In the dormitory, we can exercise mainly "abdominal muscles" and "chest muscles". In addition, the muscles of our arms can also grow. I can tell you some simple steps based on my personal experience and understanding, hoping to encourage you.
1, make up your mind that exercise can't be effective in a day or two. You should have the confidence and determination to persist for a long time. I think this is also a necessary prerequisite for doing other things.
With determination, we have the motivation to move forward. About abdominal muscles, the simple way is to do sit-ups. You can do this in your own bed, which is very convenient. It's best to wear less clothes when doing it, which helps to put down and stretch. At first, you have to untie your ligament. You should know what to do, leg press. Split. Step by step according to individual affordability. Sit-ups will be performed after the body is pulled away. At first, you can do what you can according to your ability, and divide into 3-5 groups at a time. You can appropriately increase the number of people and groups in the future. This practice 10-20 days will be effective.
3. Push-ups. The method is the same as the sit-ups above. It's about persistence
Everything needs hard work, especially exercise, and you need the necessary sweat to get some results. When you have developed your first abdominal muscle, you will love sports and exercise.
