To lose 20 pounds by swimming, you will have to swim regularly every day and increase your speed and distance each time you step into the pool.
Swimming works every muscle in your body, and it helps to keep you toned and fit. It is actually one of the best forms of exercise that you can get. However, be aware that if you get in the pool and paddle around for 30 minutes, you are not going to lose much, if any, weight. You have to swim far and fast to burn a significant number of calories and get to a point where you can lose 20 pounds or more.
It will be much better for you if you swim in a pool as opposed to free swimming in a lake or river. You can time your laps and keep track of the distance you have gone in a pool, and there are no obstacles to avoid. To lose the 20 pounds in any amount of time, you are going to have to be consistent in your swim workouts. Swimming every day is ideal. Thirty minutes in a pool would be the time you should allot yourself.
How long it will take to lose the weight depends on the kind of swimmer you are and how often you go swimming. A strenuous workout is capable of burning about 200 to 300 calories. So, how long it takes to lose 20 pounds will all depend on how often you swim and how hard you push yourself.
Some people find that they are extremely hungry after a good swim, so it is up to you to keep you appetite under control. If you have spent 30 minutes or more in the pool and you get out and eat a big meal then you are defeating the purpose. Therefore, it will take you a lot longer to lose 20 pounds. It is recommended that you eat 4 to 5 smaller meals so that your metabolism will increase and you are less likely to experience the extreme hunger.
Water walking helps you burn calories, as does any water aerobics. Anything that involves resistance will help the weight come off. Walking in the water burns more calories than walking on land because of the resistance of the water.
It is not only possible, but highly probable that the weight will come off if you stick to a regular pool exercise routine. You may lose 20 pounds in three months if you are persistent. By making swimming a part of your regular exercise routine, you not only lose the weight but you keep it off as well.
