How can i work them without weights?

[Matrix0978]

Push ups.

Pull Ups.

Why no weights?

Pushups will help with your muscular endurance in the entire upper body, also great for the pectorals.

[fangshi]

dips help too . You can also vary the resistance of the push up by elevating the feet or using 1 arm . (lots of other variations too ) .

Pushups: The closer you place your hands, the more emphasis on the inner pecs, the wider you place them the more outer pecs are emphasized. Also, if you keep your elbows close into the body rather than at a 90 angle, you will work your triceps more than anything. You can also elevate your hands on boxes to allow a deeper, fuller pushup. My favorites are wide pushups on boxes,and "marine" pushups. (Place hand in a triangle formation close together, dip until your nose almost hits your hands, then push forward and up, and then reverse your path.)

Dips will work your chest if you lean forward while doing them, otherwise they emphasize the triceps more.

Pullovers (Lay on your back, with your arms straight pull a weight up and over your chest from above your head.)

Not sure why you want to do it without weights, there are lots of cheap weight sets available that would help immensely.

I'd do Abs too, because it is considered your core. Dips pushups and pull ups i'd do. I'd suggest working all the muscles around your pecs and your pecks. Just working one group of muscles will cause an unbalance in all muscle and may cause future problems.

Pushups for endourance; you need to add weight (backpack, or do bench press with weights) for strength gains.

Pex? Oh, you mean pecs. As in pectoral.

[KarateKid7]

can you do isometrics to stimulate pectoral hypertropy...im reffering specifically to dynamic strength by Harry Wong - people hu have read this will know wat im on about.
