Developing Lower Pecs

Okay, so since I have a thing where I get upset when people tell me what I already know (but people don't know that I know,) let's assume that I know nothing about body building.
That being said,

I need help on lower pec development.
What type of training do I have to do?
Right now, my pecs are in the form of a V, like sports sunglasses and it's not a pretty sight

tips please?

 

Lower Pecs.. Hmm: try bench pressing, but spread your arms out a bit more, I know that creates more tension, but I've never had this problem, so I can't be sure..

 

When you bench press do Decline and go wide grip and vary it with regular benching and very wide grip.

 

Lower pec = decline bench press
Upper pec = incline bench press

 

Decline Dumbbell/Bench Press will do great work on the lower Pecs.
Flat Dumbbell/Bench press will also help develop size in order to tone/shape those pecs.

If you do not have access to a gym, there are other efficient ways to build muscle at home
Sample workout for Isolating Chest:
Exercise - (Sets x Reps)

Triangle Push Ups - 3 x 10
Regular Push Ups - 3 x 10
Wide Grip Push Ups - 3 x 10
Spiderman Push Ups - 3 x 10

Perform these at an even pace, no need to rush
This should be more than enough to give you a heated up, pumped and aching chest feeling. If this gets too easy, increase repetition and sets.
Reminder: Range Of Motion is VERY important.

Feel free to ask me for further advice.
