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.
If you’re just starting out, aim for two sets of 8 to 12 reps of the heaviest weight you can handle for each exercise. Looking for more of a challenge? Shoot for two sets of 15 to 25 reps per exercise.
