I have heard that if the abdominal muscles are flexed deliberately (kind of forcibly) throughout the day, it increases metabolism and helps reduce weight. I have a few questions regarding this as I am trying to reduce weight:

  1. Is it true?
  2. If yes, how safe is it?
  3. How long should I do it (e.g. the whole day or a few minutes each day)?

suck in your gut – jlg Nov 17 '11 at 21:11

Pulling your stomach muscles in will help keep them active. It doesn't necessarily increase metabolism and help reduce weight, but it does help your muscles get a tiny workout. Keeping the muscles in your abs active will make it easier to use them when you do workouts like crunches, sit ups, and anything else involving your abs.

It doesn't matter how long you do it, it's perfectly safe because you are just working on your muscles. It doesn't hurt if you do it all day long or for 2 minutes 3 times a day.

I try to remember to use this technique when I am doing something rather sedentary, like doing dishes or driving in my car.

Doesn't do much. I have tried for the past 6 mos and i still have a little gut. Probably time to get serious and do more ab workouts.

Hi @smith288, care to explain why keeping your abs flexed doesn't work? Do you have any other alternative or suggestions that would help? – Matt Chan Jan 14 '12 at 21:29
Not saying it won't help nominally but nothing beats a good old fashioned abs exercise and core fitness to burn total body fat and build abdominal muscle. – smith288 Jan 19 '12 at 22:41
