and i now all about it cause i was avid bencher for years

you arch cause u're protecting shoulders, u're basically turning bench into decline because it is retarded injurious nonsense and it requires u to arch - low crossover with PROTRACTED shoulder builds pecs all the way to sternum unlike bench cause when your shoulders are retracted most of pec is switched off being strung on ribcage

>what does it have to do with low back pain during retarded insjurious nonsense that bench is?
u arch with your psoas, u pull lower spine with psoas into hyper-extension as your pelvis and legs are fixed, it simply cramped like your calves when u r dehydrated and point toes and drag heel

>>he thinks side delts perform shoulder adduction
>kek
when db is past your shoulder u're fightin it falling across your body and that is horizontal abduction which is side delt to a degree

doesn't matter, if load is beside u and shoulder is protracted u'll get pecs - with low crossover (pictured)

bench is retarded cause pecs are wrapped around ribcage if your shoulders are retracted switching most pec muscle fibers off - that's how u get bitch bench tits cause costal head of pecs have somewhat of a chance to work

yes dumbbell bench-press is the same in that aspect

it doesn't matter one bit
>how so?
cause bench is injurious retarded nonsense* so u do not do it, u do crossover, unilateral low crossover with protracted shoulder, preferably as isometric hold
and then u can do whatever u like for front delt

*cause shoulders must be retracted and such alignement wraps pecs around ribcage switching most of it off
ever wondered why benching pecs tend to look like squashed carboard box? that's why, only costal head of pectoralis major has a chance to contract properly

that will be yes

ir's dumb, u are dumb

way ahead of you :D

>>>just reduce your total work by 25-50%
>In physics, work is done when a force causes a displacement. Isometric holds, however, involve muscle contractions where the muscle length and joint angle don't change, meaning no displacement occurs. Therefore, no work is done in the physics sense during an isometric hold.
>While the muscles are working isometrically (maintaining tension), the lack of movement means no energy is transferred to displace an object. Therefore, even though the muscles are experiencing tension and fatigue, no work is done on the external environment.

what's the logical fallacy u're employing here bot? u're using "work" in physics sense in the context of human body where resistance to external force is counted as zero - clearly false

there was always this unspoken conclusion that
>well if u do half the motion your muscles are gonna get stiff short and will look funny
and it's bullshit, it's the other way around, if u actually USE muscle in perfect setting for the muscle to contract it grows big healthy and does not shorten or stiffen

take benchpress as example: benching requires u to retract shoulders and while actively benching elbow is behind torso - most of pec will be switched off during pushup/bench, only costal part is not snagging on ribcage and u wind up with mangled bitch bench tits with void in the middle and under clavicle - pecs can't be used in full and as they grow mangled and weak in parts they stiffen and shorten
how should u bench then to load totality of pec? like jay cutler - halfreps with protracted shoulders

or do not bench at all, just do low crossovers for pecs, and skip the
>imma press now
part and stay in isometric hold, u ain't gonna turn into toad if u do i promise, all u're gonna do is load whole muscle of pectoralis major with continuous time under tension on muscle belly
