My tummy is flabby. what should i do to tone it?

Planks: Try planks. You hold yourself as if you were going to do push ups but don't go down. Hold as long as you can, then you can work on side planks to define the obliques.

Excess skin??: Have you had kids? Do you exercise? It usually is excess skin from being stretched after having kids, but you aren't giving much information to go on. Sorry.

Choices: Depending on the details of your situation, you might benefit from: 1) liposuction (or coolsculpting) 2) tummy tuck 3) a combination of both. Best to see a board-certified plastic surgeon for a consultation and exam to see which would be the correct choice.

Ab Flab: For flat abdomen eat healthfully ; be physically active. Calories burned must > calories consumed. To tighten ab's: crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge ; “bicycling” exercise on your back. Engage in regular aerobic exercise (i.e., running, swimming, nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.). >.
