Man, I goto the gym... get my lift in... and get the fuck on... one thing I learned about picking up hoes at the gym is that if they want you they'll approach you or it will be so blatantly obvious that you'll know they want you...
True story
I'm at the gym a few years back and I notice this chic walking back n forth in front of me when she could have EASILY walked around to get to where she was going... I paid her no mind at all... kept lifting, nodding to my music... she then started inching over closer and closer to where I was working out and being real extra in her movements... still, paid her no mind...
The chic went into the dressing room and changed clothes... came back out in those little super short, kinda loose Nike running shorts.
She came back to the bench next to me, grabbed some dumbbells, turned her back to the mirror we were in front of and started bending over doing hamstring exercises (good mornings) and other stretches in front of me. I noticed at this point she had taken her panties off too because I could see the lips hanging out every time she bent over... this is when I got caught slipping and she saw me looking in the mirror while she was bent over... still, I didn't do anything I just smiled, shook my head and kept lifting... after teasing me for a few more minutes she went to the back, showered, came out in street clothes, walked over and showed me a meme of Rhianna biting her lip with a caption saying something about the "fine nigga in the gym wearing grey sweatpants," then tried to hurry and walk out.
At that point I finally paid her attention... got up, walked her out, and got her number and planned a few workout sessions with her. She was like "I did everything to get your attention and you wouldn't even look at me."
Like I say, if a gym chic wants you, you'll know it...
