Narrow grip. The clavicular fibers of the pectoralis major are for shoulder extension.
Wide grip = adduction which is for the sternocostal fibers.
Intermediate between the two for a combination of both fibers.

> extension
Oops. Meant flexion. The sternocostal fibers assist in shoulder extension whereas the clavicular fibers don't.

yeah except all tension must go through front delt first and it will die first and u get no pecs

yeah u don't have a clue what u're talking about - pecs are wrapped around ribcage - they are misfireing in fraction of muscle free of ribcage only, the one thing that is constantly working is front delt, which will die first and u get no pecs
to get to pecs shoulder must be protracted and elbow must be in front of u - 2 things that never happen during pushup
>but elbow goes in front of u in pushup
when u lock out, when u don't use pecs anymore, when pec sorts itself out from unwrapping from ribcage and resulting slack in muscle
>yeah i get it, u should be doing like quarterreps in the top of the motion only with slightly protracted shoulders like jay cutler "benches"
that's why he does it yes, it's still retarded and front delt dies first and u're gonna fuck ur shoulders and get no pecs presuming u're not on horse dose of roods

do u really must push with both hands at the same time? in this faulty for pecs plane?
