If you follow these steps,
    you will shortly grasp the correct form of the dumbbell bench press.
    Incorporating this exercise into your exercises will help you
    quickly construct a robust and outlined higher physique.

    Like all weightlifting workouts, an athlete must carry out the dumbbell bench press with correct form and technique.
    The good type ensures that the athlete gets essentially the most out of the motion, maintaining
    them protected from potential injury. Sure, the flat bench press could be
    carried out by newbies; nonetheless, it’s essential
    to start out with lighter weights and focus on proper type.

    Conversely, the bench press typically permits heavier lifts, leading to potential mass positive aspects, and serves
    as a benchmark for energy. Both have distinct advantages tailored for diverse objectives, and integrating both can lead to
    a comprehensive upper body growth. Sure, dumbbell presses may be an alternate, focusing on stabilizing muscular tissues and providing variation, but
    shouldn’t completely replace bench presses if
    looking for maximal energy gains. Generally speaking,
    superior lifters should be ready to flat bench press with dumbbells that weigh 120 to 140% (both dumbbells combined) of their physique weight for a single repetition. Whether you are bored of
    barbell bench presses, or just want to add some
    variation to your higher physique workouts, the dumbbell bench press is an effective choice.


    Overall, the emphasis will be in your upper, inner and outer chest in addition to your triceps.
    Wide grip barbell bench press is around 2x shoulder width apart.
    This could have your elbows at a little under 90˚, which is secure in your shoulders.
    As you lower the bar down, your elbows will be saved instantly underneath
    the bar. Shut grip barbell bench press has your shoulders at about shoulder width apart.

    This may have your elbows close to your torso and out slightly in entrance of the bar if you
    decrease the barbell down.
    This switches you from eccentric-concentric contraction to isometric contraction. General, it is
    good for constructing power, as isometric contraction is nice for getting stronger.
    With resistance bands, the more they stretch, the extra resistance they've.
    With that, within the backside range of the bench
    press, the band has much less tension, virtually to a negligible point, so the burden load just isn't
    really more difficult than it normally could be without the band.
    Nevertheless, as you press up, the band stretches, so if you reach the mid to top range, the band provides resistance so what would usually be the
    better a half of the carry turns into harder.
    Particularly, the barbell bench press is amongst the Huge Three
    in aggressive powerlifting, alongside squats and deadlifts.

    This is as a outcome of with squats, deadlifts and bench press, you might have a transparent image
    of overall total physique energy. As such, the
    bench press is taken into account the ultimate higher body exercise.
    One Other difference is the muscle tissue, and more particularly, the
    pec fibers that every variation will assist train. A large cause for using flat, incline, and
    decline bench presses is they can be great for biasing the different muscle fibers of the pec main. If you are solely
    going to do one bench press exercise on your chest muscular tissues,
    the flat barbell bench press might be the better alternative.
    It works each your upper, middle, and decrease pecs in a protracted range of motion, and is confirmed efficient for constructing an enormous chest.

    Lower the bar so lengthy as you probably can while nonetheless maintaining an in any other case correct kind and don’t expertise
    any discomfort. The objective is to work your muscle tissue by way of
    an extended range of movement, and if you lower the bar until your chest and shoulder muscular tissues are fully stretched, that's long sufficient.
    For a lot of people, this shall be when the barbell touches the chest,
    however not for everyone. Your anterior deltoids
    (aka front delts) are activated to a higher extent within the incline bench
    press.
