1. Sit-ups: It can promote the exercise of abdominal, waist and thigh muscles, especially beneficial to shaping abdominal muscles, and can also play a role in losing weight. If you want to exercise your abdominal muscles, this is definitely the best choice.

2. Push-ups: You can exercise the strength of upper limbs, waist and back, especially the balance and support of the body. Long-term exercise can correct standing posture and sitting posture, making people behave dignified and generous.

3. Flat support: Like push-ups, it can play the role of exercise balance, which can also play the role of losing weight and shaping. It can also relieve mental stress and exercise willpower. However, it should be noted that people with osteoporosis, lumbar disc herniation or other symptoms cannot do this exercise.

4. Aerobics: I think everyone is absolutely familiar with aerobics. There are many kinds of aerobic exercise. You can find the video you want to practice, and it takes up little space and can be done indoors.

Finally, it is worth noting that you must warm up before exercise to make your body move, instead of starting fitness without doing any pre-exercise. This can easily lead to cramps or other symptoms.
