Can I train my abs during pregnancy

The usual crunches and exercises for the rectus abdominis aren't done during pregnancy — as the bump grows that kind of load stops being appropriate.

Instead you work with breathing, the deep muscles, the pelvis and the back. That's what preparation for birth and an easier recovery afterwards actually looks like.

The pregnancy schedule simply doesn't contain those exercises — the plan is built around your trimester, so there's nothing to strike out by hand.
