1, riding a bike is empty
Lie flat on the ground, put your arms flat on your sides, lift your calf so that the thigh and calf are at 90 degrees, and then make the action of pedaling your bike. Pay attention to your breathing in the process of doing it, and be sure to be even, so as not to be too tired. When making 1, you can make 50 first and gradually increase the number. Don't underestimate this action. This action is especially effective for thin thighs, buttocks and obese abdomen. As long as this action is particularly standard, you can feel obvious results if you persist in doing it for half a month. The first time you do this action, you will feel particularly sore in your thighs, which shows that you have exercised your legs and proved that this action is very effective. You can do it at home at any time without spending a penny.
2. Flat plate support
If you want to exercise, you'd better choose flat support. Flat support evolved from push-ups, so the effect is also very good. Do it for two minutes at the first time, and then slowly increase it to 10 minute. The specific action is to face down, support your body with your hands and feet, bend your arms 90 degrees, and support your upper body to land on your toes, so that the whole body is in a straight line as if it were parallel to your body. This action can be exercised all over the body and can be performed anywhere.
Fitness can improve people's immunity and physical fitness, but it needs long-term persistence, so the above two actions not only save time, but also have a particularly good effect. When you start doing it, you can practice it every day. When the effect is obvious, you can do it three times a week.
