Start weight training
Start a weight training routine of four to six exercises for three to five days every week. A good weight-training regime includes squats, bicep curls, triceps curls and bench presses. Several variations of each exercise are available, however, consulting a physician to put together a comprehensive strength-training routine for weight gain based on what you is available to you would serve you best.
The Basic Crunch
Lie flat on the floor on your back with your knees bent and your feet flat on the floor. Put your hands behind your head to support it. Now, lift your shoulders a few inches off the floor with only your ab muscles. Keep your upper body up for 3 seconds and lie back on the floor. Do about 10-12 of these crunches.
Standing Towel Circle
Stand straight and hold your resistance band or if you don't have that, a small towel will work as well and stretch it over your head. Squeeze your stomach and slowly make a large and wide circle over your head and around your trunk with your hands. Make sure you keep the towel or band stretched all the time. When you have completed one circle of this move, go back to where you started and start doing it the other way. Make sure you do this for 8-10 times on each side.
Oblique Twist with Ball
Sit straight on your ball and start walking with your feet forward while you are sitting on the ball until the ball is holding your back up and you are in the same line as the floor. Put your hand behind your head to help you to make crunches. Use your stomach to lift your shoulder blades off your ball and rotate your left shoulder to the right side of your hip. Go back to the position where you started and do it on the other side. Do this for about 8-10 times on each side.
Drink more water
Drinking more water lowers the amount of fat stored in the body. If you don't drink ample water, your kidneys may pass most of its unfinished work to your liver. One of your liver's functions is to help your body burn stored fat for energy and it can't perform that job fully if it has to do what the kidney’s do also. So, it is always recommended that one drink lots of water.
Drink Green Tea
Studies show that one can burn 35-43 percent more fat during the day by drinking 3-5 cups of green tea. If you do not have time to make your own green tea, you can simply take a green tea diet pill supplement.
Chew your food longer
You should chew everything you eat at least 8-12 times. Eat slowly. Your body doesn't realize that you've had enough to eat until several minutes after you've had it.
Cut out liquid calories
Eliminate soda and sugary drinks such as sweetened ice tea, sports drinks and alcoholic beverages from your diet. Such drinks will add lots of unwanted calories. Instead, liven up the taste of water by adding lemon, lime, cucumber or mint. Also avoid full fat milk and go for low-fat dairy.
Don't sleep for too long or too short a duration because according to a study done by researchers at Laval University in Quebec, people who slept more than 8 hours and those who slept for less than 6 hours were more likely to gain weight than people who slept the normal 7-to-8 hours.
If you don't have time to go on an exercise program , buy a pedometer, and try to walk 10,000 steps a day to burn an extra 100 calories or more every day, adding up to you losing over 10 pounds a year with minimal effort on your part.
