you need a good looking face first and for most, the more fit you are I feel like the more your look is scruitnized, like some kind of failed potential.
although being in good shape and leading with that usually works with simple looking and acting chicks, girls with uniqe attitudes and options tend to be more choosy cause most people know a good body doesnt mean good in bed (which is what your body is gonna be used for in the first place)
Fun fact: you can practice sex positions as a work out, hitting a whale stroke in the missionary position for 30-60 seconds will have your core, arms, and shoulders on fire
