Doctor advises you to first check, is it really just for money?
Don't let improper exercise ruin your body

Without pursuing fitness as the purpose, if you don’t master scientific methods of exercise and don’t have professional guidance, you should choose low-intensity, safe exercises such as jogging, stationary cycling, etc.
‘Imitation’ type fitness
Exercise must not be imitated or referenced randomly. If you blindly follow the example, you may get injured at any time. If there is a professional teacher to guide you, he will choose appropriate exercises based on your physical condition, and correct your mistakes at any time to avoid injury.
Three days of fishing and two days of drying
Exercise and fitness is a system project, not just playing around can achieve the expected goals. Weight loss, at least one week you need to exercise more than 3 times, and each time is best 1 hour. This is because exercise first consumes glycogen, and it will not consume fat after about half an hour. Secondly, weight loss cannot rely solely on exercise, it also needs to be combined with appropriate diet. If the energy intake every day is always more than the consumption of energy or equal to the consumption of energy, it will be difficult to achieve the purpose of weight loss. In addition, exercise weight loss must at least take two or three months to see effects, when the weight reaches a certain extent, it will stabilize, if you want to continue to reduce or long-term maintain, you must continue to exercise, once stopped, dietary habits have not changed, the weight may quickly rebound.
Good at boasting and comparing with others
The main purpose of exercise should be to maintain physical health. If you only pursue faster, higher and stronger, exceeding your own capabilities, it is easy to cause sports injury or accidents. You must control your strength during exercise, and don't be competitive and aggressive, leading to fitness failure and injury.
Young people are not afraid to train hard
When there is no coach guidance and no experience, the only correct approach to exercise is from low to high, gradually increasing. Let exercise meet your body’s tolerance. The amount and intensity of exercise must be slowly increased, the amplitude should not be too large, and you shouldn’t increase too quickly. If you feel insomnia, fatigue, and affect your work and life after exercise, it means that the exercise volume or intensity is too high, next time you should reduce the amount or intensity. Even if you often exercise and have good physical fitness, if you don’t exercise for a period of time, you should also gradually recover from low to high.
Exercise anytime and anywhere
It’s not appropriate to exercise too early or too late. Before sunrise, the carbon dioxide content in the air is relatively high, and pollutants accumulate a lot, breathing these polluted air will have a harmful effect on the human body. Late-night exercise makes people too excited and affects sleep.
You can distinguish exercise time by age group: young people have strong adaptability and should exercise in the morning or afternoon; middle-aged people are better to relax after getting off work 6-8 points; the elderly are the weakest, they should exercise when the temperature is higher (that is, 2-5 points in the afternoon).
Don’t skip warm-up before exercise
Warm-up is to activate the body, play a warming, heating role, let the heart rate reach the state of exercise, which is necessary. Warm-up should be from head to toe, from top to bottom, all joints and tendons should be rotated. After exercise, you should also do appropriate relaxation to make breathing calm, accelerate lactic acid elimination, slow down muscle soreness, and promote the recovery of the body.
Actually, many netizens often ask me how to gain muscle or lose fat, I actually find it difficult to answer you this question, a coach just gives you a suggestion, if you don’t observe you, evaluate you, and don’t know your lifestyle, work, and diet habits, then it’s just a suggestion, not a personalized fitness plan suitable for you. You should first understand your weaknesses and strengths, so you can find your training method. Along the way, you make mistakes because of imitation, and now social media is everywhere with teaching, those are just his personal training methods and suitable for him actions, not necessarily suitable for you. So you also need to listen to the doctor’s advice, first check yourself, meaning you really need a coach.
