How to ease sore muscles after a hard workout
Ice your sore muscles.
When put ice on your muscles, your blood vessels contract, which reduces the swelling in your muscles and can relieve pain. You can either take a cold shower or use an ice pack to the same effect.
To use an ice pack : Wrap the ice pack or bag of ice in a cloth. You don't want to have the ice directly against your skin because if you leave it on for too long you can actually give yourself frostbite.
