It seems obvious. If you want a toned tummy, you need to do a ton of sit ups, right? That’s what you see on the late night infomercials with all of the different ab machines and videos. Gym goers seem to be apt to use all sorts of ab machines as well, just adding to the seeming evidence that all those exercises and machines are the way to a flat tummy. But don’t assume so fast.
It’s not necessarily what you think.
Science is not as simple as you may imagine. Unfortunately, as science has shown, you can’t pick and choose your body parts so easily. Targeted fat loss and spot reduction is a myth.
A 2007 study from the University of Connecticut had participants use a single-arm strength training program. They didn’t lose fat from one arm. They lost fat in general. In short, you can work one area, but your body will decide how to lose the fat. Likewise, a study at Los Lagos University in Osorno, Chile found that those who completed single leg exercises reduced fat, but it wasn’t necessarily in that one leg.
As JC Deen, creator of JCD fitness puts it, Yes, exercise can burn fat. Trouble is, the body is not selective about where this fat, or fuel, comes from. The pattern in which fat leave your wondrous bodily temple is all up to Mother Nature.
Our genetics are making the actual fat loss decisions for us.
This doesn’t mean that ab exercises are necessarily bad. You will be working that muscle. However, if you put your focus on full body exercises that also work your core, you are more likely to exert more energy to burn more calories, and therefore you get greater results than you would with a few crunches.
