If the physique is poor and obesity is obvious, first choose sports with little exercise, such as jogging, slow cycling, playing table tennis, swimming and skipping rope, playing Tai Ji Chuan, doing weight-loss exercises, etc.
After practicing for a period of time and strengthening your physique, choose a project with a large amount of exercise. If you are obese with poor physique, you should choose the lightest exercise at first, such as walking and practicing Qigong. When you are better, choose other sports. Don't rush to achieve success.
