FROM LAB TO GYM: Focus on the Smith
HYPOTHESIS Although research confirms that the free-weight bench press allows you to use more weight than the Smith machine version of the exercise (due to the unnatural path of the bar on the Smith), we still recommend you make use of the latter because it places greater focus on the pecs.
RESEARCH Researchers from California State University, Fullerton, measured the muscle activity of the middle deltoid, front deltoid and pectoralis major (pecs) when subjects performed bench presses with free weights and on the Smith machine.
FINDINGS As reported in a 2010 issue of the Journal of Strength & Conditioning Research, there was not much difference between the muscle activity of the pecs and front deltoids during either version. However, the muscle activity of the middle deltoid was more than 60% greater on the free-weight
bench press than on the Smith machine.
CONCLUSION This increased activity was due to the greater stability needed to balance the free-weight barbell as opposed to the fixed path of the Smith machine.
APPLICATION Use the free-weight bench press to go heavier and place more overload on the pec muscles to stimulate greater overall upper-body growth. However, include the Smith machine bench presses to place more emphasis on the pecs, which will also help to stimulate greater growth.

FROM LAB TO GYM

Ja sam pre 3 nedelje poceo da radim smith kosi bench ali spustam sipku jako visoko milimetar ispod brade. I evo po prvi put od kad radim grudi da imam nekog napretka i da osecam taj gornji deo grudi razvaljen posle treninga.

Najvise osetim misice gornjeg dela grudi kad skupim lopatice tako da mogu da dobijem sto veci stretch u grudima na negativnom delu ponavljanja i onda sto tecnijim pokretom krenem u pozitivni deo ponavljanja.Laktovi se ne ispravljaju do kraja vec skoro da zakljucavanja.Znaci samo tecni kontrolisani pokreti uz dobro istezanje grudi kad se spusti sipka i da vis' kako gori.

da svi rade kao sto je urlich opisao ne bi se zalili na "pilece grudi". Retko vidjam ljude da rade u teretani bilo sta pa i grudi kako treba, guraju tezine i vezbaju ego 80% vezbaca je tako...
Ja sa svakom vezbom super pogodim grudi, sad omiljene su mi kosi, ravan bench ali sa bucicama, i naravno razvlacenje, sajle, ma sve zivo, bitno mi je da mi je svaki sledeci trening drugaciji po necemu od drugog i to je to. :)
