"When we're seated, our back muscles and spine help keep us upright and the abs are in a slack position, especially if you slouch," explains Joseph Herrera, a doctor of osteopathic medicine and the director of sports medicine at Mount Sinai School of Medicine Department of Rehabilitation Medicine in New York City. "Although we would end up reclining without the opposing muscle forces they provide, intentionally contracting your abs is the only way to activate them as you sit." As I stand in his office, Dr. Herrera tapes electrodes beneath my rib cage and just above my belly button. Cables connect those electrodes to an electromyography (EMG) machine, which makes a whooshing sound every time the underlying abdominal muscles — my external obliques and rectus abdominis — are activated.
That depends. It doesn’t matter how hard you train your abs if you have fat lying on top. Cardio gets rid of that fat, but if you’re already thin with a low body fat percentage and/or have a fast metabolism it’s unlikely that you will need it. If you do have fat and want to do cardio, first decide what kind of cardio you’d like to do (steady state vs. HIIT). For steady state I’d recommend something like 5 times a week, but for HIIT I’d recommend no more than 4 times a week (every other day). If your HIIT workouts are under 12 minutes then feel free to do them more times a week.

I work in a specialty running store in Maryland. I took the job because I love running and I love my boss. I tell you this because this month, Caitlin and I have been using your 30 day ab challenge and we have had so much fun. We are looking to continue it through the year though and would love your suggestions for do that. I am not sure just doing this one over and over is the best plan.

To ensure your plumbing is working at optimum capacity, Bowden suggests eating a daily serving of a probiotic-rich food like yogurt, kimchi, miso, sauerkraut, or buttermilk.
