Staying Active in Winter: How to Warm Up Joints Safely

As the temperature drops, it becomes significantly harder to lace up your shoes and head outside for a workout. You might also notice that your body feels a bit stiffer, your knees ache a little more, and it takes longer to “get going.” This isn’t just in your head; cold weather causes muscles to contract and lose heat, making them less elastic and more prone to strains.

When the fluid in your joints (synovial fluid) is cold, it’s thicker—acting more like molasses than lubricant. Skipping your warm-up in winter is a fast track to an injury.

To keep your joints happy and your workouts safe this season, adjust your routine with these three warm-up rules:

  • Ditch the Static Stretching: Never stretch a cold muscle. Holding a static stretch in the cold can cause micro-tears. Instead, save the long holds for after your workout.

  • Focus on Dynamic Movements: Spend 10 minutes doing dynamic movements that mimic your workout. Think bodyweight squats, leg swings, arm circles, and high knees. This actively pumps warm blood into the muscles and thins out that joint fluid.

  • Layer Up Intentionally: Keep your joints covered with warm layers during the warm-up phase. You want to trap body heat early, and you can always shed layers once your internal thermostat kicks in.

Don’t let the colder months stall your fitness progress. A smart, deliberate warm-up protects your joints, improves your performance, and keeps you moving comfortably all year round.
