5. Engage in resistance training aimed at your abs. In addition to eating right and losing weight, doing certain types of exercises can help you achieve a better-defined abdomen, Singer says. "I'm sure everybody knew somebody in high school who had tremendous abs who ate whatever he or she wanted and had tremendous abs without working out," Singer says. "Most of us aren't that lucky." If developing a six-pack is your goal, doing exercises aimed at your abs can be part of a successful regimen. Such workouts would include weighted crunches and weighted sit-ups, he says. Cardio workouts are helpful for shedding pounds, but won't, on their own, lead to defined abs.
Warm up and cool down for 5 to 10 minutes. Go for a brisk walk or jog, do jumping jacks, run in place, or jump rope at the start of your workouts. Moderate aerobic exercise will increase blood flow to your muscles, which reduces your risk of injuring yourself. When you finish working out, cool down for 5 to 10 minutes to help your muscles recover.[11]
If you want to get fit faster and burn more calories in less time, don't spend all your time in the so-called fat-burning zone. Instead, add some High Intensity Training (HIT) to your workouts a couple times each week. According to the American College of Sports Medicine, you can burn more calories in less time with short, high intensity exercise. You can also boost your overall cardiovascular fitness with this type of training. Be sure to slowly ramp up your intensity, however, or you could wind up with an injury.​
Lay flat on your back again for this one but this time, place a dumbbell between your feet with your knees completely bent and thighs pointing straight up. Hold on to the dumbbell with your feet and bring your legs up toward your chest making sure your lower back gets off the ground. Focus on using your abs to pull your legs up and not getting momentum from your knees or feet. 
Why it made the list: Yes, a leg exercise made the top 10 list for abs. Anyone who has ever pushed their potential in the squat knows exactly why! Sure, squat variations work the legs and lower back, but they also crush the abs. Both front and back squats force your abs and spinal erectors to work overtime to maintain a neutral, upright position. If both were not firing at high rates, you'd fold under the weight or drop in a split second.
Do some cardio right after your weight-training workouts. After weight training your body should be depleted of its carbohydrate stores. So, in my opinion this is the perfect time to do some cardio and tap into fat stores. Basically, the weight training puts your body in an enhanced fat-burning state so you might as well take advantage of it by doing some cardio!
This exercise will stretch many of the muscles responsible for posture that are sometimes tight and it strengthens those same muscles if they are weak. You may discover that when you first perform it, one side of your body is significantly stronger or tighter. For instance, a long-time discus thrower who has turned to his left for years, to initiate his throw, may have significantly stronger obliques on his left side.
Eat carbs. "There's this notion that carbs are bad and that you need crazy amounts of protein to be lean and fit," says Alcantara, who disagrees, and eats just as much carbs as protein, although the ideal ratio varies based on your goals. "Whatever you eat to get the results you want has to be sustainable, otherwise you're going to end up right back where you started with the same habits that got you there."
