1. Overtraining: Beginners often pursue the intensity and frequency of training too much when they start fitness, which leads to excessive fatigue. Beginners are advised to start training 2-3 times a week, and each training time should not exceed 1 hour, and gradually increase the training intensity and frequency.

2. Wrong strength training: Novices often ignore the correct movement skills in strength training, resulting in poor training results and even injuries. It is suggested that strength training should be carried out under the guidance of a professional coach to ensure correct movements.

3. Ignore warm-up and stretching: Warm-up and stretching are necessary links before fitness and help prevent sports injuries. Novices often ignore these two links, which may easily lead to problems such as muscle strain. It is recommended to warm up for 5- 10 minutes before each training, and then do full-body stretching after the training.

4. Unreasonable diet: Fitness is not only exercise, but also diet control. Beginners often fall into the misunderstanding of dieting or overeating, which affects their health and training effect. It is suggested to maintain a balanced diet and get enough protein, carbohydrates and fat to meet the body's needs.

5. Neglect recovery: Novices tend to neglect physical recovery during exercise. Proper rest and sleep are essential to the recovery of the body. It is recommended to ensure 7-8 hours of sleep every day and give your body adequate rest during the interval of training.

6. blindly follow the trend: novices are easily influenced by social media and networks and blindly imitate other people's fitness plans and eating habits. This practice may lead to poor training effect and even harm to the body. I suggest you make a proper fitness plan and diet arrangement according to your physical condition and goals.

7. Ignore individual differences: Everyone's physical condition and genes are different, and the fitness plan needs to vary from person to person. Beginners should fully consider their physical condition and goals when making fitness plans, and should not blindly follow suit. If necessary, you can consult a professional coach and make a personalized fitness plan.
