bodybuilding exercise: dumbbell press for chest

[mjacobs023]

white fibers = fast twitch

Red fibers = slow twitch

fast twitch fibers are 30% bigger than slow twitch

If you work your fast twitch fibers out you will gain massive size compared to building slow twitch fibers.

How do you build fast twitch? by using EXPLOSIVE movements with heavy wieght.

when i did these i found more of burn in my arms than anything (a little in the upper chest as well however).

my elbows were in line with my shoulder. might i be doing these incorrectly

[xxdeathlokxx]

Nah, you've just got more strength in one place than the other, leading to the burn in your arms coming first. As you get caught up with your chest, it'll be more of an over all workout, I believe.

he is going slow to show proper form, plus speeding up is just making it easy and untidy. Good video, i used to have dl press but grown to like it lately

[TVstudio]

Why are you going so slow?

[Kiddowesth]

He's going slow because he is controlling his form, and not tosing the weights around . This makes sure that he is working the section he's aiming at .
