How to get a flat stomach in 48 hours

Do aerobic exercises daily. Sure, you can do 100 crunches a day, but if you've got a layer of belly fat covering up your ab work then what's the point? You need to burn the top layer of stomach fat to see the changes. Cardio exercises will heat up your core temperature and improve circulation, both of which will aid in acquiring a flat stomach. Strive for at least 30 minutes a day minimum, but include one to two days of rest each week.

Activities such as dancing, running, tae-bo, swimming, cycling and walking at a good pace will all provide a great aerobic workout, in fact, anything that brings your heart rate up will do the trick! Boxing provides an excellent cardio workout, while the muscles involved in throwing punches will help to flatten your stomach.

 Try interval cardio training, such as alternating between sprinting and power walking. You can try sprinting for as long as you can. When you become too tired, you should walk. When you feel that you've caught your breath, sprint again. Do these alterations for a total of 20 minutes at a time. 

 Include plyometrics. Plyometrics are exercises that require "explosive power." They combine cardio with strength training. Some great plyometric exercises you can do at home include:

 Modified jumping jacks. Start standing, then jump up with hands and feet spread apart, creating an "X" in the air with your body, then land back in standing. Repeat as many times as you can.

 Squat-thrust push-ups. Start in push-up position, do one push-up, then push off with your feet and pull your knees up to your chest so your feet land between your hands(still on the ground in push-up position), then jump as high as you can, arms over head. Squat back down with your hands on the floor, then jump back to push-up position again. Do as many as you can do well with good form. 

Incorporate strength training to build muscle. Having more muscle will increase your metabolism, so you'll burn calories faster over time.

 Crunches work the upper abdomen, leg raises work the lower abdomen, and side bends work the obliques (also known as love handles). About 15 to 25 reps each day should be enough. If you can do more than that, try adding a weights to your routine. Note that doing crunches will only build muscle underneath your existing belly fat, but will not burn that fat directly.

 Try using an exercise ball to work your tummy muscles. One great exercise is called the ball exchange. 

Lie flat on your back, with your arms extended over your head, holding the exercise ball. Lift the ball above your chest, simultaneously raising your legs (keeping them completely straight) off the ground. Place the ball between your ankles, then lower your arms and legs to the floor. Repeat the exchange, this time passing the ball from your ankles to your hands. Do 10 to 12 repetitions.
