During winter fitness, pay attention to these key issues: Dress in layers to stay warm but avoid overheating. Warm up longer than usual, as cold weather can stiffen muscles and increase injury risk. Be cautious of icy or slippery surfaces—wear shoes with good traction. Hydration is still essential, even if you don’t feel as thirsty. Cold air can irritate your lungs, so cover your mouth and nose with a scarf or mask to warm the air before breathing. If it’s extremely cold or windy, consider indoor workouts to avoid frostbite or hypothermia. Always listen to your body and adjust intensity as needed.
