No: 1, ignoring the assessment of your physical condition.
The more detailed you know about your physical condition, the more appropriate your fitness plan will be. Give a simple example: Do you know your body fat index and heart rate? If you don't know, ask the fitness instructor to do a test for you, and then adjust your fitness plan according to the test results.
No: 2, judging the fitness effect through numerical changes.
The decline in weight figures is really exciting, but it doesn't really explain the problem. Because losing weight can't reflect the relationship between muscle and fat in your body. Muscle takes up less volume than fat, so it is entirely possible that you look thinner, lose body fat, but gain weight. So, numbers can't tell everything.
No: 3. There is no clear fitness goal.
Setting an expected value plays an inestimable role in the implementation of the whole fitness plan. Because challenges and evaluability can help you stick to your plan, and the expected good results will always motivate you not to give up easily. Make a scientific training plan, such as losing 5 kilograms a month, or losing 2 centimeters around your waist, and keep it in mind at all times, you will be more motivated.
Fourth place. Attach importance to aerobic exercise and ignore strength training.
In the process of achieving weight loss goals, strength training is as important as aerobic exercise. Strength training helps to increase muscle groups, which consume much more calories than fat every day. Therefore, if the number of muscle groups in your body increases, even if you are just resting, the calories consumed will increase accordingly. However, if we can combine aerobic exercise with strength training, we will certainly get better results.
