When I first started exercising, I couldn't do a push-up because of 1. I am actually a good exercise to measure my physical condition. Because it affects the back, shoulders, arms and core muscles. So if you are in good health, both men and women should be able to do at least a few. 2. It takes more time to slow down the heartbeat. When you exercise, your heart beats faster, so all the oxygen will be pumped to all parts of your body. When you are in good health, I can hurry up or slow down. If I don't exercise for too long and my heart and lung function are poor, it may take more time for my heart to return to normal. 3. The waistline is getting thicker and thicker. Even girls and men should get into the habit of measuring waist circumference to determine whether they have accumulated too much fat in the middle of their bodies. There is too much fat in the stomach, and life is also a typical manifestation of too much visceral fat, and too much visceral fat means that you are likely to have problems with your heart, kidneys, liver and digestive organs. 4. Climb the stairs, panting. Every normal person can't breathe when climbing stairs. It's wrong not to wear them, but they don't wear them well. Climbing stairs requires hard work, and their lower limb strength and endurance are too poor, and their cardiopulmonary ability is too poor. They need exercise. Wait, when you find that you can't control your body management and your physical fitness drops, you need to exercise.
