Since we can’t spot reduce fat, the only way to ever get those flat abs is to burn body fat overall. For this reason, HIIT workouts, exercises that work multiple muscle groups simultaneously (like push ups, squat thrusters etc.), and weight lifting are going to be the most effective fitness strategies for bringing out your six pack because they are the most metabolic. Hours of cardio and tons of crunches are not the way forward here.
#1 – Eat enough food! Your body can’t function without it’s fuel! You need a MINIMUM of 1200 calories a day for woman, but I personally recommend at least 1500, but you should consult your doctor for a better amount. Just remember if you don’t eat enough, your body goes into starvation mode and will store everything as fat. Also if you eat to much, you’ll gain! Remember 1lbs is 3500 calories! Your body burns calories when we do nothing so dont’ think you’ll gain 3500 calories if you eat that in a week. Here’s more information about that. It’s to hard for me to explain. http://www.caloriesperhour.com/tutorial_BMR.php
I played tennis from my freshman through junior year of high school and, again, really enjoyed the sport, but abhorred the running. Our coach was a middle-aged guy who could run circles around me. The entire team would have finished their laps around the field, while I was still stumbling along next to the (also middle-aged) assistant coach, who I’m quite sure they sent in as an attempt to get me to run faster.
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
