I'm hopping onto the second week of 5/3/1 and I'm going to put my girlfriend on it as well since we go to the gym together anyway

I was curious if the monthly weight increases should be lower for women? eg 5+ upper body 10+ lower monthly?

also thoughts in general on girls doing 5/3/1?

Thats... how it is. 5 upper 10 lower

Keep the program the same. Her progress will likely depend on how seriously she takes the routine.

i would suggest putting her on ss then fuck her right in the pussy
