Exercising in cold weather requires adjustments to ensure safety and effectiveness. Layering clothing is essential to regulate body temperature, starting with moisture-wicking materials, insulating layers, and a windproof outer layer. Warm-up exercises are more important than ever to prevent injuries as cold muscles are prone to strains. Hydration remains vital, as the body loses moisture through respiration and sweat. Choosing footwear with good traction prevents slips on icy surfaces.
