Can't tell if she just wants attention or wants to be approached.

She's 5-10yrs older.

At the park I do pull ups, dips, abs. I see her once in a while. She always jogs a little then comes to my area to do her stretches on one of the machines. The stretches are pretty slutty. She stares quite a bit.

I've been waiting for an excuse to chat with her but nothing has come up yet. What would you do?
