What exercises can i do to lose chest and stomach fat quickly, in 3 days?

Cardio Mix: You can not target the abdomen specifically for weight loss - if you have adipose tissue to lose (not everyone does), then consider an increase in cardio and a balanced diet. However, do not always do the same exercise or you will increase your risks for stress injuries. Mix things up with walking, running, biking, swimming, or circuit training. Ultimately you need to burn more than you consume.

There is no such : Hing as natural spot fat loss. You need to lose weight in general & a certain % will be abdominal & chest fat. Eat healthfully & be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge & “bicycling” exercise on your back. Engage in regular aerobic exercise.
