After baby (even if baby is now 4 years old). This workout will tap into the deep abdominal muscles that will pull in your waistline like a corset. Do these moves one after another with no rest in between. Then repeat once.
For after baby. Someone said: "30-day ab challenge. I just had to repin this because I've been doing it for only 4 days now (and at only 10 reps instead of 25) and already I'm seeing definition. And I've tried pretty much every Ab workout on pintrest and haven't seen these kind of results."
