I literally think that if your a good runner here, you should have success in the gym. First of all I would go to the gym wearing a marathon race tee shirt, which shows that you done one. She will be impressed and know straight away your a true athlete with endurance and commitment. Go on the threadmills beside girls you like and start running. I would put the threadmill as fast as you can and run for a long time. She will be amazed. Also were lycra leggings which literally reveal the shape and size of your junk. Girls will love to look at you and it will make them want you. Go over to the weights machines area and adjust the weights to the heaviest settings. You don't have to use the machine(I do this all the time and every one is gobsmacked. Just sit there until a girl literally comes up to you to use the machine. Tell her something funny like "I'm glad you came over to kick me of this machine, this workout was killing me and I literally needed a excuse to get of". She will think you are funny, humble and very extremely super humanly strong at the same time(because the weight is literally on the highest setting. I would also give them as many compliments as possible. For the runner girls on threadmills say you remind them of Almaz Ayana. For any other girls tell them funny witty and charming things with compliments. Example, Bekele lifted the world of running with his best achievements, but he hasn't lifted them weights like you have. You have lifted my heart, and that is evan better then his world records. Make general conversations to on interesting topics, like Bekele getting the marathon world record this year etc. Also near the end of your session look for a lose weight on the ground near a girl you like. Purposely walk into it and trip over to pretend to hurt yourself. The girl will come up and try to help you. Tell her that falling in front of her is like falling into Almaz Ayana or Dire Tune's hands. Tell her that the Ethiophian godess's don't match the godess in this gym, you. Ask for her number and tell her you want to bring her out as a thank you for assisting you when you literally fell.
