Strong Keto BHB The single best way to Slim Belly is HIIT... better known as high intensity interval training. This is an intense type of training that is brief. Having worked with thousands of people, I can tell you that most would like to avoid this type of training. So besides that, the best way to drop inches from your stomach is doing the vacuum pose. This is nothing more than sucking in your belly and holding it for 3-10 seconds. You do this for a total of no less than 5 minutes everyday. A great way to do these is during tv commercials. Expect about a 2 inch loss from your belly in 3-4 weeks.
