Can men and women do the same workout for abs ?

I ve been working out with my husband for the last 2 weeks. we are been doing crunchs and push ups together, and also we have been working out using the swiss ball. He does like 30 crunchs non stop and expects from me to do the same,the push ups he does countless and I stop at 5, I just can’t do much, Im not even flexible to do what normal girls do lol. My question is are girls and boys supposed to do the same workouts for abs?? boys need a huge six packs while girls need just flat abs.
