In addition to this, you must also avoid sugary products (pastry, candy bars, coke etc), as sugar has a series of negative effects on your health, and it also contributes to belly fat which is the most difficult to get rid of!  Of course you will be tempted now and again so have a cheat day once a week when you can have your favourite “bad foods” but don’t go too crazy!
On hardwood or tiled floor, place feet on two sliders and assume a high plank position (hands under shoulders, soft bend in elbows, butt and core engaged). Pull feet in toward chest, bending knees until you’re in a bear plank, knees below hips, but still lifted off floor. Slowly push feet back to high plank. Continue to repeat. To make it easier, move one leg at a time.
Lie down on a mat and place your hands behind your head, gently supporting your head with your fingers without pulling. Bring your knee up to your chest, while rotating your upper body to meet your knee with the elbow of your opposite arm (see photo). The opposite leg will go straight out. Switch to the opposite side, “cycling” the legs. Do one to three sets of 12 to 16 repetitions each.

Health fats is another valuable source in order to get lean muscles such as fish oils, raw nuts, olive oils and nut butters into your eating routine. These sources will keep your insulin levels stable, which is very salient if you will likely lose stomach fat and uncover well defined abs. I am not saying to go out there and eat a whole sack of Planters Cashews.
To do it: Stand with your feet hip-width apart, shoulders down, and your abs drawn in. Hinge forward at your waist and inch forward, walking with your hands into a top-of-the-pushup (or plank) position. Hold plank for three seconds, being sure to keep your chest lifted and your belly button drawn into your spine. Your body should form a straight line from your ears to your ankles. Then, perform one pushup by bending your elbows to the sides and lowering your body towards (but not touching) the floor, maintaining a straight spine.
The long arm crunch is ranked the 6th most effective ab exercise, changing the traditional floor crunch by straightening the arms behind you. This adds a longer lever to the move, adding a bit more challenge and difficulty. This move also emphasizes the upper part of the abs, although it's important to remember that your rectus abdominis is actually one long muscle that travels from your lower chest to your pelvis. While you can emphasize one part, any exercise you do will work the entire muscle.

"But after having children and maturing, my body image has changed. I don’t run or eat to look a certain way, but instead to feel a certain way—happy. I no longer count calories or restrict what I eat. I focus on real food that’s minimally processed, and most meals include some sort of carbs (I really love potatoes), protein, and lots of veggies. All of that, coupled with higher mileage during more intense marathon training, has led me to how I look today. When I’m not in the middle of marathon training, I’m often five to 10 pounds heavier—and that’s totally okay.” —Michele Gonzalez, @nycrunningmama
But instead of just trying to perform as many reps as possible, slow down and really focus on the quality of the movement—especially the eccentric, or downward motion, of the exercise, he says. “The eccentric contraction is the most important phase when sculpting any muscle.” Plus, focusing on quality over quantity will help protect your back (some experts say crunches can be potentially troublesome for guys with back issues.)
