Sorry for the graphic depection. However, an old (age) friend of mine told me that I need to watch it when I am doing squats. He told me about his lifting days and the "bacon" (hemroids) that he had after heavy squts.
1. How do you get them?
Straining on the toilet, poor diet and not enough fiber.
2. How do you avoid them?
your answer is in the first question.
3. Are the genetic?
No!
4. Anyone have them and can they give history about them?
Bro, roids are common believe it or not. Roids can form in your ass or along the outer part of it. Creams and such do work but if you have them bad, surgery is required. Roids can take as much as 4 weeks before they are gone.
I have not had them but worry about them after he told me this story. He told me on AS you are more prone because you can lift heavier than normal. I know that I need to lift heavy for mass - man what a choice to make . . .
