Dress in layers to keep yourself dry. Maintains your body temperature while exercising in the cold. Avoid wearing synthetic materials such as polyester when exercising in the cold. These fabrics don't breathe well and can trap heat against your body. Instead, choose breathable fabrics such as cotton or wool.

Wear clothes that fit comfortably; if you feel restricted in any way, you won't be able to work out effectively. You should also wear appropriate footwear for cold weather workouts. You can buy a pair of athletic shoes for $50-100 that are designed for outdoor use. If you don't have any yet, no need to worry about buying new ones: old sneakers can be reused by removing their soles and replacing them with clean, dried sandals for use as winter boots. Finally, carry with you something warm to wear during your workouts. A sweatshirt or jacket is enough to stay warm for short periods of time. If you plan on working out for more than an hour, consider bringing a blanket or heating pad so you can relax after your session is over.
