Getting a number at the gym?

okay so i had already implemented the pickup strategy on talking to her by saying if she ever needed help with the heavier weights she could tell me and then I introduced myself and she did 2. Then left it alone for about 2 weeks but inside of those 2 weeks there was a hi and bye . And then towards the end of those 2 weeks I stepped it up to walking along side her and slightly tapping her arm and saying wassup how you been and she said ive been good and u . I said the same and told her in a confident way to have a good workout , and now she gives me the googly eyes with a shy face when i look at her so what do i do from here? I REALLY NEED YOUR GUY'S HELP!
