In fact, like many athletes now, they started to exercise at first because of physical problems. Doctors said they couldn't exercise, and some even said they couldn't run, but they became national athletes and became excellent. Take part in the Olympic Games. Win glory for our country. Both long-distance runners and swimmers, like the recently famous Ning Zetao, suffered from heart disease when they were young. Can't do strenuous exercise. But he chose to learn to swim, and he swam better and better, and he made achievements. Although we can't do it, we can't be as legendary as them. After all, there are very few such people. But we can also have our own dreams. In the face of dreams, all our problems are not problems.
There are many people with bad hearts. If you don't improve yourself through exercise, your health will only get worse and worse, and exercise will make you stronger. Just never go to the gym blindly, you must be targeted and have goals. You can't do strenuous exercise as soon as you get up, and you can't overload your heart. Little by little. Take your time. You can't challenge, you must do exercise and fitness within your ability. After all, it is still important. This fitness level must consult the corresponding doctors and coaches. You can't do it blindly by yourself. Health is the most important thing.
I hope you can adjust yourself as soon as possible and get well soon.
