You can't only target one fiber type, that's a complete fallacy.

So to sit here saying you "kill one type of fiber" and then proceed to "kill the other" with a set of lighter reps is moronic.
And tadow, no, everyone isn't so different that the basic principles of physiology don't apply to them. There are universal rules to everything. Everyone is different, so does gravity not apply to you, but it does to me? No. So why is it different with physiology? Calories in vs. calories out applies to everyone as well, in terms of weight gain and weight loss. And when it comes to lifting, progressive load and microtrauma to muscles also applies, and more progressive load is possible with movements such as heavy presses while causing more microtrauma which is why (surprise, surprise!) they're ideal for building muscle.
Shit like flys and cables don't leave a lot of room for progressive loading. And your reason for doing them, patsfan, is to "sculpt" and "stretch". Okay, you can't sculpt a muscle. You can NOT change it's shape. You can make it bigger, or it can get smaller. The shape is determined by genetics. That's it. You can't develop different parts of the muscle. That doesn't happen.
As for stretching, okay, that's fine. You don't need to "stretch" that much though. Too many sets. And I don't see why you'd stretch during a training session. It's actually been shown to decrease performance. You'd be best off doing that on an off day for active recovery, in order to get blood flowing into the area.
needtogetas, get the fuck off the training boards. Seriously, you're like a fucking little parasite. Go sit on C&C and do your own little thing, because here you're lacking some of the most basic knowledge and fundamentals of lifting and you can't even begin to contest with anyone.
