Soy doesn't actually have oestrogen in it it has a chemical that's very similar, no it can't give you trap features but it can slighty increase the risk of cancer.
What the kike quacks who push that tranny shit always neglect to tell their victims is pumping your body full of hormones is very harmful and your body tries to overcompensate to fix it which can result in the growth of tumours and cancer cells, due to the "fake" oestrogen like chemical it can do the same but I doubt the same degree.
Consuming Soy based products is mostly fine, I mean you don't see jap falling dead constantly due to cancer and they eat it more then anyone else.
As for exercise routines squats and lower body based exercises, for more indepth be best to go ask /fit/ do we even have a /fit here?
