I see people who barely lower the bar and some who lower dumbbells below their chest, I was just wondering what the benifits are from doing it different ways.
80% ROM or so....cut out the top 10 and bottom 10%
The chest is only activated through a certain part...going down to your chest and touching...shoulders come in big time, the top end of it is a lot of tricep.
Depends what you are training for
Down all the way.
For me, each rep begins and ends with the barbell resting in a rack position (upper chest/clavicles).
My grip is thumbless and is right where the knurling meets the smooth part of the bar. Going wider would be for those who don't go down as far.
