What's a good way to achieve a flat tummy?

Other than: Diet and abdominal exercises, the other options are localized fat reduction with coolsculpting or liposuction, or a tummy tuck. Best to see a board-certified plastic surgeon to discuss in person.

Wants flat tummy: CoolSculpting is a machine that draws fat into a suction cup and then cools the tissue. The cooling freezes the fat. The fat cells die. Improvement in contour is usually seen 8-12 weeks later. Liposuction can also be used to reduce fat in an area with extraction of the fat via cannula. You might need an abdominoplasty if there is excess skin. See a board certified plastic surgeon for eval.

Tighten: For flatter abdomen eat healthy & get physically active. Calories burned > calories consumed. To tighten ab's: crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge & “bicycling” exercise on back. Engage in regular aerobic exercise (i.e. running, swimming, Nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.)
