Patients with arthritis and osteoporosis: These patients need to avoid high-intensity and high-impact sports, such as running and jumping, so as not to aggravate the symptoms of arthritis or osteoporosis.
Patients with muscle strain or ligament injury: such patients need to avoid strenuous exercise and excessive stretching, so as not to aggravate the symptoms of muscle strain or ligament injury.
Hunger: Training in a hungry state should be avoided before fitness, because hunger will lower blood sugar and affect the effect and safety of exercise.
Lack of sleep: Lack of sleep will lead to physical fatigue, affecting sports ability and recovery ability. Therefore, it is recommended to ensure adequate sleep time.
