Work your core. When many people think of core strengthening, they think of stomach crunches. Crunches are helpful for building abdominal muscles, but contrary to popular belief, crunches won't do much to lose the layer of fat stored in your belly, and can actually cause significant damage to the spine. Instead, try a workout routine that strengthens your whole core, like yoga, or try abdominal presses and planking.
Aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.
I am on day four and I am very discouraged. I don't feel as if I am losing any weight at all. I encourage you to complete the seven days. Don't be too disappointed if you don't lose all ten pounds. Everybody and metabolism is different. Do be careful, however, to follow the diet exactly. Don't eat less food than is recommended in your effort to lose weight as that will throw off the diet's chemistry.
