1. Know your body
Don't blindly challenge big weights and high strengths. These are not scientific. Only by finding the training methods and techniques that are right for your body can the fitness effect be better.
2. Test your physical fitness
Before starting a fitness exercise, be sure to test your physical fitness. In other words, how much you can bear. Such as cardiopulmonary, flexibility, muscle endurance and other aspects of the test (specific details can be learned from the gym's coach). In doing so, it is better to avoid the damage caused by fitness.
3. Check the body's body fat rate, etc.
Whether you are losing weight or gaining muscle, be sure to know what your body's body fat rate is. This will enable you to achieve your fitness goals faster and more systematically.
