I go jog at a nearby park almost every day. The place is full of beautiful women walking or also jogging. how can i open in this situation? any suggestions?

I've wondered the exact same thing. I run almost daily around a lake near my house, and its a popular spot; there's always a crowd of cute girls. Getting them to stop and talk seems tough, everyones into their workout. Fake an injury maybe???

Make sure you're moving in the same direction as the woman, or that she's not moving at all. Ignore you until you get close, then make eye contact. Without losing eye contact, go right up and talk to her. My favorite opener here is a simple "Hi, how are you?" Know that if you're not completely comfortable and confident with yourself, these aren't easy openers - but if you are, they're money during day game (at least for me).

That said, make sure you dive into the usual false time constraint, etc. etc. Afterwards, make sure you make a statement of interest and pull the trigger on your goal for the interaction. Usually in an exercise-type SPAM a number is the endgame.
