1. Wear appropriate sportswear: choose breathable and sweat-absorbing sportswear to keep your body dry and warm.

2. Wear a hat and gloves: In cold weather, the head and hands easily lose heat, so wearing a hat and gloves can effectively keep warm.

3. Wear thermal underwear: Choosing breathable and sweat-absorbing thermal underwear helps to keep your body warm.

4. Prepare for warm-up: Before starting fitness, proper warm-up exercise can help the body adapt to the low temperature environment and reduce the risk of injury.

5. Control the intensity of exercise: When the weather is cold, appropriately reduce the intensity of exercise to avoid excessive sweating and hypothermia.

6. Replenish water: During exercise, replenish water in time to prevent dehydration and hypothermia.

7. Pay attention to indoor temperature: When exercising in the gym or indoors, pay attention to whether the indoor temperature is appropriate, so as to avoid the influence of too high or too low temperature on the body.
