Outdoor exercising requires you to pay attention to the weather. You cannot think of workout clothes as fashion clothing only. Of course, you must try to wear whatever is in vogue, but at the same time, remember the climatic conditions, too. If the weather is particularly windy, you must wear sufficient layers to protect yourself from the cold. If it is snowing in your place, you can wear a water-resistant outer layer. Remember to shield yourself so the cold does not reach you.
Rest after the session
Especially when it is cold outside. You cannot immediately transition from training and panting, to shuddering in the cold weather. So before you head out of the gym after the session, take some time and rest. Maybe, even cool out and stretch for a bit to rule out injuries.
Keep yourself hydrated
Winters may trick you into believing you are not thirsty, and, therefore, do not need to drink water as much. But, you are more likely to get dehydrated this way. And dehydration may affect your workout session and increase the risk of injury, as well. Have some water kept in room temperature both before and after your session.Wear shoes with a good grip
In places where it snows, the ground may be slippery. So if you are looking to go running, wear shoes that provide proper traction.
Protect your skin from the sun
Just because it is cold, does not mean you are immune to a sunburn. Before you step out, apply some sunscreen, and continue wearing sun protection regardless of the weather.
